The Bhuvaneswari coal mining project in Odisha, India, requires an efficient crushing and sand-making line to process overburden and produce high-quality aggregates. Here’s a tailored solution integrating core equipment and technical parameters.
1. Primary Jaw Crusher
– Model: JC4430
– Feed Size: ≤1,200mm
– Capacity: 400–800 t/h
– Power: 200 kW
2. Secondary Cone Crusher
– Model: HPT300
– Closed Side Setting: 19–51mm
– Capacity: 180–430 t/h
3. Tertiary Impact Crusher (Sand Maker)
– Model: VSI6X1150
– Max Feed Size: 60mm
– Output: 0–5mm (adjustable)
4. Vibrating Screens
– Multi-deck design (3YK3070) for precise grading.
| Equipment | Model | Capacity (t/h) | Power (kW) | Output Size |
|——————–|———-|—————-|————|————-|
| Jaw Crusher | JC4430 | 400–800 | 200 | ≤300mm |
| Cone Crusher | HPT300 | 180–430 | 250 | ≤51mm |
| Sand Maker | VSI6X1150| 150–350 | 315 | 0–5mm |
Q1: How to handle high-moisture coal overburden?
*A:* Pre-screening with heavy-duty grizzly feeders reduces clogging.
Q2: Can this line produce railway ballast?
*A:* Yes, by adjusting the cone crusher’s CSS to yield 40–70mm aggregates.
A similar setup deployed at Singareni Collieries (AP, India) achieved:
– Annual output: 3.2 million tons of aggregates.
– Sand recovery rate: ≥95% via VSI6X sand washers.
This modular design ensures low downtime and adapts to varying feed materials
