This case study presents a stationary crushing production line specifically designed for processing limestone. The production line is equipped with state-of-the-art machinery to ensure efficient and consistent crushing of limestone, meeting specific size requirements for various applications.

Material Processed:

• Limestone

Feed Size:

• The maximum input size of the limestone material is ≤720mm.

Output Sizes:

• The production line is capable of producing crushed limestone in multiple sizes: 8mm, 20mm, 32mm, 50mm, and 85mm.

Production Capacity:

• The designed hourly capacity of the production line is 300 tons per hour (T/H), ensuring high throughput and productivity.

Equipment Configuration:

1. Hopper (Material Storage Bin):

• The production line begins with a large hopper where the raw limestone material is stored before being fed into the crushing process. The hopper is designed to hold sufficient material to maintain continuous operation.

2. Feeder (Feeding Machine):

• A vibrating feeder is installed below the hopper to regulate the flow of limestone into the jaw crusher. This ensures a consistent and controlled feed rate, preventing overloading and maintaining optimal crushing efficiency.

3. Jaw Crusher:

• The core of the production line is a robust jaw crusher, capable of reducing the size of the limestone from ≤720mm to a more manageable size for further processing. The jaw crusher is known for its high crushing ratio and reliability.

4. Conveyor Belt (Belt Conveyor):

• After being crushed, the limestone is transported along a conveyor belt to the next stage of the process. The conveyor belt system is designed for durability and efficiency, ensuring smooth and continuous material flow.

5. Vibrating Screen:

• The crushed limestone is then passed through a vibrating screen, which separates the material into the desired size fractions (8mm, 20mm, 32mm, 50mm, and 85mm). The vibrating screen ensures precise sizing and removes any oversize or undersize particles, meeting the customer's specifications.

The stationary crushing production line for limestone, with its carefully selected equipment configuration, is capable of efficiently processing large volumes of limestone into multiple size fractions. The production line's design ensures high productivity, reliability, and precision, making it an ideal solution for various industrial applications requiring crushed limestone.

The focus of this project is the comprehensive utilization of tailings resources. The processed material is iron tailings. After crushing, the materials can be dry-selected to improve the resource recovery rate, reduce the cost of waste disposal, lower the cost of environmental governance, and achieve significant comprehensive benefits.

After careful comparison and consideration, the customer finally chose Liming's representative product, the NK mobile crushing station, as the core equipment to produce finished materials below 150mm. At the project site, the NK80J jaw crusher mobile vehicle has a small footprint, and the reasonable adjustable fixed leg design truly realizes foundation-free installation, ensuring "worry-free production" even on steep cliffs. Since it was put into production in 2022, the equipment on this production line has been operating well, with outstanding production capacity, continuously and steadily creating value for the customer.

Christmas is a holiday full of warmth and hope. On this beautiful day, the gorgeous transformation of Liming Heavy Industry's new core equipment adds more joy to this festive holiday.

Wish you a happy Christmas and a Happy New Year!
