With the acceleration of the country's construction, it can be said that the investment in limestone grinding mill equipment is not worried about the market. The limestone grinding mill adopts a vertical structure, small footprint, simple and convenient operation, strong processing capacity, and other advantages, which are deeply loved by users. The grinding roller is the direct grinding part of the limestone grinding mill. If the grinding roller is severely worn, the efficiency of the limestone grinding mill will be seriously reduced. The editor here will briefly talk about how to choose and replace the rollers of the limestone grinding mill. I hope that it will be helpful to those who are using the limestone grinding mill.
 

The working principle of the limestone grinding mill is that the material is fed into the machine from the feeding hopper on the side of the machine casing, and it revolves around the vertical axis by means of the grinding roller device suspended on the plum blossom frame of the main machine. At the same time, it rotates by itself, due to the centrifugal force during rotation. , The grinding roller swings outwards and tightly presses on the grinding ring, so that the shovel blade scoops up the material and sends it between the grinding roller and grinding ring, and then grinds the material. As the main contact grinding parts with materials, the grinding roller and grinding ring will wear out to a certain extent during long-term use. The whole limestone mill is composed of the main equipment, analysis machine, blower, cyclone separator, air duct, and motor. The grinding roller and grinding ring are the main grinding parts of the main machine. It can be said that the grinding roller and grinding ring directly determine the working quality of the limestone grinding mill.

Generally speaking, it is necessary to replace the new grinding roller and grinding ring after 500 hours of use. The replacement of worn parts is also a Technical work needs to be completed step by step according to the instructions, otherwise rash and irregular disassembly may also cause accidental damage to the equipment. When replacing the grinding roller of the limestone mill, we should first disassemble the left side protective cover of the Raymond mill, the V-belt, and the double belt pulley on the roller shaft, and then remove the gear and the large and small gears on the right side of the machine. , Then pull down the rod spring to assemble, go to the lower grinding door, and remove the four bearing seat components, left and right, front and rear, then the grinding roller can be gently removed from the grinding door to complete the replacement.
