2008-7-4 2. Grinding media The grinding media used are, generally, balls and cylpebs. In compartments of coarse and medium grinding are used balls, and in that of fine grinding, balls or cylpebs. In any compartment, sizes of grinding media must be correlated with the size of the material. Between the balls are formed free spaces (emptiness).

Grinding media contain balls of different sizes in designed proportions with large sizes in feed end and small sizes in discharge end. About 27 to 35 % volume of mill is filled with grinding media. Equilibrium charge is that charge where compensation for wear can be done by balls of one size only usually the largest size in the compartment.

2020-7-6 Grinding Media • The mill chambers are partially filled with steel balls having diameters ranging from 90 mm to 60 mm in 1st compartment and from 50 mm balls to 17 mm Ball in the 2nd compartment. Heat Generation • During grinding heat is generated in the mill which if not controlled would raise the temperature of and affecting cement quality.

2021-11-16 The second chamber is the fine grinding chamber. It is lined with classifying-type mill shell liners and provided with finer ball charge. Classifying liners ensure that the ball charge is segregated along the length of the chamber keeping larger grinding media at the beginning of the compartment and smaller media towards the end of the chamber.

2016-4-15 In the ball mills the material and the grinding media (spherical balls or cylpebs) are brought together in a rotating tubular compartment. The material and the grinding media are lifted some distance due to the rotation of the mill. During lifting, the material is ground by compressive and shearing action. After raising to a certain height, the ...

2017-2-20 All Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

2016-9-10 Thus, new design and operational alternatives should be searched to improve the grinding efficiency and to reduce the cement production costs. As mentioned, ball mills used in the cement industry are multi-compartment types. Different grinding media size distributions are applied in grinding compartments to increase the size reduction performance.
