Recently, especially from 1980s, grinding system using the vertical roller mill, which has effective grinding performance, is developed and applied in the cement grinding process. Descriptions . Basic equipment structure of the vertical roller mill for cement grinding is the same as the vertical roller mill of raw material and coal grindings.
The principle behind this structure was patented in 1970 and is employed for coal grinding mills and mills in the cement and industrial minerals industry. 2, 3, 4 or even 6 grinding roller con-figurations for a single grinding table can be realised. The first Type LM 26.3 D modular coal grinding mills were devel-

Vertical Roller Mill Working Principle. There are many different forms of vertical mill, but the working principle is basically the same. All these forms of vertical roller mill with the grinding roller (or the equivalent of grinding roller grinding parts), grinding roll along the horizontal circular motion on the disc, the vertical pressure exerted on the grinding roller through the outer ...
Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4 .H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4 ).
