The sand making machine is an essential equipment in the production of mining, building materials, and other fields. The sand making machine needs to withstand immense pressure and impact during production, which can result in wear, aging, and other issues with certain parts over time. The regular replacement of wear parts is essential to ensure the smooth operation of the equipment and prolong its service life. The sand making machine consists of seven main components: hopper, distributor, vortex crushing chamber, impeller, spindle assembly, base, transmission device and motor. Commonly used wearing parts include hammer head, impact plate, lining plate, “V” belt, screen, bearing seal and so on.
Maintenance and Repair of Sand Making Machine Wear Parts
1、“V” Belt Maintenance. The tension of the driving “V” belt should be properly adjusted to make sure the belt is evenly loaded. When the machine is driven by double motors, the “V” belt beside the machine should be group matched and make sure the length of each side is the same.
2、Wear Parts Maintenance and Repair. Scheduled stop the sand making machine to inspect the inner wearing condition, especially for feeding pipe, conical cap, impeller, upper and lower liner of the impeller, circular guard plate, wear part. If those parts are worn out, please replace or repair the worn ones and the wear part should be replaced at the same time with the same weight. In order to avoid any dangerous, it is prohibited to open the inspection door to inspect the inner condition during the machine operation.
3、Maintenance of the Bearing. The bearing of the main shaft should be cleaned every 2000 working hours. Usually, the main shaft bearing should be replaced after 7200 working hours with new one. The upper part of the main shaft assembly is movable, while the lower bearing is fixed. After installation, to push the belt by hand to test the sensitivity.
Hence, in order to prolong the wear part service life, especially attention should be paid to wear parts maintenance and repair during machine daily usage.
