Modern aggregate production relies heavily on efficient crushing and grinding equipment to transform raw materials into high-quality sand and stone aggregates. This article explores key machinery, process flows, and practical considerations for optimal performance.
1. Primary Jaw Crushers:
– Feed size: ≤1500mm
– Capacity: 50-2000t/h
– Typical models: PE1200×1500, CJ815
2. Secondary Cone Crushers:
– Output size: 19-38mm adjustable
– Hydraulic adjustment system
– Models: HPT300, CS660
3. Vertical Shaft Impact Crushers (Sand Makers):
– Sand yield: 30-50% of total output
– Fineness modulus: 2.6-3.0 controllable
– Models: VSI6X1263, B9100SE
Raw material → Vibrating feeder → Jaw crusher (coarse crushing) → Cone crusher (medium crushing) → VSI crusher (sand making) → Vibrating screen → Finished products (multiple specifications)
| Model | Max Feed(mm) | Capacity(t/h) | Power(kW) |
