Client Challenges

• Hard Material Handling: Basalt’s high silica content (with plagioclase and pyroxene) demanded wear-resistant machinery.

• Multi-Size Requirements: Needed simultaneous production of 0–5mm sand and graded gravel for concrete and road projects.

• Environmental Compliance: Strict dust control required due to porous, abrasive basalt textures.

Liming’s Solution

1. Robust Crushing Circuit:

• Primary Jaw Crusher: Processed <700mm raw basalt blocks into 200mm chunks.

• Hydraulic Cone Crusher: Secondary crushing for uniform 20–40mm particles.

• VSI6X Sand Maker: Produced 0–5mm sand with <15% stone powder, ideal for high-strength concrete.

2. Eco-Engineering:

• Closed-loop dust suppression system reduced airborne particles to <8mg/m³.

• Noise-dampened enclosures for compliance with Thai industrial regulations.

3. Smart Grading: Multi-layer vibrating screens ensured precise separation of 0–5mm, 5–10mm, and 10–20mm products.

Results

• Zero Downtime in 18 Months: Tungsten carbide-lined wear parts extended component life by 40%.

• 20% Higher Profit Margins: Premium sand quality met JIS A 5001 (Japanese Concrete Standards).

• Regional Expansion: Client now supplies materials to Bangkok infrastructure projects and Malaysian port developments.
