Working Principle of Screw Sand Washing Machine  

  The material pours in the from the end of input,the spiral impeller rotates by the driven of the motor and the reducer,and then push the material inside the hopper close to the end of output.Thus,under the action of being advanced,mixed and the flushing water,the mud wrapped on the material and the impurity go separately.Finally,the separated fine sands are discharged from the discharging port under the advancing movement of the spiral.Thus,the continuous work of washing sand is finished again and again.Promptly carries off the impurity and the small proportion foreign matters,and discharge from the overflow port tank washer,completes the cleaning action.The clean sand and crushed stone is carried off by the leaf blade,and ids finally poured into the discharge chute from the revolving impeller,completes the cleaning action.
