1. Check whether the vortex chamber is closed before driving to prevent the material from rushing out of the vortex chamber and causing danger. 2. Check the direction of rotation of the impeller, as seen from the direction of the inlet. The impeller should be turned counterclockwise, otherwise the motor wiring should be adjusted. 3. The starting sequence of the impact crusher and conveyor equipment is: Discharge → sand crusher → feed The crusher must be started at no load, and can be fed after the crusher is running normally. The order of shutdown is the reverse of the boot sequence. 1. The incoming granules are strictly in accordance with the specified requirements. It is forbidden to enter the sand making machine larger than the specified materials. Otherwise, the imbalance of the impeller and the excessive wear of the impeller will be caused. The base will block the impeller passage and the center feeding pipe, so that the crusher can not work normally. It has been found that large feeds should be excluded in time. 2. When the discharging device stops, the feeding should be stopped in time. Otherwise, the impeller will be crushed and the motor will be burnt. 3. The feeding force is continuous and uniform. 4. During the operation of the sand making machine, there must be no severe vibration or abnormal noise. Otherwise, it should be stopped for inspection. 5, the lubrication of the machine is dry oil lubrication, using Mobil vehicle grease special grade, the amount of addition is 1/2-2/3 of the bearing cavity, when the crusher works, add the right amount of grease. 6.
