Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
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.
