Roller mill - Wikipedia

Four-roller mills Four-roller mills have two sets of rollers. When using a four-roller mill to mill grain, the grain first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits. Flour is sieved out of the cracked grain, and then the coarse grist and husks are sent through the second set of rollers, which ...

High Pressure Grinding Rolls - 911Metallurgist

Unfortunately, high pressure grinding rolls continue to be confused with conventional roll crushers. HPGR comminution is substantially different from impact, attrition and abrasion comminution as it occurs in crushers, SAG and ball mills. The HPGR comminution occurs in a bed of particles between two counter-rotating rolls where only a limited amount of the ore is in contact with the rolls. The ...
