Modern aggregate production lines rely heavily on crusher and screen machines to process raw materials into high-quality sand and stone aggregates. These systems are engineered for efficiency, durability, and precise particle size control.
1. Jaw Crusher
– Primary crushing for hard rocks (e.g., granite, basalt)
– Feed opening: 150×750mm to 1,500×2,100mm
– Capacity: 50–1,500 t/h

2. Cone Crusher
– Secondary/tertiary crushing with hydraulic adjustment
– Max feed size: ≤300mm
– Output gradation: 5–40mm adjustable
3. Vibrating Screen
– Multi-layer screening (2–4 decks)
– Screening accuracy: ±5% tolerance
– Power: 15–55 kW
A typical 200tph granite processing line:
1. Primary jaw crusher → 2. Cone crusher → 3. Vibrating screen (closed-circuit) → 4. Sand maker (for 0–5mm particles) → 5. Belt conveyors
Q: How to reduce dust in crushing plants?
A: Install water spray systems + enclosed conveyors + bag filters.
Q: What’s the lifespan of crusher wear parts?
A: Manganese steel jaws last ~500–800 hours; cone mantles ~300–600 hours depending on material abrasiveness.

Location: Texas, USA | Output: 450tph | Equipment:
– Primary gyratory crusher (60″x89″)
– Two secondary cone crushers
– Triple-deck screens
Result: Achieved consistent 0–5mm, 5–20mm, and 20–40mm fractions with <3% oversize material.
