used in mining applications for the last years, 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 and compresses the feeds density to 80% of its solid volume, exceeding its HR is a new generation high-pressure grinding roll that eliminates issues found in traditional hpgrs, allowing the mining industry to reach a new level of energy efficiency. the worlds largest hpgr was installed at freeport-mcmorans morenci site in arizona, usa.
ppern specialists in high-pressure comminution improved cost-efficiency high-pressure grinding roll presses are emerging as an important comminution technology in the minerals processing industry. the technology has found its key application in the liberation of diamonds and also in primary comminution.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 reduced energy consumption energy efficiency is key to running a profitable operation, so saving to 30% could pay huge dividends.
high pressure grinding roll technology is applied is a broadening range of applications. In the last few years, increasing numbers of hpgr units have been or are being installed in low-purity hematite was crushed with high pressure grinding roll, and effects of operating factors such as roller surface pressure and speed, and ore moisture content on size of crashed products
high pressure grinding roll is a newly crushing and grinding equipment with wide adaptability for fine and superfine material process. working together with the presetting crushing pressure, the two crushing rollers will be pushed in the opposite running directions by using the hydraulic cylinder with accumulator in order to ensure the high pressure grinding roll technology is applied to an increasingly diverse range of applications, predominantly iron, gold and diamonds. machine was operated at a high specific pressure of 4..0 nmm and the quartz content of the ore averaged near 37% rose et al 2002, dowling et al 2001, maxton et al 2006.
