A Hammer Coal Crusher is a high-performance crushing machine designed to reduce large-sized coal into smaller, uniform particles suitable for combustion in industrial boilers and heaters. It works on the principle of impact crushing, where high-speed rotating hammers strike and shatter the feed coal against breaker plates and grates. This efficient crushing mechanism ensures consistent particle size distribution, which is critical for maintaining proper combustion efficiency, reducing unburnt carbon, and enhancing the overall thermal performance of boilers and heating systems.
The hammer crusher is especially suitable for soft to medium-hard coals such as lignite, bituminous coal, and sub-bituminous coal. Its rugged construction, simple design, and easy maintenance make it a preferred choice in fuel handling systems of power plants, process industries, and industrial heating applications.
Technical Highlights of Hammer Coal Crusher
-
Working Principle:
Operates on the principle of impact force; coal is fed into the crusher chamber and struck repeatedly by swinging hammers until it is reduced to the desired size and discharged through grates or screens.
-
Crushing Capacity:
Available in a wide range of capacities from 5 TPH to 200 TPH, depending on the size and hardness of coal.
-
Feed Size & Output Size:
-
Feed size: up to 200–300 mm (lumps).
-
Crushed output: typically 0–20 mm or as per boiler/heater requirements.
-
Rotor & Hammers:
Heavy-duty balanced rotor fitted with manganese steel or alloy steel hammers to withstand continuous impact and wear.
-
Material of Construction:
-
Housing: Cast steel or welded steel fabrication for durability.
-
Liners & breaker plates: Wear-resistant alloy steel for extended service life.
-
Drive System:
Driven by electric motor or gear motor through V-belts or direct coupling, ensuring reliable operation and high crushing efficiency.
-
Efficiency:
Ensures uniform coal size distribution, improving combustion efficiency and reducing slagging and fouling inside boilers and heaters.
-
Ease of Maintenance:
-
Quick opening body covers for inspection and replacement of wear parts.
-
Replaceable hammers and liners reduce downtime.
-
Safety & Dust Control:
Enclosed design with optional dust suppression system to minimize coal dust emissions and ensure safe operation.
-
Applications:
-
Fuel preparation for industrial boilers.
-
Coal crushing for thermic fluid heaters, hot air generators, and hot water generators.
-
Power plants, captive power units, and industrial heating systems.
✅ In summary: The Hammer Coal Crusher is a robust, energy-efficient machine that ensures consistent fuel size for reliable combustion in boilers and heaters. Its simple design, high crushing ratio, and low maintenance needs make it ideal for continuous industrial use.
