Operation and maintenance of new-type spiral sand washing machines

  • 1When the spiral sand washer works, it will produce great vibration. It is recommended that the machine and the embedded weldments is installed on the concrete foundation, so that the equipment can be easily welded on the foundation. The depth and area of foundation should be calculated separately according to soil conditions, it is suggested that the base bearing weight roughly is three times that of the sand washing machines; the machine installation dimensions can refer to the foundation drawing.
  • 2After the equipment installation is in place, check whether the reducer and gearbox are shifted, whether the water tank is consistent with the big spiral gap, after adjusting well, fixing and welding the equipment on the foundation.
  • 3The lubricating oil should be added to adjust the height of oil surface. Generally, it is advisable to make the height at the line under 50% of shaft center.
  • 4After the installation and adjustment of the spiral sand washing machines, the test operation shall be carried out, and the no-load test shall be achieved:
    • Continuous operation for 2 hours
    • All parts should be firm and free of looseness.
    • The reducer and gearbox without the abnormal sound
  • 5The load test shall meet the following requirements in addition to meeting the requirement of no-load test.
    • When feeding the materials, don't make the material strongly impact the water tank, don't have the partial feeding or the stack feeding phenomenon in the water tank, to avoid damaging the machine.
    • The feeding material size should meet the design requirements of spiral sand maker.
