Raymond mill is a new type of high-efficiency pulverizing machinery and equipment, which has the production advantages of energy conservation and environmental protection. It has good processing performance for non-metallic ores such as marble, limestone, dolomite and calcite with Mohs hardness below 7. Efficient processing and utilization can bring good market benefits to enterprises. How to maintain the marble calcium powder processing equipment to extend its service life? Fodamon engineer summarized as follows:
A. During the use of Raymond mill, there should be fixed personnel to take care of it, and the operators must have a certain technical level. Before the installation of the mill, the operators must receive necessary technical training to make them understand the principle and performance of the mill and be familiar with the operating procedures.
B. In order to ensure the normal operation of Raymond mill, the “safe operation system for equipment maintenance” shall be formulated to ensure the long-term safe operation of the mill, and necessary maintenance tools, lubricating grease and corresponding accessories shall be provided.
C. After Raymond mill has been used for a period of time, it should be overhauled. At the same time, wear parts such as grinding roll, grinding ring, blade, etc. should be overhauled and replaced. Before and after the use of the grinding roll device, the connecting bolts and nuts should be carefully checked to see whether there is looseness and whether the lubricating grease is sufficient.
D. When the grinding roll device has been used for more than 500 hours and the grinding roll is replaced again, all rolling bearings in the roll sleeve must be cleaned, and the damaged parts should be replaced in time. The oil filling tools can be the manual oil pump and grease gun.
E. Add oil to the grinding roller bearing every shift, the central bearing of the main engine every 4 shifts, and the blower bearing every month. The maximum temperature of the bearing chamber shall not exceed 70 ℃. If the bearing is found to be overheated, remove and clean the bearing, bearing chamber and other accessories for once.
Careful maintenance of marble calcium powder mill can prolong the service life of marble calcium powder mill and reduce the comprehensive investment cost of enterprises.
