HPGR High Pressure Grinding Rolls Weir
Substantially reduce your water consumption With their excellent throughput capacity, low maintenance requirements and energy efficiency, high pressure grinding rolls are fast becoming a go-to for greenfield projects looking to maintain their margins despite commodity price pressures and declining ore grades.
High-Pressure Grinding Rolls HPGR Manufacturers
Our HPGR Rolls utilizes the principle of high pressure inter particle comminution to grind various types of ore, industrial minerals, or clinker for cement production. Using our proprietary edge, stud and roll design and unique state of-the-art wear technology, a CSP HPGR Roll consumes less energy resulting in reduced operational costs and exceptional long term reliability.
(HPGR) high pressure grinding rolls/rollers for cement
High pressure roll grinding is normally used as super fine crushing process，which can be as the third or fourth stage of a crushing process, also can be used in the semi-autogenous grinding process for hard rocks. The input material size for HPGR normally is 20~60 mm，and output size can be less than 3mm. The best input size and output can
