The vertical roller mill is a kind of energy-saving and high-capacity grinding mill of environmental protection type. It can be used for grinding coal mine, cement raw material, cement clinker, power plant desulfurization lime powder, slag powder, blast furnace slag, manganese ore and other materials. The mill is suitable for many materials.
grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
roller mills (vertical air-swept grinding mills) since the sec-ond half of the 20th century. Loesche was and is the pio-neer of this technology. Hundreds of Loesche mills have been used in the cement industry across the world to the present day. They operate with two, three, four and six roll - ers.
As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
