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 rewelding of these roll surfaces.But,we have got a new way to solve this problem. This way the roll surface is coated and protected from the direct wear of the mineral rock.
  The autogenous surface generally prevents the larger rocks from a direct impingement on the roll surface,and provides a shield from the abrasive movement of material parallel to the roll surface. The wear thus becomes principally that of the hard metal studs,which are much more resistant. oof material,ceramic,etc.
