The processing of coal ash and limestone clinker into high-quality sand and aggregates requires specialized crushing and sand-making equipment. This production line is designed to transform industrial by-products into valuable construction materials, optimizing resource utilization.
The core equipment includes:
1. Jaw Crusher (Primary Crushing)
– Feed size: ≤750mm
– Capacity: 50-800t/h
– Power: 55-250kW
2. Impact Crusher (Secondary Crushing)
– Max feed size: 500mm
– Capacity: 60-400t/h
– Rotor speed: 800-1200rpm
3. VSI Sand Maker (Tertiary Processing)
– Throughput: 60-520t/h
– Max feed size: 50mm
– Finished product shape: Cubic
4. Vibrating Screen (Multi-layer Grading)
– Screening layers: 2-4
– Mesh size: 3-80mm adjustable
