The VPM series vertical pre-grinding mill is equipped with a grinding wheel and three rollers. The rollers are driven by a hydraulic cylinder to symmetrically rotate with high downward pressure against the grinding wheel, so as to shear, crush, and grind the feeding material on the wheel. If used with a ball mill together, it can create a cycled grinding system to fulfill pre-grinding, powder classifying and pre-grinding, as well as final grinding tasks. The electricity consumption can be reduced by 30%-40%, and the productivity can be increased by 50%-100%. Therefore, the pre-grinding machine is your ideal choice to achieve the high productivity and low energy consumption.
The vertical pre-grinding mill is primarily composed of the electric motor, speed reducer, grinding wheel, grinding roller, hydraulic system, and the lubrication system. The feeding material is firstly delivered to the middle of the grinding wheel. When the grinding wheel rotates, the materials are thrown to the grinding area due to the centrifugal force, and then are pressed and ground by the grinding rollers. Ground materials finally fall down to the lower chamber of the machine, and discharged with the help of a material scraper.
