PVC high-speed mixer improves fluidity and reduces dust flying through powder granulation. The powder granulation can improve its solubility. Mixing granulating drying is completed in one machine. Use anti-static filter cloth and operate the equipment. The pressure relief hole shall be set to prevent personnel from being injured in case of explosion. The PVC high-speed mixer equipment has no dead angle, the loading and unloading of materials are light and fast, and the washing is convenient, meeting the “GMP” specification. High degree of automation, equipped with program control, analog screen display and other technologies for users to choose. Correct operation and maintenance of PVC high-speed mixer: 1.Adjustment of the gap between the ring mold and the press roll of the PVC high-speed mixer For the adjustment of the gap between the new ring mold and the press roll, the high point of the ring mold and the press roll should be slightly contacted, and the press roll should reach the “like to turn rather than turn” state. If the adjustment is carried out in the working state, the pressure of the ring die and the pressure roller can be increased appropriately, but it must be limited. The gap between the ring mold and the press roll is too large, and the press roll cannot rotate, resulting in machine blockage. If the gap between the ring mold and the press roll is too small, the wear of the ring mold and the press roll will increase, and the load will increase, which will seriously cause the mixing of the ring mold and the press roll. The clearance between the ring mold and the press roll shall be checked in time, and less once every four working hours. When adjusting each pressure roller, pay attention to the adjustment direction of each pressure roller. The sum of the torque of each pressure roller relative to the granulator shaft should be zero, so that the granulator is free from the influence of asymmetric force. 2.The team shall carry out pre shift inspection for the maintenance of the granulator every shift, check all transmission parts, instruments and valves, add lithium based lubricating oil, and remove iron filings from the iron ware. 3.The correct installation or replacement of the ring mold and press roll for the PVC high-speed mixer is generally that the new mold is equipped with a new roll, and the old mold is equipped with an old roll, so that the surface shape of the ring mold and press roll is close to the profiling state, and the local gaps between the ring mold and press roll are roughly the same. In this way, the stress and discharge of the whole ring die are very uniform, which can improve the production efficiency.
