Coal mill long-term production, will cause a lot of waste, such as dust or contaminants from entering the bearing housings inside, the dust will be fused with the lubricating oil in one, long-term effect occurs thick oil, if not cleared, then the long-term, will bring the bearing is worn. So to be cleaned regularly Coal mill, to avoid unexpected situation. Three high mechanical tell you how to conduct a comprehensive clean coal gangue grinder: 1, clean up when we must stop, and then take off the bearing box cover, use a clean brush to clean large picture gangue grinder to clean up the main target is a long-term production of residual oil and chunks of dust, then cleaned and re-greased before production. Two of the bearing box should be carried out finishing. 2, note the replacement seals. Long-term rotational friction bearings will happen, will happen friction high temperature, high temperature seals will cause distortion. Ring is plastic, so pay attention to replace the seals. Because the bearing seals are maintenance free from dust damage first step, we must do to prepare. Under normal conditions, the three will give customers high delivery several easy for customers to be replaced. 3, the dust around the bottom of the sieve should be conducted in a timely manner to eradicate major gangue grinder manufacturers, to avoid long-term accumulation, blocking sieve over the orifice. 4. For the rest, finishing it in accordance with the normal way you can reach the requirements. Coal mill maintenance and maintenance: 1. Three high mechanical impact hammer mill gangue part in the side of the wear and tear, you can exchange the other side to use. 2. Coal mill hammer wear on both sides, four adjustable hammer shaft on the rotor disk installation location (outward shift eye) after continued use. 3. When the hammer assembly or replacement, must maintain a balance of the rotor, the total weight of each row hammer hammer shaft should correspond to the total weight of the hammer shaft hammer equal, the total deviation of not more than 100g, single hammer The weight deviation not greater than ± 0.5kg. 4. Long-term use, if the replacement shaft, bearings, housings and other components of large gangue grinder, the assembly must maintain concentricity shaft assembly, calibration housings, hand drive shaft turn idle ease, before start the test, pay attention to the bearing temperature conditions. 5. If the raw materials because of factors, material into the spout cutting poor, the case is not a knot wall proposal may recommend a higher level in each group and try to remove the hammer cross. 6. As a result of material factors, the lower end of the discharge spout poor, crushed fine material in the cavity can not be spilled to repeat, so the lower the load is too large, it is recommended that the direction of the bottom piece spout abdominal lining removed, The spout expand 50-80 cm Large Coal mill uses the material to make it smooth and reduce the lower load. 7. discharge conveyor angle can not be too steep, should be less than 25 degrees. Out-feed conveyor speed limit should be greater than the feed conveyor line speed, so as to avoid the conveyor can not be promptly fines output, resulting in the accumulation chamber machine, increase the electrical load, but also to feed into the raw material does not stutter, even burn out the motor . 8. The machine does not grate the end of the wet material sticking to solve the problem, but the hammer wear between the liner and the gap is too large, the corresponding size will be thicker, it is recommended to install the discharge end of the conveyor drum sieve, will a small amount of coarse material return pulverized, in such a way to reduce the number of repair hammer, hammer prolong the service life.
