WhatsApp: +86 18037808511Lower operating cost. Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency . With the Vertimill® simple and robust design, limited liner replacement is required.
WhatsApp: +86 18037808511Vertical roller mill. Vertical roller mill, also called cement vertical mill, it grinds raw materials by the movement between grinding roller, millstone and grinding device. In general the grinding efficiency of vertical roller mill is 80% as much power as cement ball mill, reduce about 30% power consumption. vertical cement mill.
WhatsApp: +86 18037808511Our customers have raved about the performance of our ceramic grinding media and our steel balls in vertical and horizontal mills like Chicago Boiler Red Head and Dyno mills. They also excel in Buhler/Drais, Netzsch, and Premier mills. And in MoorehouseCowles, Hockmeyer, and Eiger mills—just to name a few.
WhatsApp: +86 18037808511Vertical roller mills can have lower power than ball mills in most applications for dry grinding. One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when intergrinding different materials, the softer materials tend to be ground finer.
