granite rock used for sand making

Granite Rock Utilization in Sand Making Production Lines

Granite, as a high-hardness igneous rock, is widely used in artificial sand production due to its excellent compressive strength (typically 100-300 MPa) and abrasion resistance. Modern crushing and sand-making lines transform raw granite into high-quality manufactured sand through systematic processing.

Core Equipment Configuration

The granite sand production line typically consists of:
1. Primary crushing: Jaw crusher (Feed size: ≤1200mm, Output: 50-800TPH)
2. Secondary crushing: Cone crusher (Max.input: 560mm, Adjustment range: 3-60mm)
3. Tertiary shaping: Vertical shaft impact crusher (Throughput: 60-650TPH, Product shape: cubic)
4. Screening system: Multi-layer vibrating screens (Screening efficiency: ≥90%)

Stage	Equipment Model	Input Size	Output Size	Capacity
Primary Crushing	PE1200×1500 Jaw Crusher	≤1020mm	150-300mm	400-800t/h
Secondary Crushing	HST315 Cone Crusher	≤560mm	≤70mm	215-610t/h
Tertiary Shaping	S5X1145 VSI Crusher	≤50mm	0-5mm adjustable	120-583t/h
Screening	S5X2760 Vibrating Screen

The Manufacturing Process Flow:

Raw granite undergoes coarse crushing → medium-fine crushing → sand making → screening → dust removal → finished product storage. The entire process achieves a closed-circuit circulation system with dust collection efficiency exceeding 99%.
