the process of high-pressure grinding and the properties of its product are very different from those of conventional crushers or grinding mills, and the industry has learned to use this to its advantage in new applications. today, the iron-ore industry uses hpgrs to prepare pellet feed for finishing grinding after wet-ball milling and filtering.application of high pressure grinding rolls in an autogenous pebble milling circuit, in proceedings sag 2001 conference, vancouver, vol iii, pp 01. project magnet hpgrs online jan 2007
the high pressure grinding roll machine comprises a pair of counter-rotating rolls mounted in a sturdy frame. one roll is fixed in the frame, while the other is allowed to float on rails and is positioned using pneumo-hydraulic springs. the feed is introduced to the gap between the rolls and is crushed by the mechanism of interparticle breakage.using a high-pressure roller mill in the process of the grinding system can increase the production efficiency of the entire system by 20% to 30%. At the same time, the total power consumption of the grinding system can be reduced by to 50% compared with the conventional grinding method.
with industry demand for high pressure grinding rolls on the up, weir minerals is arguing that skewing is a vital feature for modern hpgrs to reduce wear, save downstream energy and ensure optimal grinding across the whole feed. the company was sharing its findings following the publication of 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.
high-pressure grinding rolls technology has struggled for acceptance into the hard-rock mining sector, has had many advances in this sector, but is still regarded as an immature At the same time, the uniform pressure profile in the milling gap results in better grinding and more even roller wear. this prolongs the service life of the rolls by up to 30%. through reducing the so-called bathtub effect the rolls need to be replaced less frequently and your hpgr pro will run longer with fewer downtimes.
