Vertical mill grinding materials to the mill

vertical roller millhas negative pressure design structure, according to the working principle of the grinding, grinding crushed material.Mill three is the main device installed in the grinding chamber pressure within the framework of the large cylindrical roller (roller), the framework is composed of thrust members and hinged joints, consist of three positioning bar of thrust roller pressure to the corresponding circular ring roller, hydraulic cylinder of the bottom of each rod/accumulator components, the function of the elastic to transfer pressure, make the grinding medium.And shock absorption buffer effect, reaction through the embedded frame structure steel, gear box and framework bearing pressure to the mill.

the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe. When the vertical roller mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the air flow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector.

Into the orbit of grinding materials to the mill, mill rotates, roller rolling pieces, and form a thick layer of mat, at the same time of the material being crushed along the grinding path around the radiant with outward.
Roller hydraulic tensioning force, the heavy pressure can increase the roller, roller role in grinding groove on the effective pressure 2 to 3 times.
