In thermal power generation and circulating fluidized bed boiler operations, coal feed particle size control directly affects combustion efficiency and boiler safety. Oversized particles cause poor fluidization and incomplete combustion; excessive fines increase fly ash carbon content and waste coal. Traditional hammer crushers processing power plant coal commonly suffer from wet coal clogging, high fines generation, and uneven particle size — failing to meet high-standard coal-fired production requirements.
For power plant coal feed crushing, Huashengming double-tooth roll crusher uses low-speed, high-torque shearing and splitting principles, making it the preferred equipment for retrofits in thermal power plants, self-provided power plants, and coking facilities.
Coal crusher for power plant
I. Power Plant Coal Feed Crushing – Pain Points of Traditional Equipment
Power plant raw coal has complex composition, mixed with clay and gangue, with unstable moisture content. Traditional impact-type equipment is inherently unsuitable for coal processing:
Severe over-crushing. High-speed impact generates excessive ultrafine coal powder that cannot be effectively burned, wasting coal, increasing fly ash carbon content, and adding load to dust collection systems.
Wet coal causes frequent clogging. Screen-equipped crushers face severe screen blinding and chamber sticking with wet and agglomerated coal during rainy seasons, requiring manual cleaning and disrupting coal handling continuity.
Uneven output particle size. Mixed particle sizes with oversized coal chunks entering the furnace cause poor fluidization and incomplete combustion, leading to carbon deposits and slagging that affect boiler safety.
High wear parts consumption. Gangue in coal accelerates hammer and liner wear, requiring frequent replacement, with persistently high maintenance and parts costs.

II. Huashengming Tooth Roll Crusher – Customized for Power Plant Coal Conditions
Huashengming double-tooth roll crusher is specifically designed for power plant coal handling systems. It uses low-speed, high-torque shearing and splitting principles with a screenless structure and selective crushing — fundamentally solving the problems of clogging, over-crushing, and particle size失控 in coal crushing.
More lumps, less fines, precise particle size control. The equipment follows the “crush only oversized lumps, preserve qualified particles” logic — no violent impact, no repeated grinding. Coal meeting the required size passes through directly; only oversized lumps are sheared and split. Over-crushing rate is significantly reduced. Output particle size is uniform and controllable, fully matching boiler feed standards. The furnace fluidizes more stably and burns more completely, effectively reducing carbon content in fly ash and saving fuel costs.
Screenless design + self-cleaning rolls – wet coal never clogs. Eliminating traditional screen plates, the equipment controls output precisely through the roll gap, completely preventing wet coal screen blinding and hole clogging. The two rolls rotate at different speeds, with teeth相互 scraping and self-cleaning — handling high-moisture raw coal, frozen agglomerated coal, and sticky muddy coal reliably. It operates unaffected by rainy weather, supporting 24/7 continuous coal supply.
Overload release protection for safer operation. Iron pieces and hard tramp materials are unavoidable in coal handling. The equipment is equipped with a hydraulic automatic release system that retracts and discharges hard objects, effectively preventing equipment jamming and component breakage.
Wear-resistant modular tooth sleeves for easy maintenance. The core crushing tooth sleeves are made of high-wear-resistance alloy material with excellent impact and wear resistance. The modular design allows localized replacement of individual tooth sleeves without complete disassembly — significantly reducing maintenance time and parts replacement costs.

III. Applications and Market Recognition
Huashengming double-tooth roll crusher is suitable for raw coal, coal with gangue, coke, and coal gangue, with feed size ranging from 80-1050mm and capacity covering 7-300t/h. The equipment has been widely used in power plants, coal mines, and coking facilities. With core advantages of stable particle size, minimal fines, no clogging, and low maintenance costs, it has become a reliable choice for coal feed crushing.
