What is the typical 500 TPH crushing process? 24/9/2026
A typical 500 TPH crushing process is designed to produce approximately 500 tonnes of processed material per hour under the specified operating conditions. The exact process depends on the raw material, maximum feed size, required final products, and whether the plant needs two-stage or three-stage crushing.
For a hard-rock aggregate application, a common 500 TPH crushing process is:
Raw Material → Vibrating Feeder → Jaw Crusher → Cone Crusher → Vibrating Screen → Finished Products
In a closed-circuit configuration, oversize material from the vibrating screen is returned to the cone crusher for further crushing.
1. Feeding
Large rocks are loaded into a feed hopper and delivered to the primary crusher by a vibrating feeder.
The feeder provides a controlled and relatively stable flow of material, helping prevent overloading of the primary crusher.
2. Primary Crushing
A jaw crusher is commonly used for primary crushing when the feed material is large and hard.
Its main purpose is to reduce large rocks into a smaller size suitable for secondary crushing.
For example:
Maximum feed size → Primary jaw crusher → Intermediate crushed material
The actual crusher model and discharge size depend on the feed characteristics and required plant capacity.
3. Secondary Crushing
After primary crushing, the material is transported to the secondary crusher.
For hard and abrasive rock such as granite, basalt, or some types of ore, a cone crusher is commonly considered for secondary crushing.
The cone crusher further reduces the material and prepares it for screening.
4. Screening
The crushed material then enters a vibrating screen.
The screen separates the material into different size fractions according to the required product specifications.
For example, a 500 TPH aggregate plant may produce several products such as:
0–5 mm
5–10 mm
10–20 mm
20–31.5 mm
The actual product sizes depend on the customer's requirements.
5. Closed-Circuit Return
Material that is larger than the required screen opening is returned to the crusher through a return conveyor.
The basic closed-circuit flow is:
Jaw Crusher → Cone Crusher → Vibrating Screen
** ↘ Oversize → Return to Cone Crusher**
This allows correctly sized material to leave the circuit while oversize material continues to be processed.
No.
A 500 TPH plant can use either a two-stage or three-stage crushing circuit depending on the material and final product requirements.
A relatively simple configuration may be:
Jaw Crusher → Cone Crusher → Screen
A more complex configuration may be:
Jaw Crusher → Cone Crusher → Tertiary Crusher/VSI → Screen
A three-stage configuration may be considered when the plant requires finer products, higher reduction ratios, improved particle shape, or manufactured sand.
A typical hard-rock 500 TPH plant may include:
| Equipment | Main Function |
|---|---|
| Vibrating Feeder | Controls material feeding |
| Jaw Crusher | Primary crushing |
| Cone Crusher | Secondary crushing |
| Tertiary Crusher or VSI | Additional reduction or shaping |
| Vibrating Screen | Product classification |
| Belt Conveyors | Material transportation |
| Dust Control System | Dust suppression or collection |
| Electrical Control System | Plant operation and monitoring |
The exact equipment configuration should be determined after evaluating the raw material and final product requirements.
A plant rated around 500 TPH does not necessarily produce exactly 500 tonnes every hour under all conditions.
Actual production can be affected by:
Rock hardness
Abrasiveness
Maximum feed size
Feed gradation
Moisture content
Crusher settings
Screen efficiency
Circulating load
Equipment availability
Operator control
This is why crushing plant design should focus on the performance of the complete process, rather than selecting individual machines based only on their nominal capacity.
For a hard-rock aggregate project, a typical process could be:
Raw Granite
↓
Vibrating Feeder
↓
Jaw Crusher
↓
Cone Crusher
↓
Vibrating Screen
↓
0–5 mm + 5–10 mm + 10–20 mm + 20–31.5 mm
with oversize material returning to the cone crusher.
If manufactured sand or improved particle shape is required, a VSI crusher can be added:
Jaw Crusher → Cone Crusher → VSI → Vibrating Screen
The final configuration should be determined according to the customer's feed material, production target, final product specifications, and site conditions.
Stationary vs Mobile Crushing Plant: How to Choose 24/9/2026
When planning a new crushing project, one of the first decisions is whether to install a stationary crushing plant or use a mobile crushing plant.
