Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

The Rotor Mill Pulverisette 14 is an allpurpose mill for rapid crushing of mediumhard to soft substances. Grinding temperaturesensitive materials is also possible with the variable speed rotor mill. The extremely high rotor speed enables fast and effective grinding, drastically reducing thermal stress on the grinding material.

This standardization enables selection of an appropriate mill for a specific duty. Ball Tube Mill The oldest pulverizer design still in frequent use. 25% to 30% of cylinder volume is filled with wear resistant balls of 30 60mm. The cylinder is rotated at a speed of about 20 rpm. Specific power consumption 22 kWh per Ton. Suitable for hard coals.

In the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone. The tube mills have a large circular drum, with adequate ball charge, which is rotated at about 70% of the speed at which the ball charge would be held against the inner surface by centrifugal force.

Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.

than normal, either when initating coal feed on mill startup, stopping coal feed on shutdown, or when equip ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent.

Explanation: Ball and race mill have greater wear compared to other pulverizers. The advantages of lower space occupied, lower power consumption in kW hr/ton of coal pulverized, lower weight and lower capital cost have outweighed the wear problem and these pulverizers found general acceptance.

The coal is fed into the ball mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverize the coal to particles. Coal particles are mixed with the hot air, which enters the mill through the air inlet, and are conveyed up to the classifier by the ...

12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.
