Coal mill is the use of crushed stone at stone materials, stone blacksmith carried principle, in order to protect against wear and tear of equipment racks to be installed on the Coal mill liner, which protects the device, but also because the liner wear After you can always be replaced, without having to repair or replace equipment, thus extending the life of gangue grinder. Coal mill liners have two main functions, one of which is to protect the frame, which will help replace the large Coal mill, the other is on top of the liner are all teeth can be improved just crushed material crushing ratio. As the grinding process, different degrees of force all places, wear is uneven, generally the lower wear than the upper wear faster, for more prolonged use, the upper and lower liners are generally made symmetrical, gangue mill liner life depends on the material, the nature of the materials, operating parameters mill, feed uniformity and the like, and therefore, the medium-sized factory mill liner is usually selected high manganese steel, this material Once crushed material, which will increase the surface hardness, wear resistance is relatively increased, has a certain toughness, can withstand impact load. Meanwhile Large Coal mill size, enhanced hardness Coal mill work to strengthen and improve the mill's production capacity, expanding the application of market devices. Three high mechanical Coal mill liner with high wear-resistant manganese steel, you can better protect and crushing effect, with long time wear and impact resistance properties, so I chose three high mechanical Coal mill , to help you succeed it! 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 after a large price gangue grinder, 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, the assembly must maintain concentricity shaft assembly, calibration housings, hand drive shaft turn idle ease before they start testing, and pay attention 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, making it the material smoothly, reducing 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 roller screen large coal gangue grinder type, a small amount of coarse material return pulverized, in such a way to reduce the number of repair hammer, hammer prolong the service life.
