• 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 Mill speed 15.2 rpm GM in I chamber 107 t Critical speed 76 GM in II chamber 217 t.Grinding principle of vertical roller mill is the use of 2 ~ 4 rollers to the disc, as the speed of rotation the ground material, basically belongs to the material layer grinding. The material is mainly due to the rolling action of grinding roller and grinding in the mill, the grinding roller and disc rotation speed difference between, so has.
The differential pressure of the vertical roller mill is generally controlled at 5000~7000Pa to ensure the proper air volume. The change of the pressure difference within the mill is mainly affected by the feed amount when other conditions are constant. Therefore, the feed amount should be stabilized. Vibration of Verticle Roller Mill.Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.
