The ball mill is widely used in high-fine grinding machinery, energy-saving ball mill, a ball mill equipment, energy-saving ball mill liner is used to protect the cylinder, the cylinder from impact and friction of grinding media and materials directly, and also can be use of different forms of liner to adjust the grinding body's state of motion, in order to enhance the crushing effect of the grinding body materials, help to improve the efficiency of the energy-saving ball mill grinding, increase production and reduce metal consumption. Energy-saving ball mill liner wear, easier to install replacement should pay attention to the following eight issues;1 cylinder body should install liner grime cleaned.
Energy-saving ball mill installed liner should be coated with a layer of 1:2 cement mortar between the inner wall of the cylinder liner, and take advantage of the wet liner bolts tightened. The gap between the liner sand smooth pulp.
Fixed liner bolts should carefully pad good gasket to prevent leakage of slurry.
4, ball mill to install the liner should be preceded by checks and trimming of the liner, back and around smooth bolt holes should be thoroughly cleaned sand and clear casting burrs, the bolt smooth penetration. The north and around with wheel dresser, as appropriate, should reach the installation requirements.
5, directional liner should be noted that the direction shall not hold against. Long mill general compartment plate grinding cylinder separated into the two positions. The feed end of the first positions in the first positions for the ladder liner. Installation, ladder liner thin end the mill rotation direction consistent with the direction of the arrow. The compartment plate oliveri hole is tapered, and should be installed so the discharge direction of the cone mouth of the large end with the mill.
6 compartment plate is installed, you should put all the bolts, and then three times gradually tighten bolts. Also note that, should tighten the bolts on tight cylinder connecting bolts on the cylinder body center disc. Tighten all the bolts to bolt in the center of the cylinder body disc locking nut welding "spot welding".
7, the cylinder liner may not form an annular gap.
8, the cement the mortar solidified reached intensity requirements before they can be put to trial. Found running loose bolts should be tightened in a timely manner.
