It has the same working principle as raymond mill, but its grinding device is fixed with 1000 1500 kg pressure springs. when the machine works, the grinding roller, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of raymond mill given an identical condition and its output may increase 20% to high pressure grinding rolls 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 grain size.
