Indonesia’s growing infrastructure demands high-quality manufactured sand for housing projects. A typical sand crushing and screening plant includes primary jaw crushers, secondary cone crushers, tertiary VSI crushers, and vibrating screens. Key equipment parameters:
| Equipment | Model Example | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-160 | 75 |
| Cone Crusher | HPT200 | 90-250 | 160 |
| VSI Crusher | B9100SE | 150-350 | 250×2 |
| Screening Machine | 3YK2460 | -300t/h processing capacity-, 3 decks screen mesh sizes (5mm/10mm/20mm) |
Basalt and limestone are common raw materials in Indonesia. For hard rocks (>200MPa compressive strength), multi-stage crushing with cone crushers is recommended. River pebble processing requires VSI crushers to achieve cubical grain shape (flakiness index <15%). Moisture content above 3% necessitates pre-screening.
A Central Java plant processes 500tph of andesite into 0-5mm M-sand meeting ASTM C33 standards. Configuration:
1. Primary: JC443 jaw crusher
2. Secondary: GP300S cone crusher (closed-side setting 25mm)
3. Tertiary: CV218 VSI (rotor speed 55m/s)
Final product gradation: 4.75mm sieve passing rate 95%, fineness modulus 2.8.
A:*How to reduce VSI wear parts cost?* Use cascade feeding and maintain proper rotor speed (±10% of design value).
A:*Optimal screen mesh combination?* For concrete sand
