What are the 10 operation requirements for a sand-making machine?

10 Operation Specifications Of Sand Making Machine

1. Check whether the vortex cavity observation door is closed before starting the machine to prevent sand and rushing out from the vortex cavity observation door and causing danger.

2. Check the rotation direction of impeller. From the direction of the feeding port, the impeller should rotate anticlockwise; otherwise, the wiring of the motor should be adjusted.

3. The starting sequence of sand making machine and conveyor is: discharging- sand making machine- feeding.

4. Sand making machine must be started without load and can be fed after normal operation. The stopping sequence is opposite to the starting sequence.

5. The size of raw materials must meet requirements. Raw materials that are larger than requirements shall not be allowed to enter sand making machine. Otherwise, it will cause the imbalance and excessive wear of impeller, or even cause the blockage of the impeller passage and the central feeding tube, so that the sand making machine cannot work normally. So, once find out that the raw materials are too large, the operator should eliminate them in time.

6. Stop feeding raw materials in time after the vibrating feeder is stopped. Otherwise, the impeller will be crushed and the motor will be burnt out.

7. The raw materials should be fed evenly and continuously.

8. During the operation of sand making machine, there should be no violent vibration or abnormal noise, otherwise, stop the machine and check.

9. Lubrication of sand making machine: Adopt the required special grade of automotive grease, add 1/2-2/3 of the bearing cavity, and add appropriate amount of grease every shift of the sand making machine.

10. forced of the driving V-belt should be adjusted properly to ensure that the V-belt bear even force. When driven by dual motors, the V-belt on both sides should be grouped and matched so that the length of each group is as consistent as possible. The current difference between the two motors shall not exceed 15A.
