Takraf announced the receipt of an important project award for the supply of two High-Pressure Grinding Rolls (HPGRs) for a cement plant in Turkey The company's HPGR machines have been designed from the outset with maintainability in mind a clear target to achieve this goal is the reduction of downtime which includes integrated maintenance
similar to roller press around 20 % less compared to ball mill but with a moderate circulating load and grinding pressure This system claims to grind materials having moisture up to 20 % Thus in future mainly the VRM high pressure grinding rolls or Horizontal/ Ring Roller Mill shall be the acceptable propositions due to the simplicity of
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
Population growth and urbanisation have led to an increasing demand for building materials and in parallel there is a growing need for higher-capacity and more efficient cement plants In terms of cement grinding this has led to the development of more energy-efficient equipment such as the high-pressure grinding roll (HPGR)
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining The technology is now widely viewed as a primary milling alternative and there arc a number of large installations commissioned in recent years After these developments an HPGR based circuit configuration would often be the base case for certain ore types such as very hard abrasive ores
