Coal mill replacement of damaged parts gangue grinder model size, you need to order the dismantling, demolition, follow these steps: 1. Open the gangue grinder cover, remove the top of the spindle nut, then remove the grading impeller, in should be careful not to remove the collision grading blade, lest affect balance. 2. Remove the support rod, remove the split ring. 3. Remove the nut, remove the shredder disk. 4, need to clean or replace the bearing gangue mill bearings, from the bottom of the machine will be crushed out of the rotor assembly, on the table, remove the two pulleys respectively, ring and ring, then pull grader impeller shaft and spindle grinding, cleaning, checking bearings and seals. 5, to be demolished when the gangue grinder outstanding device should first remove the belt, loosen the bolts to remove the feeder. Several points gangue splintered machine maintenance: 1, Coal mill and power unit should be securely mounted. If long-term fixed Coal mill operation, it should be fixed on the basis of the cement; if the mill is the amount of money flowing Coal mill operation, the unit should be installed in the machine base is made with angle iron, and ensure power machine (Diesel or electric motor) and gangue crusher pulley groove in the same plane of rotation. 2. Coal mill after installation to check ministries fastening fasteners, if loose to be tightened. At the same time you want to check the belt tension is appropriate. 3. Coal mill before the start, the first rotation of the rotor by hand, check the tooth claw hammer and rotor operation is flexible and reliable, with or without shell collision phenomenon, the direction of rotation of the rotor is consistent with the direction of the arrow machine gangue grinder maximum yield, power machine and Coal mill lubrication is good. 4, it should not replace the pulley to prevent excessive speed so crushing chamber to produce an explosion, or the speed is too low affects the efficiency of coal gangue grinder. 5, after gangue grinder should start idling 2 ~ 3min, no abnormal phenomenon feeding after work. 6, work should always pay attention to the functioning of the gangue crusher, feeding should be uniform, to prevent clogging gangue grinder boring car, not a long work overload. If there is vibration, noise, bearing and body temperature is too high, the outside spray material and so on, should immediately stop inspection, troubleshooting can continue to work.
