Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ( grindability ) is not always easy to predict, but large clusters of belite due to coarse silica in the feed.
Approximately 95 of the feed to the cement grinding circuit are clinker and the rest of the feed are additives which includes grinding aids. The sequence of operation takes place in Cement grinding mill is as shown in figure 1. Fig. 1 Process in Cement Grinding Mill.Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
The efficiency of the cement production depends greatly upon the efficiency of a grinding mill which consumes 60-70 of the total electricity consumption of the cement plant. A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder.A conventional cement grinding circuit is composed of a two compartment tube mill, a mill filter which collects the fine material inside the mill and a dynamic air separator where final product.
Recently-constructed cement plant is given with recommen-dations on proposed structural arrangement. A roller press is installed in front of grinding installations to cut down energy consumption in the grinding unit. Installa-tion of a roller press before rolling mill or cement mill in cement plants is now becoming a common feature.Cataracting cascading effect of grinding media charge. 4.
