A simple machine crusher forms the backbone of sand and aggregate processing lines. Typically composed of a jaw crusher (primary crushing) and cone/impact crusher (secondary crushing), this setup efficiently transforms raw rock into graded materials.
| Equipment | Model Example | Capacity(t/h) | Feed Size(mm) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-120 | ≤500 |
| Cone Crusher | PYB-1750 | 115-320 | ≤215 |
| VSI Crusher | VSI-7611 | 60-180 | ≤50 |
| Vibrating Screen | 3YK-1860 | -80t/h per deck | -NA- |
1. Primary crushing reduces large rocks (<500mm) to medium size (<150mm)
2. Secondary crushing further reduces material to ≤40mm
3. Screening separates aggregates into required sizes
4. Tertiary crushing (optional) produces manufactured sand via VSI crushers
Q: What’s the minimum setup for small-scale production?
A: A mobile jaw crusher + cone crusher combo can process 50t/h with footprint under 200㎡.
Q: How to control final product shape?
A: Cone crushers produce flaky aggregates while VSI crushers create cubical particles ideal for concrete.
A granite processing plant in Malaysia configured:
– Primary: JC463 Jaw Crusher (120t/h)
– Secondary: HST315 Cone Crusher
– Tertiary: VSI1145 sand maker
Achieving daily output of 2500 tons with products meeting ASTM C33 standards for concrete aggregates.
