the ball mill coal pulverizing system

  • Pulverizer Wikipedia

    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.

  • Types of Boiler Coal Pulverizers Bright Hub Engineering
    Attrition TypeImpact and Attrition TypeImpact Or Hammer TypeCoal feeds onto a steel rotating table. Tapered, cylindrical, or spherical rollers on top of the table, under spring pressure, exert force on the coal particles on the table. When the table rotates, the coal passes between the rollers and the table and gets ground due to attrition. The hot air under pressure carries this ground coal upwards. Larger particles fall back to the grinding table. These coal particles then pass through a classifier where the large particles get separated due to cent...
