  • Sanding, Sandpaper, Sponge & Abrasive Rolls: Amazon.com

    Sandpaper and sanding rolls are coated in an abrasive for a range of materialremoval applications, from coarse roughing to fine polishing. Its performance depends on the type of abrasive roll and its grit size. Aluminum oxide is one of the most common types because it can be used on a variety of material types, including most metals and wood.

    The technology's working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface.
