For dolomite quarry operations, selecting the right crushing and sand-making equipment is critical to achieving high productivity and consistent product quality. A typical dolomite processing line includes primary jaw crushers, secondary cone crushers, tertiary impact crushers (or sand makers), and screening systems.
1. Primary Crushing: Jaw Crusher (e.g., JC110)
– Feed Opening: 1100×850 mm
– Capacity: 150–300 t/h
– Power: 132 kW
2. Secondary Crushing: Hydraulic Cone Crusher (e.g., HPC300)
– Max Feed Size: 240 mm
– Capacity: 120–400 t/h
– Power: 300 kW
3. Tertiary Crushing/Sand Making: Vertical Shaft Impact Crusher (e.g., VSI6X1263)
– Throughput: 200–500 t/h
– Product Shape: Cubic, ≤5% needle content
| Stage | Equipment Model | Output Size (mm) | Capacity (t/h) |
|————-|———————–|——————|—————-|
| Primary | JC110 Jaw Crusher | ≤250 | 150–300 |
| Secondary | HPC300 Cone Crusher | ≤50 | 120–400 |
| Tertiary | VSI6X1263 Sand Maker | ≤5 | 200–500 |
Q1: How to reduce dust in dolomite crushing?
A: Use wet spraying systems or install bag filters at transfer points.
Q2: What’s the ideal moisture content for dolomite sand?
A: Below 3% for concrete applications; controlled via drying screens if necessary.
