The hammer crusher is packed with the whole machine. After unpacking, it can be moved to the proper position, placed stably, and connected with the power supply. Before use, check whether the transmission part of the machine is loose and other abnormal phenomena. The working direction of the machine should be the same as the direction indicated by the arrow. When Jingjiang Weineng mechanical crusher is used, the no-load test shall be carried out for 1-2 minutes, and the material can be fed only after no abnormal phenomenon is found. When feeding, the material flow shall be increased gradually, and the power consumption and operation status of the motor shall be investigated at any time. After the feeding and power supply are balanced and the operation is normal, the blanking gate shall be fixed and the operation shall be carried out. If the material is too wet and sticky in the middle of the way, which will affect the powder production, the material should be dried or the coarse sieve plate should be replaced. To replace the sieve plate, just open the front cover. When installing the front cover, pay attention to the joint tightness of the two hand wheels to ensure that the front cover and the casing are sealed. Stop feeding before stopping, and let the machine work for 5-20 minutes before stopping. In order to reduce the residual materials.
