Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.); when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, the …

The preliminary grinding is achieved by using a gyratory type of crushers whereas for fine grinding use is made of tube mills. The tube-mill crushers are generally provided with air separators through which material of desired fineness can only pass. The coarser, portion of the cement is fed back into the mill for further grinding.

11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these

Dry grinding mills, operating only in closed circuit, are used in dry and semi dry process cement plants. The hot kiln exit gas is used for drying the raw materials.

About 85% of the total energy expended in cement production is used for size – reduction; 75 % in grinding operation alone and 2 - 20 % of the energy supplied to the mill is used for size reduction, the remaining is lost in various activities such as friction between particles, friction between particles and mill elements, generation of heat and sound, vibration and material …
