Coal Crusher
Single Disc (5 No.)
Engineered for precision and consistency, this Single Disc Crusher effectively pulverizes coal into fine granules below 2mm. Featuring a robust 12mm body and 6 Manganese Steel hammers, it is ideal for coke oven applications.
Engineered for Tough Environments
The Manual Tools Company Single Disc Coal Crusher utilizes a unique high-speed impact action that is highly effective for reducing coal to specific sizes required for coke ovens and thermal power plants. Unlike traditional hammer mills, the single disc design minimizes the creation of excessive fines (dust), ensuring a higher yield of usable product.
Constructed with heavy-duty fabricated steel housing and lined with wear-resistant manganese steel plates, this machine is built to withstand the rigorous demands of 24/7 industrial operation.

3-Stage Operation Cycle
Gravity Feed Intake
Raw coal lumps (up to 125mm) enter via the top hopper. The angled chute design ensures material is directed straight into the rotor's impact zone without clogging.
High-Velocity Impact
The Single Disc rotates at 960-1440 RPM. Six suspended manganese steel hammers strike the coal against the serrated liner plates, achieving instant size reduction.
Calibrated Discharge
Crushed material passes through the bottom adjustable grate bars. Only particles smaller than 2mm are released onto the output conveyor, ensuring 100% uniformity.
Coke Oven Plants
Essential for preparing fine coal charge for beehive and recovery type ovens to ensure uniform combustion.
Thermal Power
Used for pulverizing coal for Fluidized Bed Combustion (FBC) boilers to maximize thermal efficiency.
Brick Kilns
Generates consistent fine coal dust required for automated kiln firing systems and mixture.
Daily / Weekly Checks
- Check foundation bolts for tightness before starting.
- Inspect V-Belts for proper tension and alignment.
- Ensure the crusher chamber is empty before motor startup.
- Monitor bearing temperature during operation (should not exceed 70°C).
Periodic Replacement
- Hammers: Inspect every 300 hours. Rotate faces if edges become rounded.
- Liner Plates: Check wear pattern monthly. Replace if thickness reduces by 60%.
- Rotor Disc: Inspect annually for any hairline cracks or imbalance.
- Bearings: Flush and replace grease completely every 6 months.
