This is achieved with our HPGRs, thanks to the well engineered hydraulic pressing device in combination with the press control system.
 

    One of the most important subjects in HPGR is the wear of the roll surface. To date, most applications in the cement industry, have hard-faced smooth rolls, frequently with a hard-facing welded rim pattern on the surface for a better surface grip. high maintenance efforts — often requiring frequent rewarding of these roll surfaces. For this reason, we have find a new way to solve the problem. This way the roll surface is coated and protected from the direct wear of the mineral rock.
