The working principle of the impact sand making machine is simply the principle of stone rock. Let the stone collide with the stones that have been accelerated by the impeller during the natural falling process to achieve the purpose of breaking! The stones that are accelerated and collide with the naturally falling stones form a vortex, and the crushing process is repeated twice in the return process, so the wear of the machine counterattack during operation is very small. However, we still need to maintain the equipment on a regular basis, and we need to pay more attention to the following aspects during maintenance.
1. The bearing at the upper end of the main shaft of the main shaft is the swimming end, and the lower end is the fixed end. After assembly, the pulley should be turned to be flexible for normal eating. The spindle bearing is filled with an appropriate amount of grease every 100 hours of operation, and the main bearing of the main shaft is cleaned once every 2000 hours. Depending on the use and maintenance, it is generally used for 5,000 hours to replace the new bearing.
2. In the operation of the impact type sand making machine, due to the high running speed of the equipment, special attention should be paid to the production of the whole body, and the relevant personnel should be away from the equipment. If you need to repair the machine, it should be done after the machine is stopped.
3. In addition to the uninterrupted working condition, we need to stop the observation door regularly and observe the internal wear of the crusher, such as: center feeding pipe, cone cap, impeller upper and lower runner liner, vortex chamber liner, wear-resistant If the wear level is serious, the manufacturer should apply for replacement or repair in time. When replacing the wear block, replace it at the same time to ensure the same weight of the wear block. It is found that the impeller body wear should also be replaced or repaired in time.
