In the design of Raymond mill, the grinding media of different materials, rolls and rings, are selected according to the processing requirements of users. This will not only prolong the service life, but also increase the output. If users change their original intention and process other raw materials, they should replace the rollers and rings of other matching materials.
When users of Raymond mill change product fineness (especially when converting from low mesh to high mesh), they must pay attention to cleaning up the coarse powder and large particles adhering to the inner wall of classifier, pipeline, cyclone dust collector and finished warehouse, otherwise they are liable to cause large particle pollution. The cleaning method is usually to clean up the residual raw materials in the chamber and bellows of the mill, stop the main engine without feeding, adjust the classifier to the high speed of processing the corresponding fine powder, then turn the blower to a large speed, and start the wall vibrator on the finished warehouse, so that it can run for more than 4 hours empty, in which proper tapping of the pipeline and cyclone collection are required. The outer shell of the duster and the finished product warehouse is used to assist in removing the residual residue. Never be afraid of trouble and neglect this key process, especially in the production of ultra-fine powder with strict restrictions on large particles.
In order to ensure the purity of Raymond mill, it is necessary to strictly implement the sequence of starting and closing of each equipment on the production line. Ensure that the classifier that controls the fineness of the product starts first, and reaches the calibrated speed before starting other equipment (smoke-proof induced draft fan can start first), while in the case of shutdown, the classifier and induced draft fan will be shut down to prevent the inertia of blower after power failure from blowing large particles in the mill over the classifier causing pollution.
