Mining Technologies HPGR Pro – The next level in grinding

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.
