Figure 4 Example of a ball mill grinding plant with a HGG. External drying is required for an HPGR due to a limited amount of moisture permissible in the feed for size reduction. Vertical Roller Mills. In a vertical Roller Mill (VRM) interparticle comminution takes place in the filled gap between the grinding table and the rollers. 3
When grinding cement the ball mill has a yield of 300 1000g/t and the grinding system of the roller press has a yield of /t so it can meet the requirements of white cement. Low noise. The ball mill noise is above 110 dB while the roller press is about 80 dB.
Robust HRC™ high pressure grinding rolls (HPGR) 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
Far less studied is the effect of feed moisture. This paper investigates both the overall and the specific comminution efficiency of a circuit consisting of a pilot HPGR unit followed by a batch ball mill as a function of the moisture level in the HPGR feed. Forsterite olivine sand (−7 mm) supplied by Sibelco Nordic was used as feed material.
