Diamond mining requires robust crushing and sand-making equipment to process raw ore into high-quality aggregates. A typical production line includes primary crushers, secondary crushers, sand makers, and screening machines.
1. Jaw Crusher (Primary Crushing)
– Capacity: 50-800 t/h
– Feed Size: ≤1,200 mm
– Power: 55-400 kW
2. Cone Crusher (Secondary Crushing)
– Capacity: 30-600 t/h
– Output Size: 5-60 mm
– Power: 90-315 kW
3. Vertical Shaft Impact Crusher (Sand Making)
– Capacity: 60-520 t/h
– Output Size: 0-5 mm (adjustable)
– Power: 110-400 kW
A standard diamond mining crushing line follows this flow:
Raw ore → Vibrating feeder → Jaw crusher → Cone crusher → VSI crusher → Vibrating screen → Finished aggregates (0-5mm, 5-10mm, 10-20mm).
Q1: What’s the lifespan of wear parts in diamond processing?
A1: Jaw plates last ~6 months; cone mantles ~4 months under normal conditions.
Q2: How to reduce dust in sand production?
A2: Install water spray systems or pulse dust collectors at transfer points.
Project: Botswana Diamond Mine (2023)
Equipment: PE750×1060 Jaw Crusher + HPT300 Cone Crusher + VSI1145 Sand Maker
Output: 200 t/h of high-purity silica sand for construction use.
For customized solutions, consult with engineers to match ore hardness and production targets.
