Abstract The results of industrial tests of ShKh15steel grinding balls with diameters of 25, 30, and 35 mm of 5th hardness group as per GOST (State Standard) at AO Kharkiv Pilot Cement Plant during grinding of cement in the second chamber of a cement mill are presented. It is shown that the use of ShKh15 steel grinding balls with small diameters to grind cement ensures grinding ...
The material may pass straight through the mill (opencircuit grinding), or coarser material may be separated from the ground product and returned to the mill for further grinding (closedcircuit grinding). Sometimes a small amount of a grinding aid is added to the feed material. For airentraining cements (discussed in the following section ...
In the early 90s, grinding in cement plants was operated mainly by vertical mills for raw material with rather good results in the majority of cases, and by tube mills for cement, with some ...

The "work horse" of the cement grinding plant is the twocompartment ball mill, commonly called the tube mill. Significant advances in model development were achieved in recent years ( Benzer et al., 2001, Benzer et al., 2003 ) through research on industrial scale.
As the name implies, in the batch mills, Fig., the charge of powder to be ground is loaded into the mill in a batch and, after the grinding process is completed, is removed in a batch. Clearly such a mode of operation can only be applied to mills of small or moderate sizes; say to mills of up to about 7 ft diameter by about 7 ft long.
Oversize Particles: Open circuit mills, whether separate ball and tube mills or compartment mills, always encountered the problem of tramp oversize in the product. A small percentage of clinker survived passage through the first grinding stage as particles—perhaps 1/16 in. diam—that were too large for the smaller balls in the following ...
Material is directly conveyed to the silos (silos are the large storage tanks of cement) from the grinding mills. Further, it is packed to about 2040 kg bags. Only a small percent of cement is packed in the bags only for those customers whom need is very small. The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships.
