In some cases the Flapper Door sticks open allowing coal to blow back through the door. SAS Global designed a replacement kit that will eliminate the Flapper Assembly and problems associated with it. We call it the SAS Classifier Cone Extension Kit. The illustration shows the cone has been extended, forcing the coal to the center of the bowl.
· We have a rotary classifier which operates in 55 rpm, we have a vibration in pulverizer too, therefore we need to decrease the speed of classifier as low as 40 rpm, our fineness of coal after classifier is more than 70% passing mesh 200, I would like to know parameters like oulet temperature and air coal ratio in other coal plants ...
Powder Processing Machineries The offered range is designed in our welldeveloped manufacturing unit using superior quality raw material and the latest technology as per the set industry norms.
Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.

Rotary Classifier in Power Plant. Coal continues to play a predominant role in the production of electricity in the world. Coal Pulverizer is the one of the critical power plant component that is relied upon convert the energy stored in coal into electricity.
PURPOSE: To improve operation efficiencies at high load operations by bending the end of a rotary classification vane toward the rotary direction of a classifier. CONSTITUTION: In a classifier comprising a cylindrical rotary classifier shaft 14 rotating around a raw material feed pipe 2, a rotary classifier rotor 15 mounted on the lower end of the shaft 14, and platelike rotary classification ...
It is specialized in handling coal as it has been designed keeping in mind the parameters that need to be incorporated for effective handling. This coal is used for combustion in the steamgenerating furnaces of fossil fuel power plants. The Coal Pulverizer is well know for its features of low nitrogen oxide combustion systems. It is available ...
By adding a dynamic classifier to the pulverizers, you can better control coal particle sizing and fineness—and increase pulverizer capacity to boot. Keeping coalfired steam plants running ...

With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to % or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels .
Coal pulverizer design and operation is an important element integral to the long term success of Low NOx combustion systems. The increased use of Low NOx burners in the past 10 years has instigated a need for further development of coal pulverizer technology in an effort to ensure efficient operation of a power boiler for minimizing gaseous
Design of Pulverizers . Every coal pulverizer is designed with a particular fuel grinding capacity, or throughput, at a certain Hardgrove grindability index (HGI), based on moisture content, a defined raw coal size, and desired fineness level. These factors must all be considered and are significant in discussions of pulverizer capacity.
Williams Crusher leads the industry in coal pulverizer manufacturing, offering the industry''s most advanced direct fired coal and pet coke crushing system. Whether you''re looking for a direct fired pulverizer, lowcapacity coal size reduction solutions, or something inbetween, you''ll find it .
Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal,crushing and pulverizing it. Impact Mills Grinding Action is carried out by aseries of hinged or fixed hammers revolving in an Improving Coal Pulverizer Performance and Reliability Coal Conveyer Coal Crusher Raw Coal Bunker
The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fires. In most cases, pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air. Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire.
