Coal Crusher & Rotary Valves in Coal Handling Systems
Coal remains a major industrial fuel source in India for power plants, boilers, and process heating systems. To ensure smooth combustion, coal must be accurately sized and conveyed — and that is where coal crushers and rotary airlock valves play a vital role.
At SHREE TECHNO ENGINEERS, we support coal handling industries by providing heavy-duty rotary feeder valves, direct-drive rotary valves, and industrial rotary airlock valves, engineered for dust-tight feeding and discharge.
What is a Coal Crusher?
A coal crusher is a machine used to break large coal lumps into smaller pieces suitable for combustion in boilers or feeding in material handling systems. Crushing helps in:
Improved combustion efficiency
Uniform fuel size
Better storage and transport
Reduced ash generation
Types of Coal Crushers Used in Plants
1. Jaw Coal Crusher
Ideal for primary crushing of hard coal lumps.
2. Hammer Mill Coal Crusher
Used for medium-hard coal, efficient for fine crushing.
3. Ring Granulator
Most common in power plants; crushes coal through impact and rolling.
4. Roll Crusher
Crushes by compression, suitable for sticky and wet coal.
Role of Rotary Valves in Coal Crushing & Handling
In modern coal handling systems, rotary valves are used to:
Maintain airlock between conveying systems
Regulate discharge of crushed coal
Control dust and air leakage
Feed material at controlled rates
Where Rotary Airlock Valves Are Installed
Below crushers
At dust collection points
Under cyclones and bag filters
In pneumatic conveying lines
