Maintenance elements of metal chip crusher

because the use environment of metal chip crusher is more complex, because of crushing some large, hard quality of material and metal ,the chip crusher itself has a certain impact, so it is necessary to maintain the metal chip crusher. the maintenance of the crusher should be carried out in accordance with the three elements, the following is to give you the three elements of the maintenance.
1. the screen is made of thin steel plate or iron plate punching. when the net is worn or damaged by impurities, if the damage range is small, you can choose riveting welding repair; if large-scale damage, should be replaced with a new screen. when assembling the new screen, the burr edge of the screen should be in, the sliding surface is outside, and the screen plate is closely combined with the screen frame. when assembling the ring screen plate, the rotation angle of the top of the connection should be done well to avoid the material stuck on the top of the connection.
2. the factory should clean the bearings after every 300 hours of operation. if the bearing is oil-lubricated, new oil can be added to fill at least 1/3 of the bearing seat gap, at least 1/2, and as long as the lid of the oil cup is slightly tightened before operation. when the crusher bearing is seriously damaged or damaged, it should be replaced immediately, and pay attention to enhance lubrication; when using tapered roller bearings, pay attention to the inspection of the axial gap of the bearing, so that it remains 0.2-0.4mm. in case of discomfort, increase or decrease the paper pad on the adjusting bearing cover.
3. in the composition of the grinder, the claw and hammer are consumable parts of the feeding grinder, and also affect the crushing quality and production efficiency of the main parts. talons and hammers should be replaced immediately after being damaged. to replace the claw, pull out the brake disc first. before pulling out, first open the round nut lock plate on the opposite side of the disc, tighten the round nut with a hook wrench, and then pull out the disc with a special puller. in order to better ensure the balance of rotor operation, care should be taken when replacing the gear claws. after replacement, static balance test should be done to make the mill work smoothly.
in the maintenance of time to pay more attention to the above three points, so as to ensure a better completion of the maintenance work.
