Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough top-size media to grind the mill feed materials.
Re: Cement mill Residue. Dear Mr Jatin, You have not mentioned circuit of your mill.I assume that it might be a closed circuit cement mill. Best possible way to reduce residue on 45micron is by increasing circulation factor across the mill.The other way is to decrese cut size of your dynamic separator by increasing cage rotor speed.

Pre-grinding：it refers to adding a grinding machine in front of the cement ball mill to increase the output of the original grinding system by a large margin. This method features large investment and relatively complex process but it can increase the output of cement ball mill by up to 50%.
The size of the grinding media is calculated based on the grinding capacity of the mill and the size of the feed material. Because of the complex movement of the grinding media and the material in the mill, and because the actual production situation of each cement plant is different, it is difficult to determine a universally applicable grading rule.

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
