India’s growing infrastructure demands high-quality sand and aggregates, with coal crushing machinery playing a vital role in processing raw materials. Modern plants integrate specialized equipment to transform coal waste into usable construction materials.
1. Primary Jaw Crusher: Handles large coal chunks (up to 1200mm feed size)
– Model Example: JC5460
– Capacity: 800-1200 TPH
– Motor Power: 400 kW
2. Secondary Cone Crusher: Produces intermediate sizing (25-60mm output)
– Model Example: HPC300
– Closed Side Setting: 10-50mm adjustable
– Throughput: 350 TPH
3. Tertiary Impact Crusher: For cubical shaped aggregates
– Rotor Diameter: Φ1300mm
– Final Product: 0-20mm with <10% flakiness
A typical 500TPH plant includes:
– Vibrating Grizzly Feeder → Jaw Crusher → Cone Crusher → Vertical Shaft Impactor → Vibrating Screens (3-deck) → Sand Washer → Stockpile Conveyors
Key Parameters Table:
| Equipment | Model | Capacity | Power |
|———–|——-|———-|——-|
| Jaw Crusher | JC5460 | 1000 TPH | 400kW |
| Cone Crusher | HPC300 | 350 TPH | 315kW |
| VSI Crusher | VSI1145 | 250 TPH | 440kW |
Q1: What’s the typical lifespan of wear parts?
A: Jaw plates last ~6 months, cone mantles ~4 months depending on abrasiveness.
Q2: Can the system process wet coal?
A: Requires pre-screening with specially designed grizzly feeders.
