HPGR High Pressure Grinding Rolls

14/07/2016· Primary grinding in the high-pressure grinding roll increases the capacity of an existing dry ball mill operation. Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode. Hybrid grinding means that a part of the separator tailings (which are recirculated to the ball mill) is diverted and fed to the Polycom together with the fresh feed. Thus, some of the ...

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steelballs. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other e…
