Screw Washing Machine

 Working principle and application range
When the screw washing machine is in operation, the motor drives the impeller to rotate and the sand and gravel enters the washing chute through the feeding chute. Under the role of the impeller, the materials roll and grind against each other, which is not only conducive to remove the impurities on the surface of the sand and gravel, but also is helpful to destruct the water vapor layer that is coated on the sand and gravel in order to facilitate dehydration. At the same time, the addition of water to form a strong water flow can timely wash away the impurities that will be discharged out from the outlet of the washing chute. The clean sand and gravel will be taken away by the blade and then the gravel is poured into the discharging chute from the rotating impeller discharge chute, completing the cleaning operation. The screw washing machine is widely used in construction sites, gravel plants, concrete hydropower dam site and other industries.

Matters need attention in operation
1, the device should be installed on the level concrete foundation and fixed with anchor bolts.
2, the main host should be vertical with the horizontal in the installation.
3, the operators should check to make sure that all parts are fastened and the bin gate of the host machine is tight after the installation. If there were any problems, they should handle them in a timely manner.
4, the operators should make the configuration of the power line and the switch according to the power of the equipment.
5, after the inspection is completed, the commissioning with load or without load should be carried out. If the test is normal, the sand washing machine can be pt into production.
The screw washing machine, one kind of the sand washing machines, is featured with high cleanliness, reasonable structure, large capacity and low power consumption. What is more, the loss of sand in the washing operation is less. Especially the separation of the transmission parts and water and sand reduces its failure rate greatly when compared with the traditional sand washing machine. Therefore, the screw washing machine is the optimal choice when the sand washing industry is in the upgrade.
