Client Challenges

• Required 60–70cm granite boulders to be processed into 0–5mm sand, 5–10mm, and 10–20mm gravel.

• Existing systems struggled with dust pollution (exceeding 20mg/m³) and frequent maintenance.

• Needed a scalable, eco-friendly solution to expand production for international markets.

Liming’s Solution

1. Core Equipment:

• Jaw Crusher: Primary crushing of 70cm granite blocks.

• HPT Hydraulic Cone Crusher: Secondary crushing for precise grain shaping.

• VSI6X Sand Maker: Produced 0–5mm high-quality sand with <10% stone powder.

2. Eco-Friendly Innovations:

• Modular enclosed dust suppression system.

• Pulse bag dust collector reduced emissions to ≤10mg/m³ (below EU standards).

• Closed belt conveyors minimized noise and spillage.

3. Scalability: Added a dual-purpose line in 2024 to simultaneously produce sand and gravel.

Results

• 24/7 Stable Operation: Zero downtime in 2+ years, thanks to wear-resistant components.

• Emission Compliance: Dust levels cut by 50%, aligning with global environmental regulations.

• Market Expansion: Enabled client to secure contracts in Europe and ASEAN for premium aggregates.
