The comparison of vertical roller mill and ball mill in . Traditionally, the closed circuit ball mill equipped with high efficiency separator has been the most widely used system for cement grinding.
The HPGR and air classification circuit used 20 – 30 % less energy than the HGPR, screen, ball mill circuit. While VRM was estimated to use 10 – 30 % less energy (depending on the type of VRM) than a ball mill circuit for a similar degree of comminution.
mill, where it again becomes part of the normal material circuit. The upgrade is an energy and space-effi-cient solution and in many cases providing a fast return on investment. Fast, easy installation A vertical roller mill capacity upgrade can be achieved without significant changes to existing machinery, so there's very little
Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed Attrition mill. The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling .

Separation operation of vertical-roller-mill will be modelled by application of current models. The model shall enable the prediction of the throughput, the particle size distributions around the vertical-roller-mill circuit, the specific energy consumption and in a later stage .
Within the power industry, vertical roller mills (VRMs) are the predominant equipment used for coal pulverisation. The essential requirements of pulverisation are grinding, heating, classification and transport of the pulverised coal from the pulveriser.
• Conventional tube mill - Open and Close circuit • Tube mill with precrushing unit i.e. vertical shaft impactor (VSI) or horizontal impact crusher (HIC) • Roller press in semi finish and finish grinding mode • Vertical roller mill (VRM) • Ring roller mill or Horo mill
Loesche is launching its new LM-Master for advanced vertical roller mill (VRM) control. This automation solution stabilises the VRM to allow operation with lower vibration. It also optimises mill performance by making accurate control actions several times per minute and offers continuous monitoring of the milling circuit for improved operational
tional ball-mill systems, high-pressure grinding rolls in every kind of design types and their various combinations with ball mills and, of course, VRMs vertical roller mills. All of these systems treat the material to be ground differently, in that the actual grinding needed to achieve the desired character-istics varies from one to the other.
