The vertical milling machine grinding principle is that the mill using 2 4 rollers close to the disc for medium speed rotating the ground material basically belong to the material layer grinding
• 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 used machines for cement grinding in large number of cement plants In this paper authors are covering the process diagnostic study of Ball mill for cement grinding 2
Firstly and as explained above the different grinding behav iour of the vertical roller and ball mill systems means that particles remain in a ball mill system for about 20 to 30 min utes before they leave the classifier as product
Performance Evaluation of Vertical Roller Mill in Cement Grinding Case Study ESCH Cement Plant But later as the operating principle of the equipment based on the compression some portion of
Vertical roller mill are suitable for huge capacity producing widely used in grinding nonflammable and nonexplosive materials under 93the Mohs hardness such as quartz feldspar calcite talcum barite fluorite iron ore copper ore quartz especially for slag cement clinker zircon sand fly ash and carborundum coal etc
Vertical roller mill has two classic models namely LM vertical mill and LUM ultrafine vertical roller mill Application Field according to the structure of LM series vertical mill it can be applied to the powder milling of cement electric power metallurgy chemical industry ore and other industries
Grinding and classifying The raw material is ground and dried in the mill Mills with 2 rollers have one hot gas entry channel while those with three and four rollers have two and mills with six rolls have four The process gas is distributed from there uniformly by means of guide vanes into the grinding bed chamber