Both solutions can handle demanding crushing applications, but they are designed for different operating conditions. Choosing the right configuration depends on factors such as project duration, material characteristics, production capacity, site conditions, transportation requirements, and long-term operating costs.
This guide explains the key differences between stationary and mobile crushing plants and provides a practical framework for choosing the right solution for your project.
A stationary crushing plant is a fixed crushing and screening system installed at a permanent location.
A typical stationary plant may include:
Vibrating feeder
Jaw crusher
Cone crusher or impact crusher
Vibrating screen
Belt conveyors
Transfer points
Dust suppression or environmental protection equipment
The equipment is normally arranged according to a carefully designed process flow. Once installed, the plant is intended to operate at the same location for many years.
Stationary plants are commonly used in:
Large quarries
Long-term aggregate production
Large-scale metal mines
Limestone and granite processing
Long-term construction material projects
High-capacity crushing operations
The main advantage is that the entire system can be optimized around a specific material, capacity, and final product requirement.
A mobile crushing plant integrates crushing equipment, feeding, screening, and sometimes conveying equipment on a movable chassis.
Depending on the configuration, a mobile plant may use:
Mobile jaw crusher
Mobile cone crusher
Mobile impact crusher
Mobile screening plant
Tracked crushing equipment
Tyre-mounted crushing equipment
The plant can be moved between working areas with less dismantling and installation work than a traditional stationary system.
Mobile crushing plants are particularly useful when:
The project site changes frequently
The raw material is distributed over a large area
Transportation distances need to be reduced
The project is temporary or relatively short-term
Infrastructure at the site is limited
Crushing needs to take place close to the excavation area
The following table summarizes the major differences:
| Factor | Stationary Crushing Plant | Mobile Crushing Plant |
|---|---|---|
| Installation | Requires fixed installation | Faster setup and relocation |
| Mobility | Limited | High |
| Long-term operation | Well suited | Also possible, depending on project |
| Site changes | Less flexible | Highly flexible |
| Infrastructure | Usually requires more infrastructure | Generally requires less fixed infrastructure |
| Layout optimization | Very high | More compact and flexible |
| Transportation | Material usually transported to plant | Crusher can move closer to material |
| Initial civil work | Usually higher | Usually lower |
| Large-scale production | Excellent | Excellent for suitable applications |
| Temporary projects | Less suitable | Highly suitable |
| Multiple working areas | Difficult | Easier |
| Long-term expansion | Easier to expand systematically | Depends on plant configuration |
Project duration is one of the most important factors.
If a quarry or mine is expected to operate at the same location for many years, a stationary plant may provide a more suitable long-term solution because the crushing circuit can be designed specifically around the expected production requirements.
For example, a large aggregate quarry producing several million tons per year may justify a permanent crushing and screening system with optimized conveyors, stockpiles, electrical systems, and automated controls.
On the other hand, a road construction project may only require crushing operations for a limited period. After the project moves to another section, the crushing equipment may also need to move.
In this situation, mobile crushing equipment can reduce the amount of dismantling and reconstruction required.
Transportation distance can have a significant effect on total operating costs.
If raw material must be hauled several kilometers from the excavation area to a stationary crushing plant, the project may require a large fleet of dump trucks or haulage equipment.
This can increase:
Fuel consumption
Labor costs
Truck maintenance
Road maintenance
Material handling time
A mobile crusher can sometimes be positioned closer to the excavation area.
The material is crushed near the source, which can reduce the amount of oversized material that needs to be transported.
However, mobile crushing is not automatically cheaper. The total economics should include the cost of moving the mobile equipment, maintaining the equipment, feeding the crusher, conveying the material, and managing the finished products.
The required production capacity should be considered before selecting the plant type.
For example, a project requiring approximately 100–200 TPH may have very different equipment requirements from a project requiring 500–1,000 TPH.
At higher capacities, the complete system becomes increasingly important.
A 500 TPH plant, for example, may require coordinated capacity across:
Feeding → Primary Crushing → Secondary Crushing → Screening → Final Products → Conveying
The actual capacity of the plant is determined by the performance of the complete circuit rather than the maximum theoretical capacity of one crusher.
For high-capacity long-term projects, a stationary plant can provide greater flexibility for optimizing the complete material flow.
