In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.

Roller Press. Roller press consists of two rollers lined with wear resistant material. One roller is fixed and the other one is movable to exert pressure, applied hydraulically. A roller press looks similar to a roll crusher. However, the pressure exerted between rollers is very high - of the order of 400 kg/cm2 as compared to roll crushers.

While VRM 3.0 is newer than SCOR 9.0, VRM 3.0 in my assessment is more complete and more normalized in the sense that all domains (supply chain, customer relations, product development) are receiving equal attention from the Value Chain Group in the scope, integration and evolution of the model.
The tables in this section provide information about bearing tolerances, seat tolerances and resultant fits ().These should enable you to determine easily the maximum and minimum values of fits when using ISO tolerance classes for bearing seats and bearings with Normal tolerances for the bore and outside diameter.
bin above roller press and is reground by roller press. After separation by high efficiency separator, qualified product will be collected by bag filter and transported to silo. Disqualified product can, according to production requirement, partially or completely back to roller press or come into ball mill for re-grinding.
Roller press is a highly efficient communication system where the feed material is exposed under a very high grinding pressure between two solid rollers [ one fixed and one moving ] for a short time due to compression. The high pressure causes formation of micro cracks in the feed material and generates a substantial amount of the fine material.
There is no doubt that vertical roller mills offer significant advantages over ball mills regarding their energy efficiency. The specific energy consumption of a ball mill is greater than a vertical roller mill (VRM) that performs the same operations by a factor of between 1.5 and 2, depending on the ball mill's degree of optimization.
