Spiral sand washing machine and spiral classifier, one kind of sand washing equipment, one kind of mineral processing equipment (also can be used for sand washing)

As the spiral sand washer and spiral classifier have great similarity in appearance, so many people will think they are the same equipment, in fact, the spiral sand washer and spiral classifier are different equipment, the spiral sand washer is a kind of sand washing equipment, the spiral classifier is a kind of mineral processing equipment. The biggest difference between the two is that the spiral sand washer blade is solid blade type, and the spiral classifier blade is air hollow blade.

Principle of spiral sand washing machine and spiral classifier:

Spiral sand washer must be tilted configuration, the lower part of the tank is surrounded by three-sided weir plate to form a sedimentation tank, the head of the spiral enters into the sedimentation tank, the spiral rotates continuously through the motor-driven speed reducer, and the washing water is supplied from the porous plate at the bottom of the sedimentation tank, which has the 3 functions of washing, dewatering, and grading.

Screw classifier due to the solid particles of different sizes and different specific gravity, so the settling speed in the liquid is different, fine ore particles in the water floating overflow, coarse ore particles settled to the bottom of the tank, pushed to the upper part of the screw discharged, is a device for mechanical classification, which is the mill mill ground powder filtration, with the screw will be rotated to the coarse material to the mill's supply port, will be filtered fine material from the overflow pipe discharged.

Capacity of spiral sand washer and spiral classifier:

In the sand washing operation, because of the large blade area of the spiral sand washer and the amount of sand conveyed at the same time, its handling capacity is about two to three times that of a classifier of the same size.

Screw sand washing machine and spiral classifier application:

Spiral sand washer is mainly used for sand and gravel cleaning, commonly used wheel sand washer, the output of spiral sand washer is related to its length and width.Spiral classifier is widely used in mineral processing plant, gravity concentrator to classify ore and metal beneficiation process and to classify the slurry for particle size, desliming and dewatering and other operations.
