Henan NF is the Ministry of Construction machinery manufacturers, with years of experience specializing in the production of mechanical products. The main products are: Series 3R, 4R, 5R Raymond mill, knife mill, ultra fine combination mill, ball mill, the winnowing grinder, dryer, jaw crusher, impact break, roll crusher, Sand and other types of milling equipment and mining equipment. The long ball mill work the problem how to solve? Measures to protect the Ball Mill, add a layer of what the back of the ball mill liners and cylinder liners, liner close to the cylinder wall, the wet milling of grinding media and slurry erosion in the lining and ball mill add a layer of plywood to do cylinder liner. Liner wear is severe, then the need for timely replacement of the lining of the tube mill, tube mill stopped grinding for a long time, the grinding media discharged, to prevent the cylinder caused by weight due to local deformation.In the mill commissioning bolt loosening, if not checked, will not take fastening measures into full production, loose the increase, in some parts of the mill will have a thin layer of material dissection, reducing the degree of connection of the steel bolt stress amplitude, coupled with the Mouth of the blocking material laminated difficult to eliminate, which accelerates the fatigue failure of the bolt, these should be noted. Screw loose ball mill in which the test machine, this situation is what happens? How to deal with, if the test machine which mill loosening, then must be the first time the screws tight, to avoid this phenomenon in the production process.
