Pakistan’s antimony ore reserves are primarily found in Balochistan and Khyber Pakhtunkhwa. To process this hard, brittle material efficiently, a tailored crushing and sand-making production line is essential. Here’s a breakdown of the ideal equipment configuration:
1. Primary Jaw Crusher: For coarse crushing (feed size: ≤750mm, output: 50-200mm)
– Model: PE600×900
– Capacity: 60-130t/h
– Motor power: 75kW
2. Secondary Cone Crusher: For medium/fine crushing (output: 10-30mm)
– Model: HPT300
– Capacity: 100-250t/h
– Hydraulic adjustment
3. Vertical Shaft Impact Crusher (VSI): For shaping and sand making (0-5mm)
– Model: VSI1140
– Throughput: 150-380t/h
– Rotor speed: 1700rpm
4. Vibrating Screens: Multi-layer screening (e.g., 3YK3070, 50-600t/h)
| Equipment | Model | Capacity (t/h) | Power (kW) | Output Size (mm) |
|——————–|———-|—————-|————|——————|
| Jaw Crusher | PE600×900| 60-130 | 75 | 50-200 |
| Cone Crusher | HPT300 | 100-250 | 220 | 10-30 |
| VSI Crusher | VSI1140 | 150-380 | 315 | 0-5 |
Q1: What’s the ideal moisture content for antimony ore crushing?
A: Below 5% to prevent clogging in VSI crushers.
Q2: How to reduce dust in the production line?
A: Install dust collectors (e.g., pulse bag filters) at transfer points.
Q3: Can this line produce graded aggregates for concrete?
A: Yes, by adjusting screen
