KTM vertical mills are known for their very high grinding efficiency, as evidenced by their low specific consumption of electrical energy. They consist of the grinding chamber itself, where the material is comminuted in the layer between the grinding table and up to four runners, and an integrated dynamic separator that checks product fineness.
The Vertical Mill at Samarco operates in parallel with ball mills. The regrind is fed with the product from the rougher flotation of coarse and fine particles, with an approximate F80 of 120 m. The grinding circuit's product has a P80 of approximately 38 m. In the Vertical Mill, 15 mm diameter grinding balls of high chromium cast iron are used.
The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments
