Coal Crusher
Double Disc (5 No.)
Engineered for high-volume industrial demands, the Double Disc Crusher delivers superior throughput of up to 25 TPH. Featuring 12 Manganese Steel hammers across two discs, it ensures rapid pulverization of larger coal lumps (<150mm) into fine <2mm granules for maximum combustion efficiency.
Double the Power, Double the Output
The Manual Tools Company **Double Disc Coal Crusher** is the powerhouse of our pulverization line. By utilizing a dual-rotor configuration, this machine doubles the impact frequency, allowing it to process significantly larger feed materials (up to 150mm) while maintaining the ultra-fine output required for Coke Oven Plants.
Ideally suited for large-scale operations, the unit is constructed with a 12mm heavy-duty fabricated steel housing and features 12 replaceable Manganese Steel hammers, providing exceptional durability against abrasive Indian coal varieties.

High-Velocity Crushing Cycle
Large Feed Intake
Capable of accepting larger lumps (150mm). The wide hopper throat ensures material distributes evenly across the width of both discs.
Dual Rotor Impact
Two discs rotating in sync carry **12 Manganese Hammers**. This creates a denser impact zone, pulverizing material faster than single-disc models.
High Volume Discharge
The crushed coal passes through the calibrated grate bars. The doubled surface area allows for a massive 25 TPH discharge rate while keeping size < 2mm.
Large Coke Ovens
Designed for high-capacity recovery type ovens requiring continuous feed without downtime.
Thermal Power
Critical for larger FBC boilers where fuel consistency directly impacts megawatt output.
Briquetting Plants
Provides the massive volume of fine dust needed for industrial fuel briquette manufacturing.
Daily / Weekly Checks
- Check tightness of all 12 hammer bolts.
- Inspect main shaft bearings for vibration (heavy load zone).
- Verify V-Belt tension (dual grooves require precise alignment).
- Clear magnetic debris from the hopper to protect liners.
Periodic Replacement
- Hammers: Inspect 12 hammers every 200 hours due to higher throughput.
- Liner Plates: Rotate side liners to ensure even wear patterns.
- Bearings: Use high-temperature grease; purge monthly.
- Grate Bars: Check for widening gaps that might allow >2mm particles to pass.
