Vertical roller mills are one of the core items in cement plants and are used in particular for high and very high throughput rates. Up to six grinding rollers are suspended over a grinding plate. They form a parallel grinding gap and reach throughput quantities of up to 1400 t/h. The MVR mill is the latest variant in vertical mills and is thus ...
The breakage of a plate in a diaphragm entails repair work lasting several days and can even lead to the complete destruction of the entire diaphragm and thus stop production indefinitely. For this reason, grinding plant specialist Christian Pfeiffer developed the highperformance and reliable FLEXCORE technology plates.
A major technological aspect to control the grinding process is the mill ventilation. Several design criteria of a diaphragm have a significant influence on this important topic. In cement grinding the mill ventilation system fulfils two important functions: Cooling the cement and removing the heat generated during the grinding process.
