The impact of sand making machine precautions:

  • 1. The normal operating temperature of the bearing box of the Sand making machine is 40°C~60°C, and the maximum allowable temperature is 70°C. After half an hour of operation, if the temperature exceeds 70°C, there is a certain problem in the bearing box and the machine should be shut down for maintenance in time.
  • 2. When the impact type sand making machine is operating under load, the material feeding granularity shall not exceed the maximum particle size allowed by the equipment.
  • 3. When the initial feeding of the impact type sand making machine is performed, there will usually be a non-equilibrium process of about 30~60s. In this case, the feeding cannot be stopped, and the feeding amount should be increased as much as possible until the vibration is reduced. When the feed material particles are large, intermittent vibrations are generated and return to normal after a few seconds. This is due to the normal conditions caused by the retention of material after the stones have accumulated in the material and are washed away. tension.
  • 4. The vibration of the impact sand making machine is intensified during operation, which indicates that there may be non-uniform wear between the wear parts and the rotor, which is caused by the non-uniform imbalance caused by the rotor and material accumulation, or the looseness of the pulley sleeve and other reasons. caused. After checking the normal vibration, stop the inspection. In addition, it is possible to set a vibration switch installed on the sand maker. When it detects an unbalanced vibration, it will stop actively before equipment damage and personal injury occur.
  • 5. The rotor wear parts of the impact sand making machine are designed to protect the rotor body against wear. In order to ensure trouble-free operation of the sand making machine, the inspection of the wear parts of the rotor and the inner material lining of the machine must be incorporated into the routine, and the wear parts of a work class cannot be satisfied and should be replaced in time. Every 8-10 hours of operation of the equipment, the interior and appearance of the rotor, sand maker, and grease should be inspected.
  • 6. Check the current of the sand making machine motor. If the motor current is too large and the motor is overloaded, the feeding amount should be reduced until the current value is normal.