For projects where production areas change, a mobile configuration may provide greater operational flexibility.
The type of material being processed also affects the decision.
Hard and abrasive materials such as granite, basalt, iron ore, and some other hard rocks require carefully selected crushing equipment and wear-resistant components.
For softer materials such as limestone, the crushing circuit may be configured differently.
Before choosing between stationary and mobile equipment, consider:
Material hardness
Abrasion
Maximum feed size
Moisture content
Clay content
Required reduction ratio
Final product sizes
Required production capacity
For example, a hard-rock project requiring multiple crushing stages may benefit from a carefully engineered combination of jaw crushers, cone crushers, and vibrating screens.
The number and size of final products can significantly affect plant design.
A simple application may require only one final aggregate size.
Another project may require several products such as:
0–5 mm manufactured sand
5–10 mm aggregate
10–20 mm aggregate
20–31.5 mm aggregate
When multiple products are required, the screening and recirculation system becomes more complicated.
A stationary plant provides more flexibility for designing permanent stockpiles, conveyors, screening stages, and closed-circuit crushing systems.
Mobile plants can also produce multiple sizes, but the configuration needs to be carefully planned around the available space and required mobility.
Site infrastructure is another major consideration.
A stationary plant may require:
Foundations
Electrical systems
Control rooms
Feed hoppers
Conveyor structures
Stockpile areas
Access roads
Dust suppression systems
Drainage systems
These investments can make sense for a long-term operation.
A mobile plant generally reduces the amount of permanent infrastructure required, although it still needs suitable access, power or fuel arrangements, material handling, and working space.
This makes mobile equipment attractive for projects where constructing permanent infrastructure would be difficult or uneconomical.
Both stationary and mobile crushing plants require regular maintenance.
Important maintenance areas include:
Crusher wear parts
Bearings
Lubrication systems
Hydraulic systems
Vibrating screens
Feeders
Conveyor belts
Motors
Electrical systems
Mobile equipment has the additional consideration that the entire crushing unit must withstand movement and relocation.
For either plant type, the availability of spare parts and technical service should be considered during the equipment selection stage.
A plant that has high theoretical capacity but frequent downtime may deliver less actual production than expected.
There is no universal answer.
The operating cost depends on the complete project configuration.
For a stationary plant, major costs may include:
Electricity
Material transportation
Conveyor operation
Wear parts
Labor
Maintenance
Infrastructure
For a mobile plant, major costs may include:
Fuel or electricity
Equipment relocation
Wear parts
Maintenance
Feeding and conveying
Operator costs
The correct comparison should therefore consider cost per ton, rather than simply comparing the purchase price of individual machines.
A useful calculation is:
Total Operating Cost ÷ Actual Production = Operating Cost per Ton
This provides a more meaningful basis for comparing different crushing solutions.
A stationary crushing plant is generally worth considering when:
The project will operate at the same location for many years
Production volume is large
The required capacity is high
The material source is relatively stable
Multiple final products are required
There is sufficient space for permanent infrastructure
The project requires a highly optimized crushing circuit
Future capacity expansion is expected
For a long-term quarry or mine, the ability to optimize the complete crushing and screening system can be an important advantage.
A mobile crushing plant may be more appropriate when:
The working location changes frequently
The project is temporary
Material sources are widely distributed
Reducing haulage distance is important
Permanent infrastructure is difficult to build
The project requires rapid deployment
The crushing plant needs to follow the mining face
For construction and infrastructure projects, mobility can be particularly valuable because the location of the material source may change as the project progresses.
Yes.
In some large projects, a combination of mobile and stationary equipment can provide an efficient solution.
For example, mobile crushers can perform primary crushing near the excavation area, while a stationary secondary and screening system handles further processing.
A simplified process could be:
Excavation → Mobile Primary Crusher → Conveying → Secondary Crusher → Screening → Finished Products
This type of hybrid configuration can reduce haulage requirements while maintaining the processing efficiency of a more permanent crushing circuit.
The best arrangement depends on the distance between the mining face and processing plant, production capacity, material characteristics, and project layout.
Before selecting stationary or mobile crushing equipment, answer these questions:
How long will the project operate?
Will the material source remain in the same location?
