Modern cement production relies on precision grinding systems to achieve optimal particle size distribution. The finish grinding stage typically employs vertical roller mills (VRM) or ball mills coupled with high-efficiency separators. Key equipment includes:
– VRM: Capacity 50-450 t/h, power consumption 22-40 kWh/t
– Dynamic Separators: Cut size 30-100μm, efficiency >85%
– Air Slide Conveyors: Width 400-1200mm, angle 3-6°
A complete aggregate processing line consists of:
1. Primary crushing (Jaw crusher: Feed size ≤1200mm, output 50-1500t/h)
2. Secondary crushing (Cone crusher: CSS 6-38mm)
3. Tertiary shaping (VSI crusher: Throughput 60-650t/h)
4. Screening (Multi-deck vibratory screens)
| Equipment | Key Parameters |
|---|---|
| Jaw Crusher | Max feed: 1200mm, Power: 90-315kW |
| Cone Crusher | CSS range: 6-38mm, Capacity: 45-1200tph |
| VSI Crusher | Rotor speed: 1500-3000rpm, Output size: 0-5mm |
Q1: How to control aggregate gradation?
A: Adjust crusher settings and screen mesh sizes systematically.
Q2: What’s the ideal moisture content for sand making?
A: Maintain below 3% to prevent VSI crusher clogging.
