An energy-saving roller mill machine Description: This machine adopts roller main bearing structure, supported by a roller hollow shaft, the mill drive by the old-fashioned way of sliding friction into rolling friction. Reducing the consumption of wasted effort and improve production efficiency. Second, energy-saving roller mill: the occasional round ball mill is mainly composed of cylinder, supporting device, so that part of mobile devices and end seals and other components. Is supporting wheel cylinder mill matrix material crushing process is grinding inside it, was underway to move the role of transportation of materials. Cylinder unit is composed of rolling ring bearing, roller, gear wheel of three parts. The weight of the entire cylinder passed through the rolling ring roller, and roll the scroll wheel on the carrier ring, gear wheel cylinder axial movement of a barrier effect. Supporting roller mill gear including; motor, reducer, gear, ring gear and other parts out equipment and sealing devices. Third, energy-saving roller mill maintenance: repair process axial movement adjustment: the experience of riding wheel supporting roller ball mill working principle and structure characteristics and production maintenance, to ensure long-term safety equipment supporting roller mill operation, the key is to adjust the occasional round. Supporting roller mill maintenance linear axis; make the cylinder along the horizontal axis normal to be able to move back and forth, so that remains stationary gear wheel does not turn or make a short little movement of the force, so that each gear wheel, roller more evenly bear barrel load. Whether the observed relative position tire supporting wheel is still in the middle position; gear wheel force and rotation.
