Screw Sand Washing Machine Clean Fine Material From Sand


Screw sand washing machine is widely used to treat materials in many industries such as mining, aggregate processing, metal mine tailings treatment and so on. So, can the screw sand washing machine remove the fine materials from sand?

The new generation of screw sand washing machine developed by LDHB is a multi-functional sand washing equipment with functions of water sand washing, fine sand material dehydration and recovery. The equipment is composed of spiral sand washing machine, dewatering screen and cyclone, which are combined together through ingenious design. Therefore, the fine sand is recovered from the sewage produced by cleaning, and the utilization rate of resources is improved.

Structure composition:

spiral sand washing device, overflow device, backwater device, tailings dry discharge device, separation and recovery device, water storage tank, water pump, motor, reducer, etc.


Working principle:

Firstly, the material is sent into the cleaning box of the spiral sand washer, and the material is pushed to the front outlet through the internal blades of the double spiral sand washer, washed with clean water in the middle, and then passed through the outlet. The double screw sand washer is a kind of spiral cleaning equipment, which uses the screw principle to push sand to separate from water and soil. The other end is provided with tailings dry discharge, the internal materials fall into the tailings dry discharge, the single direction exciting force generated by the vibration exciter on the tailings dry discharge screen makes the screen box move in a reciprocating straight line, the moisture on the materials falls into the water drop tank through the screen, the water drop tank is connected with the cleaning box of the spiral sand washer through the pipeline, and the feed port of the cyclone is connected with the water drop tank through the pipeline and the slurry pump Most of the coarse sand particles are discharged through the underflow port of the cyclone, while most of the fine particles are discharged through the overflow pipe, so as to achieve the purpose of separation and separation. The sand settling nozzle of the cyclone is located above the tailing dry discharge screen 10, forming the structure that the concentrated materials of the cyclone fall into the tailing dry discharge. The water separated by the cyclone flows into the recovery box, and the water flow inside the recovery box is stable Enter into the cleaning box of spiral sand washer to complete the cleaning, grading, fine sand recovery and dehydration of materials.

LDHB screw sand washing and recovery integrated machine uses vibrator to provide the source, with large exciting force, the output can reach more than 300 tons per hour, and can realize continuous operation. The combination of screening and cleaning makes it easy to produce and process, short production cycle, small floor area and large processing capacity.
