Cement Ball Mill
Cement Mill Introduction:
High-efficiency cement mill is mainly used in grinding raw materials and final products in cement plant. And it is also suitable for grinding various ores and other materials in metallurgy, chemical, and power industry, etc. In our company, this machine has increased the productivity greatly, and the specific surface area is large, it is a new energy-saving grinding equipment, which has realized high capacity and super fine. Compared to internationally stipulated ball mill with same specifications, under the other situation of the same parameters, the output per machine hour has increased by 20%, and the power consumption per unit product has decreased by 10-15%. For open-circuit grinding, the specific surface area of cement can reach above 320㎡/kg. Besides, the performance of this machine has reached international advanced level, and it is suitable for close-circuit grinding, together with separator.

How cement ball mill work A cement ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the cement ball mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. Cement ball mill structure:
cment ball mill structure introduction:Cement ball mill is usually divided into at least two chambers,(Depends upon feed input size presently mill installed with Roller Press are mostly single chambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25mm in diameter). Ball diameter here is in the range 6080mm. In a two-chamber cement ball mill, the media in the second chamber are typically in the range 1540mm, although media down to 5mm are sometimes encountered. As a general rule, the size of media has to match the size of material being ground: large media can't produce the ultra-fine particles required in the finished cement, but small media can't break large clinker particles.
