Vertical Roller Mill (VRM) is the most advanced technology in cement production procedure. Bashundhara Cement has adopted VRM from LOESCHE, Germany in both the factories to ensure the best quality. With higher fineness achieved with VRM, it creates stronger and better quality concrete and thus, proves its superiority over other cement brand.

Output Capacity: 100 ~ 5,000 TPD. Grinding Mills: roller press / vertical roller mill / tube mill. Grinding Systems: open circuit / closed circuit / vrm final grinding. SEND INQUIRY. As a leading cement plant builder, AGICO offers an expert cement grinding plant EPC service.

The VRM for cement grinding offers a significant advantage in power savings. Typically, the VRM uses 50% less power than a ball mill when grinding the same clinker to 3900 Blaine. VRMs are also much more adept at handling hot feed compared to ball mills.The simple and compact vertical mill layout is cost competitive to build and offers many options for layout, …

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 delay …
