Conquer wet, viscous coal gangue with our Four-Roll integrated crushing circuit. Designed for zero-clogging production in any weather.
Coal gangue typically contains high moisture and clay content, making it notoriously difficult to process. In rainy seasons, traditional screening and crushing circuits suffer from severe clogging, forcing frequent plant shutdowns. The sticky nature of the material renders standard sieve plates useless, while high maintenance costs associated with clearing jams and replacing damaged screens severely throttle overall plant profitability.

Coal Gangue
Our Four Roller Crusher circuit completely redefines coal gangue processing by removing the need for screening, ensuring continuous flow regardless of moisture levels:
By eliminating screens, we remove the primary point of failure. Our system handles raw gangue with up to 30% moisture content effortlessly, ensuring uninterrupted production even during heavy rain.
The upper rollers provide coarse crushing, while the lower rollers perform fine grinding. This two-stage division of labor achieves the desired particle size (down to 0.1mm) in a single pass without any return-loop equipment.
• High Durability: High-chromium manganese steel rollers with on-site surfacing repair capability slash long-term spare part costs.
• Safety Protection: Integrated hydraulic or spring automatic retreat devices protect the unit from foreign objects often found in coal mine debris.
• Cost Efficiency: Simplified process means reduced site footprint and lower labor requirements for plant management.
• Flexible Power Options: Available in electric motor, diesel, or gasoline engine drives for remote site operations where grid power is unstable or unavailable.
