The working principle of Raymond mill is that the grinding roller crushes the grinding ring, and the crushing effect is achieved by the combined action of the analysis machine and the fan, and the material is powdered once, and the fineness is adjusted conveniently. The Raymond mill is installed in a complete set. It is a sealed device. The design of the circulating air is that there is no air leakage in its pipe connection. The sealing requirements are very strict. Where there is a leak in the connection of the pipeline, the output will be affected, the equipment is prone to tremor, and the output will be reduced. And there is a more critical place of Raymond Mill, that is, the position of the discharge port, which must be tightly sealed and cannot leak air. This place sucks in the air. If the air leaks, the material will not come down and return to the working chamber of the host. Inside, this can easily cause blockage of the device. The operation of the Raymond mill should be maintained and operated by professional technicians. Before going to work every day, the equipment should be inspected. The several roller assemblies of the Raymond mill need to be refueled once a day. During the refueling process, the continuous inspection of the grinding roller Whether and the grinding ring need to be replaced, and whether there is a phenomenon of bearing damage. Regularly check whether the equipment screws are loose, check whether the dust bag of the device is breathable, and pat it once a day to keep the dust bag breathable. When the Raymond mill is cutting, the feeding must be uniform, and there can be no too much or too little cutting. Too much cutting can easily cause blockage of the equipment. Too little cutting will cause too much equipment noise.
