Product Overview




The spiral sand washing machine is one of the main equipments of Henan Xingyang Mining Machinery Manufactory.
Over the past decades, with the continuous practice of domestic and foreign markets, the gradual upgrading of ancillary products, the current sand washing equipment has become a mature assembly line equipment of our factory.




Can handle material: It is suitable for washing, grading and cleaning of fine-grained and coarse-grained materials, and is mainly used in desliming and operation of large quantities of sand and stone used in construction sites, sand and stone factories, prefabrication plants, ore dressing plants and hydropower sites. (especially suitable for river sand, mountain sand, stone powder in stone yard and road-building mechanism sand).







The sand washing machine is composed of gears, reducers, brackets, sedimentation tanks, impellers, pulleys, motors and other important parts.

  • The transmission device:It is composed of the electric motor, big and small belt pulleys, triangle belt and gear reducer.
  • Gear reducer: speed ratio i=68.61, a whole sealing oil bath type. The gear is steel cylinder helical gears. The materials of the gear reducer are HT20-40 with industrial pad liner(δ=0.5mm). The liner is smeared withfluid sealant. The reasonable design of the gear and the gear reducer ensures the accuracy of transmission.
  • Screw arbor: Screw diameter D=920mm, Thread pitchS=445mm, HeadZ =1, Cylinder number N=15.5. The materials of screw blade is Q235A, δ=8mm armor plate jointed continuously to the hollow shaft. The screw of each thread pitch iscomposed of six liners. Liner materials are high manganese cast steel (ZGMn13). The screw liner is connected by bolt, nut and screw blade. Hollow shaft is seamless pipe (219X22) which ensures intensity and rigidity. On the both side, jointing ring flange which is connected to lug and under-part bearing respectively. This structure meets the demand of sand to wash, separate, and classify and dehydrate fully.


  • Trough: It contains shell, input devices, right weir plates and left weir plates.Trough is steel plate jointed into water tight structure. Right and left weir plates and input devices are connected by bolt, nut, and grower washers. Right weir plate and left weir plate&=3(mm)rubber sheet for sealing.
    On the bottom of trough, it installs sheet bending machine on one side which keeps a suitable clearance with the out edge of the impeller in order to move particles forward. Another side is gutter used for discharging moisture from sand.
  • Overflow platecan be adjusted: upgrade one or two weir plates, can curtail the valid length change the admission velocity of washing water, can increase working head and change overflow speed, getting rid of granule according to the demand of classification.
    Wire plates can provide compensation when trough’s location tilts by the mistakes of assembling and installment.




Working principle: This sand washer should be installed with an angle of 15 degree,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, dewatering, classifying. 

  • Washing: The sand is feeding into the sediment pool from the feeding box, with the help of rotating screw blade, the sand is turning, rolling and grinding each other to eliminate impurity and water-air layer around sand to facilitate de-water. The fresh water rising current from the porous plate carries 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 sedimentpool from another drainage ditch, the de-watered sand is out from the discharging opening.
  • Classifying: Material classifying is realized by overflowing the fine particle that does not meet the standard requirements. The controlling method is adjusting height of overflowing weir and adjusting speed of screw.
