Grinding of mineral mixtures in high-pressure grinding rolls. (soft material) the roll surface is coated with a material film which increases the external friction between the material and the rolls. This effect causes more material to be drawn between the rolls and hence the gap to increase. Specific energy consumption as a function Grinding of mineral mixtures in highmaterial of roll in high pressure grinding roll,material of roll in high pressure grinding roll. High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grainmaterial of roll in high pressure grinding roll,material of roll in high pressure grinding roll.
