LZZG sand washing machine is a type of water use of sand making machine type and makes the necessary equipment of sand, sand washing machine can mix mechanism of sand from the sand wash powder and impurities to improve the quality of the sand. It can also be clean separation of sandstone from dirt and debris, its novel sealing structure, adjustable overflow weir plate, reliable transmission to ensure the cleaning dehydration effect.



How to process silica sand equipment?

When the machine works, the motor drives the impeller slowly after the velocity, reducer and gear has been decelerated. The sand enters the wash trough through feeding tank, rolls pushed by the impeller, and rubs mutually to remove the impurities covering on the surface of the sand, at the same time, it breaks the water vapour which favors dewatering; At the same time, the strong water flow takes the impurities away, and discharged from the overfall. 

The clean sand is removed by the impellers when the water falls from the nets into the wash trough, which can dewater the sand and save water. The sand is then poured into the discharge chute and cleaned finished.

Why choose LZZG silica sand processing equipment ?

 

1.Simple structure.
2. The bearing device of impeller drive is separated from water and materials with water, to avoid the damage of the bearing.
3.New sealing structure and reliable transmission device.
4.Reasonable structure.
5.High capacity, low power consumption.
6.Easy structure, stable operation.

Our sand washer/sand washing machine includes two types for choice: bucket wheel type sand washing machine (XS series) and screw/spiral sand washing machine

Sand washer/sand washing machine(sand washing and sieving machine) is the commonly used equipment in artificial sand making production line. It is widely used to process silica sand, river sand, yellow sand, sea sand, etc. It is used to remove the dirt and impurities in sand for sand washing, classifying and grading to meet the standard.

How to distinguish wheel sand washer with screw sand washer?


wheel sand washer

In the sand making process, the Bucket Wheel Sand Washer is used to clean the soil and dust in the sand, to achieve the purpose of cleaning the sand, and can also be used in the extraction of sand in ore dressing and other similar processes. This machine is suitable for highway, hydro-power, construction and other industries.

The electric motor runs slowly with the impellor after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolls with the impellor, and grinds each other. The impurity covering the sand is washing away. At the same time, add more water, the strong water flow will take away waste and some low-weight wastes from washing launder. Through the above process, the washing function is finished. The clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back in the washing launder. On one hand, water is removed from the sand and stone; on the other hand, the water can be fully used. Finally, the sand and stone goes to the out launder from the rotary impellor to finish the washing task.

Screw sand washer

Screw washer which is widely used in washing off silt and stains from manganese ore, iron ore and other low-grade mineral. Also it suitable for scrubbing material which contains tough insoluble clays, conglomerates or soft stone.

This machine drive the spiral stirring shaft depends on speed reducer and rotate in different directions, and the minerals which enter the tank were washed by water and stir strongly by blade. The sewage was overflowed at the end of tank, the cleaned minerals were lifted up along the blade and discharged at the beginning of tank.

Fine Material Screw Washers wash, classify and dewater -10mm or 3/8″ solids material in one machine. They typically settle for feed suspension from Wash Screens, Sand Classifying Tanks, Hydrocyclones, Hydrosizers™ and different Fine Material Screw Washers. If associate degree application needs a larger level of dewatering, they'retypically placed serial with a Dewatering Screen.

Fine Material Screw Washers ar particularly easy for operations wanting to clean dry screened fines. in comparisonto different sand laundry systems, Screw Washers ar a low-capital price and low power user machine. they're wideemployed by construction sand producers, mining firms, star salt/brine processors and glass utilisation plants.

How does a sand screw washer work?

To accomplish the ideal outcomes with a Fine Material Screw Washer, sand or other fine material is coordinated to the feed confine the confound plate. Coarse, heavier materials settle to the base of the case, while ultra-fine waste portions are conveyed by the up-ebb and flow of water to the surface and flood the weirs. 

Heavier material that settles to the base is passed on up a 18-degree incline toward the release end. The rolling and tumbling of the material discharges fines and some lightweight divisions into suspension. It additionally gently scours shallow dirts from the sand/mineral surfaces. As the material is passed on toward the release end, the water starts to isolate from the material. A divert in the washer box/tub is given inverse the passing on side to enable water to deplete from the solids and flood the weirs. 

 

So as to legitimately hold material in a screw washer, a quiet survey territory must be kept up. The feed box inside the bewilder plate is utilized to coordinate material far from the quiet pool region; in any case, if the pool territory is fierce, better material that might be attractive in the last item will flood the weirds. The perplex plate isolates the washer box feed territory and keep the pool region quiet. In a few applications, makers may expel the confound plate and feed the material near the back plate of the weir to help shake the trick territory and flood unwanted material. 

The speed of the Fine Material Screw Washer is dictated by the percent passing 50 work in the ideal item. In the event that the screw washer is running excessively quick, material does not get an opportunity to remain on the flight sufficiently long to dewater. The material will tumble off of the flight and come back to the survey territory, driving the container to in the end load up with sand and slow down the screw shaft.