What is the required capacity in TPH?
What is the maximum feed size?
What type of material will be processed?
How hard and abrasive is the material?
What final product sizes are required?
How many final products are needed?
How far must the raw material be transported?
Is permanent infrastructure available?
Will the crushing plant need to move during the project?
What is the expected operating cost per ton?
Is future capacity expansion required?
These questions provide a practical starting point for plant selection.
The choice between a stationary and mobile crushing plant should not be based on equipment price alone.
A better approach is to evaluate the entire production system, including material characteristics, capacity, transportation distance, project duration, final product requirements, infrastructure, maintenance, and cost per ton.
A stationary plant is typically designed around long-term, stable production at a fixed location, while a mobile plant provides greater flexibility when the working area changes.
For some projects, a hybrid solution may also be appropriate.
The right crushing plant is ultimately the one that matches the actual conditions of the mine, quarry, or construction project and delivers the required production with stable operation and manageable total costs.
Not necessarily. The total cost depends on equipment investment, transportation, infrastructure, fuel or electricity, maintenance, wear parts, labor, and actual production.
Yes. Mobile plants can be equipped with jaw crushers, cone crushers, or other crushing equipment suitable for hard and abrasive materials. The crusher and wear parts should be selected according to the material characteristics.
Yes. With suitable screening equipment, a mobile crushing system can produce multiple aggregate sizes. The required number of products should be considered during the initial plant design.
A stationary crushing plant is often considered for long-term quarry operations because the complete crushing, screening, conveying, and stockpiling system can be optimized around a permanent site.
Yes. A hybrid system can combine mobile primary crushing with stationary secondary crushing and screening, depending on the project requirements.
Compare the complete system rather than individual machine prices. Key factors include actual production capacity, energy consumption, transportation costs, wear parts, maintenance, labor, infrastructure, and cost per ton.
2-Stage vs. 3-Stage Crushing: Which Crushing Circuit Is Right for Your Plant? 17/9/2026
Choosing the right crushing circuit is one of the most important decisions when designing a mining or aggregate processing plant.
A two-stage crushing plant may be sufficient for some applications, while a three-stage circuit may be necessary when the feed material is large, the final product is fine, or strict particle-size and shape requirements must be met.
The choice should not be based simply on the number of crushers. Raw material characteristics, feed size, required capacity, final product specifications, particle shape, energy consumption, and operating costs all need to be considered.
This guide explains the differences between 2-stage and 3-stage crushing circuits and provides practical guidance for selecting the right configuration for your plant.
A crushing circuit is the sequence in which material passes through different crushing and screening stages to achieve the required product size.
A typical crushing process may include:
Feeding → Primary Crushing → Secondary Crushing → Screening → Finished Products
When additional size reduction or shaping is required, a tertiary stage can be added:
Feeding → Primary Crushing → Secondary Crushing → Tertiary Crushing → Screening → Finished Products
The final circuit depends on the relationship between the raw material and the required finished product.
A 2-stage crushing circuit uses two main crushing stages.
A common configuration is:
Primary Crusher → Secondary Crusher → Screening
For hard rock aggregate production, a typical equipment combination may be:
Jaw Crusher → Cone Crusher → Vibrating Screen
The jaw crusher performs the primary size reduction, while the cone crusher further reduces the material before screening.
Oversize material can be returned to the secondary crusher in a closed circuit.
Raw Material
↓
Vibrating Feeder
↓
Jaw Crusher
↓
Cone Crusher
↓
Vibrating Screen
↓
Finished Aggregate
With closed-circuit operation:
Screen Oversize → Return to Cone Crusher
A two-stage circuit can provide a relatively simple process with fewer crushing machines and less equipment to maintain.
A 3-stage crushing circuit adds a tertiary crushing stage after primary and secondary crushing.
A typical configuration is:
Primary Crusher → Secondary Crusher → Tertiary Crusher → Screening
For aggregate applications, the equipment may include:
Jaw Crusher → Cone Crusher → Cone Crusher or VSI Crusher → Vibrating Screen
The tertiary stage provides additional size reduction and, depending on the equipment selected, can also improve particle shape or produce manufactured sand.
