Ball Mill Roller Press for Cement Grinding Process
1. Roller Press Cement Pre Grinding System. The most noticeable feature of the roller press cement pre grinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required.

Roller mill. With a roller mill, a product is compressed and reduced between two counter-rotating rotating rollers. A major advantage of this process is that the proportion of fine particles (powders or dust) remains minimal compared to other grinding principles and that a nice homogeneous grain-size distribution is achievable.
