Optimization of Cement Grinding Operation in Ball Mills
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.

Ball Charge and Grinding Efficiency
The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls.

Effect of Grinding Media Charge on Mill Power Draw kW
Maximum power is drawn by a mill when the charge occupies approximately 50% by volume. The power curve becomes very flat in the range above 45%. As a result, mills are seldom run with charge levels greater than 45%. In rod mills, the charge is swollen by particles of feed which separate the rods.

How to Choose the Correct GRINDING MEDIA
General rule #1: Feed particle size should be 90% < 10x bead size. Example: 2.0 mm bead will have a feed size of 90% < 200 micron. General rule #2: final particle size will be 1/1000th of media size. Example: 2.0 mm bead will give a D50 of 2.0 microns.

BALL MILL GRINDING MEDIA
Grinding Cylpebs For Ball Mill. Grinding cylpebs is a type of grinding media with a short cylindrical or truncated conical shape. Just like the grinding ball, it can also be divided into the metallic type and non-metallic type.In large-sized industrial ball mills, we mostly adopt metallic grinding cylpbebs which include cast steel cylpebs and forged steel cylpebs.

Raw Material Drying-Grinding
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.

Grinding ball data
The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material, a protective coating of ground material covers the mill liners and grinding balls. It is known that cement raw material is much less abrasive than cement clinker.
