the five components user defined[6]. C15 transferred the raw materials to the vertical roller mill (VRM) as the raw materials should be finishground before being fed into the kiln for clinkering. This process is done in the VRM. The raw materials are simultaneously dried using hot air in order to get good quality cement.
LOESCHE Technology transfer Varying production demands to be fulfilled in one Loesche VRM Energy savings of about 30% Reduced operating costs through lower wear rates Simplified Process Chain Ore deposits are mostly heterogeneous and demand well adapted treatment Grinding is consuming over 50% of the energy in Mineral processing
• Vertical roller mill (VRM) • Ring roller mill or Horo mill Even though there are various types of systems available for cement grinding, ball mills are predominantly used machines for cement grinding in large number of cement plants. In this paper authors are covering the process diagnostic study of Ball mill for cement grinding. 2.
The entire cement manufacturing process producing up to 12,500 tons of clinker a day, requires superior performance and efficiency. The drive technology in use runs nonstop over more than 300 days a year, it also withstands the toughest environmental conditions. Siemens offers for all processing steps of the cement

: Cement is obtained by grinding various raw materials after . The degree calcination to which cement is ground to smaller and smaller particles is called fineness of cement. The fineness of cement has an important on the rate of hydration and hence on the rate of role gain of strength and also on the rate of evolution of heat.

Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. 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.
Vertical roller mill with peak raw, cement and slag grinding performance. Our costsaving Vertical Roller Mill (VRM) exhibits a modern design approach. We continuously improve our solution with the latest updates to enhance grinding performance and overall productivity.
