Vertical roller mills for iron ore grinding. Vertical Roller Mill Working Principle There are many different forms of vertical mill but the working principle is basically the same All these forms of vertical roller mill with the grinding roller or the equivalent of grinding roller grinding parts grinding roll along the horizontal circular motion on the disc the vertical pressure exerted on the
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
