1. Raymond mill use in the process, there should be a fixed charge of personnel, the operator must have a certain level of technology. Before the installation of the mill operator must carry out the necessary technical training to understand the principle of the performance of the mill, familiar rules. 2, for the Raymond mill Raymond 3r7826 normal, should develop equipment "equipment maintenance safe operation of the system" can ensure the long-term safe operation of the mill, at the same time have the necessary repair tools and grease and the corresponding accessories. 3, Raymond mill after a period of time, you should repair 4r Raymond, while roller grinding ring blade overhaul replacement of wearing parts such as processing, grinding roller device before and after the use of the connection bolts and nuts should be carefully check to see if there is loosening, whether to add a little grease. 4, roller device use time more than 500 hours or so to replace the roller, the roller of each rolling bearing kit must be cleaned, damaged parts should be replaced, fuel pumps and hand tools available grease gun. 5, using a No. 1 MOS2 bearings are grease or sodium bitter ZN-2 grease lubricated bearings grinding roller 6. refueling once every shift, every host center bearing four classes plus a grinder, blower bearings per month plus one . Bearing temperature rise to a maximum of 70 ℃, found bearing overheating, should the breaking room cleaning bearings and accessories cleaned once. Feeding device, can effectively improve the utilization of equipment, ensure the stability of the milling process. Root feeding amount of adjustment can be changed by moving the shutter feed gap, or change feed roller speed execution. Mechanical feed material level automation systems are gravity-sensing regulator. Gravity Level sensor according to the profit and loss observed barrel material level, regulating feeding or feed roller shutter speed through the lever and pneumatic actuator to control the volume of feed. Whether feeding valves or other forms of fan-shaped, is by changing the cross-section of the feed gap control the volume of feed, the downside is that a large amount of adjustment of the gradient. 4r Raymond, Raymond Wuhu, Yuxin Senda Ltd.
