A stone crusher business typically revolves around processing raw materials like granite, basalt, or limestone into aggregates for construction. Key equipment includes jaw crushers, cone crushers, impact crushers, and sand-making machines. These systems are designed for high efficiency, low maintenance, and adaptability to various raw materials.
Below is a parameter table for common crushing and sand-making equipment:
| Equipment | Model Example | Capacity (t/h) | Power (kW) | Max Feed Size (mm) |
|——————–|—————|—————-|————|——————–|
| Jaw Crusher | PE-600×900 | 50-120 | 55-75 | 500 |
| Cone Crusher | HP300 | 90-250 | 220 | 230 |
| Impact Crusher | PF-1315 | 100-180 | 200 | 350 |
| Sand Maker (VSI) | VSI-1140 | 60-180 | 250 | 50 |
Q1: What’s the lifespan of crusher wear parts?
A: Depending on material hardness, jaw plates and blow bars last 3-6 months; regular inspection is advised.
Q2: How to reduce dust pollution?
A: Install water spray systems or enclosed dust collectors at transfer points.
Q3: Can the line process wet clay materials?
A: A pre-screening or washing system is recommended to avoid clogging.
A granite processing plant in Malaysia adopted a 200tph production line with:
– Primary Jaw Crusher (PE-750×1060)
– Secondary Cone Crusher (HPT300)
– Tertiary VSI Sand Maker
Result: Achieved 45% crushed stone and 55% manufactured sand yield, meeting ASTM C33 standards for concrete aggregates.
For optimal performance, tailor equipment selection to material properties and output requirements. Regular maintenance ensures longevity and consistent product quality.
