A small jaw crusher and a sand making machine (also called a vertical shaft impact crusher or VSI crusher) are two different types of equipment used in crushing and sand production. Here’s how they work together in a sand-making process:
1. Small Jaw Crusher
– Function: Primary crushing of hard rocks (granite, basalt, limestone, etc.).
– Output Size: Typically 10–50 mm (adjustable).
– Usage: Breaks large stones into smaller pieces for further processing.
– Advantages:
– Simple structure, easy maintenance.
– High crushing ratio.
– Suitable for small-scale production.
2. Sand Making Machine (VSI Crusher)
– Function: Crushes smaller stones into fine sand (0–5mm).
– Working Principle: Uses high-speed rotor impact to break rocks into sand-sized particles.
– Advantages:
– Produces well-shaped, high-quality artificial sand.
– Adjustable fineness for different applications.
– Can be used for shaping aggregate.
Combined Process for Sand Production
1. Primary Crushing – Small jaw crusher breaks large rocks into smaller pieces (~30–50mm).
2. (Optional) Secondary Crushing – A cone crusher or impact crusher may be used for further reduction (~10–20mm).
3. Sand Making – The VSI crusher processes the crushed material into fine sand (0–5mm).
4. (Optional) Screening & Washing – Removes excess dust and improves sand quality.
Applications
– Construction sand for concrete, mortar, asphalt.
– Artificial sand for landscaping and industrial use.
– Small-scale mining and quarrying operations.
Recommended Setup for Small-Scale Production
| Equipment | Model Example | Capacity |
|———–|————–|———-|
| Small Jaw Crusher | PE 250×400 | 5–20 t/h |
| Sand Making Machine | PLS-700 | 10–30 t/h |
