Basic Info

Model No.:  FG

Product Description

Model NO.: FG Capacity: 20-30t/h Speed of Screw: 20rpm Motor Power: 5.5KW Rotation Speed: 0.8-1.5 r/min Screw Diameter: 1000mm Trademark: TSDC Origin: Tangshan Type: Spiral Sand Washer Water Consumption: 20-60t/h Motor Type: AC Motor Certification: ISO, BV, CE, TUV, SGS Wheel Bucket Diameter: 2200mm Model: Fg-10 Specification: FG-10 HS Code: 84742090 This product is mainly used for sand factory, electric pole factory, work-site of building and concrete dam to wash, classifying and de-watering various sands.This sand washer adopt inclination of 15° , under the water tub, three weir plates form the sediment pool, the screw head is immersed in this pool, the screw is driven by electric motor through reducer rotating continuously, the fresh water is feeding from porous plate at bottom of sediment pool, this machine have three functions of washing, de-watering, classifying.

Washing: The sand is feeding into the sediment pool from the feeding box, acting by rotating screw blade, the sand is turning and rolling and grinding each other to eliminate impurity and water-air layer around sand to facilitate de-water. The fresh eater rising current from the porous plate carry foreign matter to water surface and overflow the weir plate, to finish washing processing.

De-watering: The sand with bigger density is sunken down to tub bottom, the screw blade push this sand upwards, when passing through upper tub of proper length above water level, the water is draining into sediment pool from another drainage ditch, the de-watered sand is out from the discharging opening.
Classifying: Material classifying is realized by overflowing the non-needed fines, the controlling method is adjusting height of overflowing weir and adjusting speed of screw.

1. Spiral Sand Washing Machine
Spiral classifiers are widely used for distributing ore in the close circuit with Ball Mill, grading ore and fine slit in the gravity mill, grading granularity in the flow of metal ore-dressing and desliming and dehydrating in the washing.

2. Spiral ore/sand Washing Machine Application:
Spiral ore washing machine applied to metallurgy, building materials, water and electricity industries washing, grading, impurity,etc. This series apply to the fine-grained and coarse-grained materials washing operation.

3. Spiral ore washing machine working principle:
Spiral ore washing machine is mainly composed of the transmission device, the helicoid, tub, lifting mechanism and lower bearings (bearings) and mineral composition valve.The material pours in 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 are carried off by the leaf blade,and finally poured into the discharge chute from the revolving impeller,completes the cleaning action.
