1. Be sure to start the sand maker with no load. If there is any material in the crushing cavity, the motor will burn out due to excessive starting pressure. Therefore, before start-up, the sundries in the crushing room must be cleaned up to ensure no-load start-up, and then the machine-made sand raw materials should be added.
2. The performance of machine-made sand raw materials should meet the specified range. Different specifications of sand making machines have different requirements on the feed granularity, hardness and humidity of materials. When the hardness, caking and humidity of the material exceed the tolerance range of the equipment, blockage and wear will occur, and the sand making machine will be damaged in serious cases. Therefore, the selection of raw materials for machine-made sand must match the specifications of sand making machine equipment.
3. Repair and replace easily worn parts regularly, stop the machine regularly, open the observation door to observe the internal wear, and repair or replace new parts in time if the wear is serious, so as not to affect the normal operation of the sand making machine. It is important to note that it is forbidden to manufacture impellers without the approval of the manufacturer.
4. Do a good job of lubrication of sand making machine. Only when the sand making machine is well lubricated can it run normally and efficiently. When the lubrication is insufficient, the wear of the machine will increase and the bearing will become hot, thus damaging the machine. Therefore, the sand maker should check whether it is necessary to add lubricating oil after a period of use. After working for 400 hours, add the lubricating grease of sander properly, clean the bearing after working for 2000 hours, and replace it after working for 7200 hours.
5. Fasten the parts of sander in time. If the parts of the sander are loose, they should be fastened in time. These parts are fixed together by screws and other parts. If you move them frequently and violently, these screws will loosen. If there is abnormal sound during use, stop the machine in time for inspection. Find loose parts and tighten them in time.
6. Stop and rest regularly. The sand maker needs a rest after working for a long time. In order to pursue high-level production, if the equipment is operated day and night, it will definitely accelerate the damage. Therefore, according to the strength of crushed materials, it is very necessary to stop the equipment and adjust the rest parts after working for a period of time in the basic maintenance of sand making machine.