Raw Material

Vibrating Feeder

Secondary Cone Crusher

Multiple Finished Products
Oversize material can be returned to the appropriate crushing stage.
| Factor | 2-Stage Crushing | 3-Stage Crushing |
|---|---|---|
| Number of crushing stages | Two | Three |
| Process complexity | Relatively simple | More complex |
| Equipment investment | Generally lower | Generally higher |
| Maintenance points | Fewer | More |
| Fine product production | Application dependent | Better suited to finer products |
| Particle shape control | Depends on crusher and material | More process flexibility |
| High reduction requirements | May be limited | More suitable |
| Multiple final products | Possible | More flexibility |
| Manufactured sand | May require additional equipment | Often easier to integrate |
| Suitable applications | Moderate reduction | Higher reduction or stricter product requirements |
The table provides a general comparison. Actual performance depends on equipment selection, material properties, operating conditions, and plant design.
A two-stage circuit may be appropriate when the feed material does not require an extremely high reduction ratio and the final product specifications can be achieved through primary and secondary crushing.
Typical applications include:
Aggregate production
Limestone crushing
Some granite applications
Road base production
Quarry material processing
Projects with relatively straightforward product requirements
For example, a quarry may receive large rock and need to produce several coarse aggregate sizes without requiring a large amount of manufactured sand.
In such cases, adding a third crushing stage may increase equipment and operating costs without providing enough additional benefit.
A three-stage circuit may be considered when the required size reduction cannot be efficiently achieved through two stages alone.
It can be useful when:
Feed size is relatively large
Final product size is relatively fine
A narrow product-size distribution is required
Several final products are required
Better particle shape is important
Manufactured sand is part of the product mix
The material is hard and difficult to reduce efficiently in fewer stages
For example, a granite aggregate plant may use a jaw crusher for primary crushing, a cone crusher for secondary crushing, and a VSI crusher for tertiary crushing and shaping.
Feed size is one of the first factors to evaluate.
If the raw material contains very large rocks, the primary crusher must be capable of handling the maximum feed size.
However, the primary crusher does not need to produce the final product size. Its main purpose is to reduce the material sufficiently for the next crushing stage.
The secondary and tertiary stages then progressively reduce the material.
This staged reduction allows each crusher to operate within a suitable range instead of forcing one machine to perform excessive size reduction.
The required final product size is another major consideration.
If the customer requires relatively coarse aggregate, a two-stage circuit may be sufficient.
If the plant must produce fine aggregate or manufactured sand, additional crushing and shaping may be required.
For example:
Large Rock → Primary Crushing → Secondary Crushing → Coarse Aggregate
may require fewer stages than:
Large Rock → Primary Crushing → Secondary Crushing → Tertiary Crushing → Screening → Fine Aggregate and Manufactured Sand
The smaller the target product size, the more carefully the crushing ratio and screening process need to be designed.
Screening is essential in both types of crushing circuits.
A vibrating screen separates material according to particle size and determines which material continues to the next stage.
In a closed circuit, oversize material is returned to the crusher.
For example:
Crusher → Screen → Finished Product
** ↘ Oversize → Crusher**
This allows the plant to continuously remove correctly sized material while recirculating oversize material.
An inefficient screen can therefore reduce the performance of the entire crushing circuit.
Particle shape can be particularly important in aggregate production.
Some construction applications have requirements related to the shape and proportion of flaky or elongated particles.
Cone crushers can produce well-shaped aggregates under appropriate operating conditions, but additional shaping may be required for certain applications.
A VSI crusher can be integrated as a tertiary stage when the plant needs additional particle shaping or manufactured sand production.
This does not mean that every aggregate plant needs a VSI crusher. The decision depends on the final product specifications and the characteristics of the material.
A basic hard-rock aggregate plant could use:
Vibrating Feeder
↓
Jaw Crusher
↓
Cone Crusher
↓
Vibrating Screen
↓
Final Aggregates
The screen may divide the material into several product sizes.
Oversize material is returned to the cone crusher for additional processing.
This type of circuit can be suitable when the final products do not require extensive shaping or very fine fractions.
For a project requiring finer products and improved particle shape, the process could be:
Vibrating Feeder
↓
Jaw Crusher
↓
Cone Crusher
↓
VSI Crusher
↓
Vibrating Screen
↓
Finished Aggregates + Manufactured Sand
Oversize material from the screen can be returned to the appropriate crushing stage.
