What is a high pressure grinding roll?
High pressure grinding rolls (HPGR) are used for size reduction of 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. High pressure grinding roll used in mineral processing, electric power, chemical industry, cement, refractory materials, abrasives, construction and other industrial sectors, for the fine crushing of high and medium hardness of ore and industrial slag, especially in building materials, electric power industry has been widely used.
High pressure grinding roll processed material
1.Medium grinding, fine grinding and superfine grinding of loose materials.
2.In mineral processing industry, HPGR can be arranged in front of the ball mill, or can be used as pre-grinding equipment, also can be combined with the ball mill to form a mixed grinding system.
3.Oxidized pellet industry, can replace the commonly used embellishing mill.
4.Building materials, refractory and other industries, for cement clinker, limestone, and bauxite, etc.
High pressure grinding roll features
1.The production capacity is up to 1000 t/h, which can increase the production of the whole system by 30% ~ 40%.
2.Compared with cone crusher, rod mill and ball mill, energy consumption is reduced by about 20 ~ 50%.
3.The grinding power consumption of the crushed materials is reduced to 15 kW/t.
4.The grinding effect is good, the content of fine powder below 1 mm is increased by 40% ~ 50%.
5.Small area, high reliability, operation rate can reach about 95%.
