1. Simple structure and stable operation.
2. Separate bearings from water and materials, so as to avoid damages of the machine cause by contamination and rusting.
3. Suitable for various working environments.
4. With few material loss and high washing efficiency, it can fully meet the requirement of high-grade materials.
5. Longer service life, nearly without quick-wear parts.
6. Seldom maintenance to reduce the cost greatly.
It is widely used in the industries of construction sites, gravel plants (aggregate plants), and construction sites of hydropower station concrete dam, featured by high washing cleanness, reasonable structure, large handling capacity, small power consumption, and few sand loss (in washing process). In addition, GX series sand washer's drive part is completely separated from water and sand, so the fault rate is far lower than the commonly-used sand washing equipment, it is the optimal choice for updating and upgrading of the domestic sand washing industries.
Sand stone washing machine is arranged with an angle of 15 degrees, the lower part of a water trough is surrounded by weir plates on three sides to form a settling pond, the head part of a screw soaks into the settling pond, the screw is driven to continuously rotate by a motor through a speed reducer, and washing water is fed through orifice plates at the bottom of the settling pond. This machine has the functions of washing, dehydration and classification at the same time.
Washing: Sand stone is fed into the settling pond from a feed box, and driven to turn and grind with each other under the effect of rotating helical blades for removing impurities on the surfaces of the sand stone, and breaking down water vapor layer covering the sands, which is beneficial for dehydration. Washing water flowing from the orifice plates can form rising flow to exhaust impurities with small specific gravity outside a overflowing weir, thereby the washing is finished.
Dehydration: As particles with large specific gravity sink at the bottom of the trough, on the side of the bend plate at the trough bottom, sand stone is pushed upwards by the helical blades. Because the length of the water trough is higher than a lower horizontal line appropriately, residual water in the sand stone can be exhausted in the upward push process, and flows to the settling pond from a drainage ditch along the other side of the trough bottom, while the sand stone is discharged from a trough bottom discharge port at the upper end of the water trough.
Classification: The classification of materials is realized by discharging fine particles out of standard outside the overflowing weir, and the control method is to regulate the height of the overflowing weir and the rotational speed of the screw.
