Marble mining typically employs diamond wire saws or chain saws for block extraction, followed by crushing and grinding to produce sand/aggregates. Modern production lines prioritize dust control, energy efficiency, and particle gradation optimization.
1. Primary Jaw Crusher
– Model example: JC4632
– Feed opening: 460×320mm
– Capacity: 50-180 t/h
– Power: 55kW
2. Secondary Cone Crusher
– Model example: HPC220
– Max feed size: 235mm
– Capacity: 90-440 t/h
3. Tertiary Impact Crusher (for shaping)
– Model example: VSI1140
– Throughput: 120-260 t/h
– Rotor speed: 1700-1900 rpm
4. Vibrating Screen
– Deck layers: 2-4
– Screening efficiency: ≥90%
1. Coarse crushing → Medium crushing (with pre-screening) → Fine crushing → Sand making → Gradation adjustment → Finished product storage.
