Vertical roller mill for raw materials Climate

The power consumption level of vertical roller mill is lower than that of tube (ball) mill. The feed is ground between the disc table and the rollers which are hydraulically pressed against a disc table. The remaining time of raw materials in vertical roller mill is much shorter than that in tube (ball) mill; therefore, the crushing process and mixing process became more harmonized and this
