Otsuka’s andesite crushing plants are engineered for high-efficiency processing of hard volcanic rock into premium aggregates. The modular design integrates primary, secondary, and tertiary crushing stages with advanced screening technology.
– Primary Jaw Crusher (CGE Series): Feed opening 1,200×800mm, capacity 300-500TPH
– Secondary Cone Crusher (CC Series): Hydraulic adjustment, 250kW motor
– Tertiary Impact Crusher (CV Series): Rock-on-rock crushing, product shape optimization
– Multi-deck Vibrating Screen: 3/4/5 deck options with polyurethane panels
| Equipment | Model | Power(kW) | Max Feed(mm) |
|---|---|---|---|
| Jaw Crusher | CGE-400 | 160 | 900 |
| Cone Crusher | CC-1680 | 250 | 350 |
| VSI Crusher | CV-218 | 315 | 70 |
The plant produces precisely graded cubical aggregates:
– 0-5mm (manufactured sand) with ≤3.0 fineness modulus
– 5-20mm for ready-mix concrete
– 20-31.5mm for road base layers
Q: What’s the typical lifespan of wear parts?
A: Jaw plates last 6-8 months in andesite applications; cone mantles 4,000+ operating hours.
Q: Dust control measures?
A: Includes water spray systems at transfer points and baghouse filters.
Installed capacity: 450TPH
Final products: ASTM C33 compliant aggregates
Key achievement: Achieved 92% passing rate on cubicity tests
