A granite crushing production line is designed to transform raw granite into high-quality aggregates for construction, road building, and concrete applications. The process typically includes primary crushing, secondary crushing, screening, and sand making.
1. Primary Jaw Crusher
– Model: PE600×900
– Feed Size: ≤500mm
– Capacity: 50-160 t/h
– Power: 55-75 kW
2. Secondary Cone Crusher
– Model: HPT300
– Feed Size: ≤240mm
– Capacity: 90-260 t/h
– Power: 220 kW
3. Tertiary Impact Crusher (Sand Maker)
– Model: VSI6X1150
– Feed Size: ≤50mm
– Capacity: 200-400 t/h
– Power: 315 kW
4. Vibrating Screen
– Model: 3YK3070
– Screen Layers: 3
– Capacity: 100-500 t/h
1. Primary Crushing: Large granite blocks are reduced to ≤150mm by the jaw crusher.
2. Secondary Crushing: Cone crusher further crushes the material to ≤40mm.
3. Screening: Vibrating screens separate aggregates into different sizes (0-5mm, 5-10mm, 10-20mm).
4. Sand Making: The VSI crusher processes fine aggregates (0-5mm) into high-quality manufactured sand.
Q1: What is the output size range?
A1: Final products include 0-5mm (sand), 5-10mm, 10-20mm, and 20-40mm aggregates.
Q2: How to maintain the crushers?
A2: Regularly check wear parts (liners, blow bars) and lubricate bearings.
A granite quarry in Vietnam adopted this production line with a capacity of 300 t/h. The final products met ASTM C33 standards for concrete aggregates, achieving a 95% utilization rate of raw materials.
