Compared with the Raymond mill, the high-pressure suspension roller mill adds a high-pressure spring above the grinding roller. This unique design greatly increases the service life of the consumable parts of the mill, and the fineness of the finished product can be arbitrarily adjusted within the specified range.
The column mill is a vertical mill using high speed, medium pressure, and continuous, repeated grinding. It consists of the belt pulley, the gearbox, the main shaft, the feeding device, the discharging device, the spreading plate, the box casing, the roller, and the liner. The reducer device on the upper of the machine drives the
Currently, the system runs stably and the production capacity ranges between 530t/h and 550t/h, with power consumption of 11-13kWh/t. Backed by years of experience and in-depth knowledge within the field, CITIC HIC has successfully developed high pressure grinding roll (HPGR) suited to meet global customers' needs.
Brief introduction to high pressure grinding mill. High pressure grinding mill is suitable for high fine milling processing of non-flammable and non-explosive materials with Mohs hardness less than 9.3 and humidity below 6% such as barite, limestone, ceramic, slag; its finished product size ranges within 80-425 mesh.
