Crushing and Grinding. Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. In the nature minerals are usually intergrowth with other mineral species. In order to separate them, they must be unlocked through comminution (crushing and grinding).


Features of High Pressure Grinding Rolls. Designing lifetime of high pressure grinding rolls, guarantee 8000 to 12000 hours, for some ores can be used over 20,000 hours. Applied the high pressure crushing mechanism, the machine will have the higher crushing efficiency, lager crushing ratio and wider adaptability.


In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

processing is the most expensive process stage of beneficiation. One of the promising directions, which in some instances has enabled effectivization of ore pre-processing at operating plants, is redesign of an ore pre-processing circuit by introduction of high pressure grinding rolls as an auxiliary stage of fine crushing of ore before grinding.


The principle behind VIPER grinding is that the coolant is injected into the grinding wheel under high pressure ahead of the grind, and centrifugal force then moves the coolant out of the wheel during the grind, cleansing the wheel and cooling the material. The comparative results of VIPER are remarkable. The process saves time and money.
