Coal Crusher

What is a Coal Crusher?

A coal crusher is a machine used to crush large coal lumps into smaller sizes suitable for handling, storage, or further processing. It is widely used in power plants, cement plants, coal handling plants, and mining industries.

 Types of Coal Crushers

1. Hammer Crusher
   • Uses high-speed rotating hammers
   • Best for medium hardness coal
   • Produces fine output
2. Roll Crusher (Double Roller Crusher)
   • Two rollers rotate in opposite directions
   • Suitable for controlled size output
   • Less dust generation
3. Jaw Crusher
   • Heavy-duty crushing
   • Used for primary crushing
   • Handles large coal lumps
4. Impact Crusher
   • Uses impact force
   • High reduction ratio
   • Good for uniform particle size

 Working Principle

• Coal is fed into the crusher through a hopper or feeder
• Crushing happens by impact, compression, or shear force
• The crushed coal passes through a screen or grate
• Output size depends on crusher type and setting

 Key Features

• High crushing efficiency