The additional stage provides more control over the final product but also increases equipment investment, maintenance requirements, and energy consumption.
The number of crushing stages affects operating costs, but it should not be evaluated independently.
A three-stage circuit has additional equipment, which means additional power consumption and maintenance requirements.
However, using an additional stage can sometimes improve overall process efficiency by distributing size reduction across several machines.
Forcing a secondary crusher to perform excessive reduction may result in:
Higher energy consumption
Increased wear
Lower efficiency
More fines
Higher circulating load
Therefore, the lowest equipment count is not always the lowest-cost solution.
The correct question is:
Which crushing circuit can produce the required products at the lowest reasonable cost per tonne?
Every additional crushing stage introduces additional wear components and maintenance points.
Typical wear parts include:
Jaw plates
Cone crusher liners
VSI wear parts
Screen media
Conveyor components
Hard and abrasive materials can accelerate wear.
For this reason, the expected wear-part consumption should be considered during circuit selection.
A slightly more complex crushing circuit may be economically reasonable if it reduces excessive wear on individual machines and provides more stable production.
A practical decision process can follow these steps.
Determine:
Rock type
Hardness
Abrasiveness
Maximum feed size
Moisture
Clay content
Particle characteristics
Determine the required production rate in tonnes per hour.
The feeder, crushers, screens, and conveyors should then be sized as an integrated system.
List every required product size.
For example:
0–5 mm
5–10 mm
10–20 mm
20–31.5 mm
The more product sizes and finer fractions required, the more important the screening and tertiary stages become.
If the products have strict shape requirements, consider whether an additional crushing or shaping stage is necessary.
Consider:
Initial investment
Power consumption
Wear parts
Maintenance
Labor
Expected production
Cost per tonne
The objective is to evaluate the complete life-cycle cost rather than only the initial equipment price.
More equipment does not automatically mean better production.
If the final products can already be achieved with two stages, an unnecessary third stage may increase costs.
The capacity of individual crushers does not represent the capacity of the entire plant.
The feeder, screen, conveyor, and return circuit can all become bottlenecks.
The crushing circuit should be designed backward from the required products.
Without clear product specifications, it is difficult to determine the appropriate number of crushing stages.
In a closed circuit, oversize material returns to the crusher.
If the screen is undersized or crusher settings are inappropriate, circulating load can become excessive and reduce overall plant efficiency.
It can be sufficient for many aggregate applications, particularly when the required product sizes and particle-shape specifications can be achieved through primary and secondary crushing. The actual configuration depends on the material and final product requirements.
Neither configuration is universally suitable for every project. A three-stage circuit provides an additional size-reduction or shaping stage, while a two-stage circuit can offer a simpler process when fewer stages are sufficient.
A common hard-rock configuration is a jaw crusher for primary crushing followed by a cone crusher for secondary crushing, with vibrating screens for classification.
A typical configuration may include a jaw crusher, secondary cone crusher, and tertiary cone or VSI crusher, depending on the material and final product requirements.
A three-stage circuit adds another crushing stage and therefore introduces additional power and maintenance requirements. However, distributing size reduction across multiple stages can also improve the overall process when a high reduction ratio or finer products are required.
A VSI crusher may be considered when the plant requires additional particle shaping or manufactured sand production. Its suitability depends on the material, feed size, required products, and existing crushing circuit.
There is no fixed number. The appropriate number of stages depends on feed size, material properties, required capacity, final product size, particle shape requirements, and downstream processing.
The choice between 2-stage and 3-stage crushing should be based on the complete production process rather than the number of crushers.
A two-stage circuit can provide a relatively simple and efficient solution when the material and product requirements can be achieved with primary and secondary crushing.
A three-stage circuit provides additional size reduction and process flexibility when finer products, higher reduction ratios, multiple product sizes, or improved particle shape are required.
The key is to match the crushing circuit with the actual project:
Raw Material → Feed Size → Required Capacity → Crushing Stages → Screening → Final Products
When these factors are properly matched, the crushing plant can achieve a better balance between production capacity, product quality, energy consumption, wear-part usage, and long-term operating costs.
