The wear parts within our High Pressure Grinding Roll are long-lasting, but also very easy to replace when they do wear down. Up to 20-30% reduced energy consumption Energy efficiency is key to running a profitable operation, so saving 20 to 30% could pay huge dividends.
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 grain size.
Used in mining applications for the last 30 years, High Pressure Grinding Rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.
Jun 03, 2020· Unlike rod or ball mills, high pressure grinding rolls reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other. There are no rods or balls that need replacing and it reduces energy consumption by about 40 percent for certain ore
High Pressure Grinding Mill Grinding. JOYAL High Pressure Mill is an improved type of Raymond mill. The purpose of the this kind mill is to grind non-flammable and non-explosive materials in the fields of building materials, mining, metallurgies and chemical industry with hardness less than 9.3 in Moh’s scale and humidity less than 6 percent.
High-pressure grinding roll was considered to have great potential in improving capacity and reducing energy consumption in a grinding circuit [45]. Comminution in the high-pressure grinding roll is the result of the high interparticle stresses generated when a bed of solids is compressed as it moves down the gap between two pressurized rolls.
