Regular Check and Maintenance of the Rock Crusher

Over the past several years, many companies established inspection maintenance system for weeks, months and years of production, making the check as well as maintenance work of rock crusher normalized, institutionalized and efficient.

Regular check and maintenance carries out for weeks and months. Companies arrange skilled and experienced professionals to proceed with check and maintenance for rock crusher every week and every month. Check highlights include:

1. When checking the minor terms of the stone crusher, it is necessary to carry out pressure relief of the hydraulic pressure station. We need to open the decompression valve which needs manual operation of the hydraulic pressure station to make sure the depletion of the pressure of the locking cylinder as well as the pressure of the release cylinder. And then turn off the power supply of the main motor and hydraulic pressure station, avoiding hurting people caused by high pressure. And in the middle of changing liner plate, it is necessary to check the matching surface of liner plate together with fixed cone as well as movable vertebrae, and to rub out any nick as well as skin needling on the fixed cone as well as movable vertebrae. And then clear up the antirust coating on the new liner plate, making sure the close matching with zero clearance between liner plate and cone. In addition, it is required to proceed with regular check of the screw thread wear pattern of fixed cone, adjusting ring as well as locking ring.

2. Check the wear condition of balance weight and balance weight guard board. If find out severe wear and tear of the balance weight guard board, it is necessary to replace immediately. When changing copper bush under the cone as well as the bushing of eccentric locking collar, it is required to make sure if the inner diameter of the movable vertebrae as well as the inner diameter of the eccentric locking collar is up to the standard requirements, and then install new bushing. When install the new copper bush, it is necessary to use dry ice or liquid nitrogen to cooling the new copper bush, and the cooling time is necessary to be more than 2 hours. And then install them into cone as well as eccentric locking collar at random. And it is unable to use hammering or pressing methods to carry out installation. And before installing assembly of movable cone as well as assembly of the eccentric locking collar, we need to clear up the outside wall of the eccentric locking collar to wipe off cats and dogs as well as striation. Otherwise, after changing copper bush under the cone as well as the bushing of eccentric locking collar, in the middle of running rock crusher, it is necessary to carry out breaking in according to operation instruction.

3. Check wear and tear condition of large tendon guard board of lower bearing bracket, transmission shaft guard board as well as the liner plate of the main frame. If find out wear and tear, it is necessary to change immediately. And at the same time, check all the hydraulic hoses to figure out if there is any leakage or wear or tear, if there has, change immediately. As for changing the large gear and small gear, it is required to mix up bottom clearance and backlash.

4. To clear up the filter cleaner of horizontal shaft air blower, avoiding the blocking of filter, preventing the dust from entering the rock crusher to pollute the lubricating oil. And then check if the indicator light on the hydraulic pressure station button box is normal. And if the temperature sensor, pressure sensor as well as charge level indicator sensor are normal. If there is wear and tear we need to change promptly. And formulate the regular check system of rock crusher is a good way to broaden sources of income and reduce expenditure.
