For barite processing and sandstone aggregate production, a well-designed grinding plant integrates crushing, milling, and classification equipment to achieve high-purity powder (200-2500 mesh) and graded aggregates (0-5mm, 5-20mm).
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-120 | 75 |
| Raymond Mill | 4R3216 | 3-8 (325 mesh) | 37 |
| Vertical Shaft Impact Crusher | VSI-1140 | 60-140 | 250 |
| Trommel Screen | TDS-1540 | 100-200 | 15 |
1. Primary crushing: Barite ore → Jaw crusher → ≤150mm fragments
2. Secondary grinding: Raymond mill/Vertical roller mill → 90% passing 75μm
3. Aggregate shaping: VSI crusher → Cubic-shaped sand (<4.75mm)
4. Multi-layer screening: 3-deck vibrating screen → 5 grades of aggregates
Q1: How to control barite powder whiteness?
A: Use magnetic separators (>12,000 Gauss) to remove iron impurities before grinding.
Q2: Dust control methods?
A: Pulse bag filters (filtration efficiency ≥99.9%) with negative pressure systems.
