Ball Mills - an overview ScienceDirect Topics

The vertical mill has a proven track record in grinding blastfurnace slag, where it has the additional advantage of being a much more effective drier of wet feedstock than a ball mill. The vertical mill is more complex but its installation is more compact. The relative ‘installed’ capital costs tend to be site specific. Historically the installed cost has tended to be slightly higher for the vertical mill. 2.10.4 Particle Size Distribution

VRM - The Latest Technology - Bashundhara Cement

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.

Cement grinding Vertical roller mills versus ball mills

2020-3-23  High circulation factors invariably lead to steep particle size distribution curves, if the separation process is efficient. It has therefore been necessary to adapt special measures to reduce the inclination of the particle size distribution curve, in order to get a cement quality that is similar to the quality of cement ground in a ball mill.
