Grinding and separation efficiency of vertical roller mill were evaluated In addition to these performance figures of vertical roller mill and conventional closed ball mill circuit were compared
that of a vertical roller mill VRM carrying out the same oper ations by a factor of between 15 and 2 depending on the degree of optimisation of the ball mill Fig 1 illustrates this connexion as well as showing the increasing energy benefit that can be obtained with a vertical roller mill as the specific Blaine surface area rises
Nevertheless vertical mills also present certain disadvantages if compared to traditional grinding systems High pressures of the roller presses are required in case high Blaine values are desired and a significant amount of water has to be added in the grinding process in order to keep the
Vertical roller mills grinding an OPC of low fineness say around 3000 cm2g Blaine can operate without grinding aid but even when grinding to that low fineness grinding aid improves the output rate as well as the specific energy consumption Recent experience has shown that water has an effect similar to that of a grinding aid
The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials It is increasingly used as a solution for efficient grinding Within the cement industry vertical roller mills are becoming more important as more cement producers look to increase their use of clinker substitute
Therefore ease of replacement and regeneration is a major feature of the mill The MVR mill has a modern hydraulic system used in operation and for maintenance alike With this new type of roller suspension the rollers can be swung out of the mill in a controlled way – for ease of replacing the onepart grinding roller tires
achieved Blaine • very low differential speed between roller and grinding track • low specific wear during superfine grinding • hardfacing with mobile welding equipment possible All cement factory mills are now “vertical” and can be supplied by Loesche
• Tube mill with precrushing unit ie 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 Even though there are various types of systems available for cement grinding ball mills
