If one roller is rotating with N speed and the other is rotating with N1 speed, then we will get incomplete compression of the roller. Therefore, it is recommended to use the same speed for both the rollers. Types of Rolling Mills: Metal Rolling is classified into 5 types and they are as follows. Two High Rolling Mills; Three High Rolling Mills

The vertical roller mill (VRM), including powder separation and crushing subsystems, is used extensively for intermediate crushing of minerals in several industries such as cement, electric power, and chemical. Compression crushing is also the main crushing mechanism in the VRM, but there is also shear force between grinding roller and particles.

The High pressure grinding rolls (HPGR) developed by Schönert has been offered as a comminution technology with claims of improved performance relative to conventional grinding technology. In particular, it has been claimed that the advantage of the high pressure grinding roll is its lower specific energy consumption ( Schönert, 1979 ).

admin. High pressure grinding mill is a new type of grinding machine developed on the basis of highfine powder processing, also known as highpressure suspended roller mill. The product particle size can be adjusted arbitrarily within the target range of 80600, and the fine particle size can reach 1000 mesh.

In the High Compression Roller Mill the bed of material is subjected to determinate loading the intensity of which can be optimised to give a predictable particle size distribution. Although the system results in the production of agglomerated slabs the energy required for deagglomeration is proportionately low.

The typical product size range for these processes lies between D 97,3 < 200 μm and D 97,3 > 20 μm. However, there has been a recent development of market demand towards high throughputs in a t/h range with particle sizes of D 97,3 < 10 μm, with high performance concrete being a good example for such an application.. Due to these developing markets a reevaluation of the pendular roller mill ...

For comminution of finer particle size ranges (20mm > P 80 > 30 μm) machines like the ball mill, vertical roller mill, hammer mill, roller press or high compression roller mill, vibration mill, jet mill and others are used. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills such as the IsaMill are used.
