Coal crushing is a critical process in mining and power generation, requiring robust equipment to handle abrasive materials efficiently. Modern coal crushers are designed to reduce large lumps into smaller, manageable sizes for further processing or direct use.

1. Primary Jaw Crushers:
– Feed size: Up to 1500mm
– Capacity: 50-2000 t/h
– Features: Heavy-duty construction, high reduction ratio
2. Secondary Impact Crushers:
– Output size: 20-50mm
– Capacity: 100-800 t/h
– Features: Adjustable breaker plates, hydraulic opening

3. Tertiary Cone Crushers:
– Final product: 5-20mm
– Capacity: 50-500 t/h
– Features: Precise particle shape control
A complete coal crushing line typically includes:
– Vibrating feeder
– Primary crusher (jaw or rotary breaker)
– Secondary crusher (impact or hammer mill)
– Screening system
– Conveying system
– Dust suppression units
