Features of screw sand washer

1.The screw sand washer has advantages of stable operation, high efficiency and durability, and low energy consumption.

2.The screw sand washer has the functions of cleaning, dewatering and classification.

3. The screw sand washer is high cleaning degree, less material loss.

Working principle of screw sand washer

The main part of screw sand washer is installed by 18 ° inclination, under the sink is a sedimentation tank composing of three weir plates. The screw head immerges in the sedimentation tank, and the screw is driven by the motor and continuously rotated, and the water is fed by the porous plates installed at the bottom of the sedimentation tank. The clean water entering by the porous plates forms the rising water, which brings the impurities with small specific gravity to the surface and overflow the weir plate to finish the cleaning. The larger particles sink into the tank body of the screw sand washer, and the screw blades push up the sand. As the upper part of the tank is above the water level, in the process of upward propulsion, the excess water of sand is removed, and the water that comes out flows into the sedimentation tank from the other side of the drain at the bottom of the tank. The classification of materials is achieved by fine particles overflowing over weir plates which do not meet the standards. The control method of the screw sand washer is to adjust the height of overflow weir plates and adjust spiral speed.

Case 1:Pakistan SL1200 Spiral sand washing machine

The customer uses SL1200 Spiral sand washing machine as the reagent removal equipment after the flotation of quartz sand. At present, the equipment has developed its own advantages and been successfully applied in the field.

Case 2:China Hubei SL1500 Spiral sand washing machine

The customer employs Spiral sand washing machine to clean silica sand and separate the clay and other impurities in the product in advance to obtain pure quartz sand products.

Spiral sand washing machine has its own unique advantages and it is especially suitable for silica sand cleaning. I have used the Spiral sand washing machine produced by Sinonine for two years. The structure design can make the cleaning more fully, especially for the production of high purity quartz sand, its adaptability is particularly strong. The equipment provided by Sinonine is excellent in both internal quality and external appearance. With such reliable main equipment playing its role, my whole quartz sand production line runs smoothly.


Sinonine sand washing plant can be applied to various sand production fields to clean, remove impurities, screen, grade, dewater. Sand products used in the different areas can be produced by different sand washing systems. Sinonine has developed a series of sand washing systems for construction, foundry, glass making, and oil fracturing, etc for processing different kind of sand, such as quartz, artificial sand, dune sand, river sand and other raw sand.
Sinonine high purity quartz sand production line is used to produce high purity and ultra-high purity quartz sand with SiO2 content higher than 99.999% for the production of quartz crucible and high-end electronics industry. Selecting the appropriate quartz stone as the raw material and processed in the high purity sand production line, through a series of purification processes the high purity quartz sand is obtained, an annual output of 3000-50,000 tons of large-scale industrial production capacity can be achieved. Sinonine owns the state-of-art technology in HPQ purification at the world's leading level.

The impact crusher is used for medium and fine crushing of stones. The design of Sinonine impact crusher adopts novel design principle, new concepts of crushing technology; meets demands of crushing different materials in different degrees. Sinonine Impact crusher not only has a great crushing ratio and fine products of uniform shape, also consumes less power per unit. The unique design of impact lowers its cost of repair and maintenance, thus improves its productivity and reduces its cost. Impact crusher proves the bright prospect of its application in mining processing industry through large scale projects.

Jaw crusher is primary crushing equipment in stone crushing line. Sinonine Jaw Crusher is of single toggle type with features of simple structure, easy maintenance, stable function, low operation cost, great crushing ratio. Jaw Crusher is used widely in mine, metallurgy, construction, road, railway, hydro-electric, and chemistry. It is suitable for the primary or secondary crush of large rock with compressive resistance no more than 320MPa. PE type is used for coarse crushing, and PEX type is used for fine crushing.
Apron feeder is to transport ore to primary crusher for evenly and continuously feeding. Apron feeder is important in ore feeding and conveying system, and also for short distance material delivery. Apron feeder is especially appropriated for transporting materials with large proportion, large particle size, and strong abrasiveness, and can work reliably in the open air, humidity and other harsh conditions. Apron feeder can be widely used in metallurgical, mining, cement, and building materials. Both horizontal and oblique installation is ok for apron feeder, the maximum installation angle of apron feeder can reach 25º.
VSI sand making machine is the latest successful crushing machine with the international advanced technology. Many years technology accumulation and modern processing equipment ensure the leading position of the VSI sand making machine in this industry. Excellent cost performance and reliability make VSI sand making machine outstanding in the similar products. VSI sand making machine is the perfect combination of the latest research result of Germany and Chinese present working conditions. It is currently the exclusive production sand making machine with the worlds advanced level. VSI sand making machine is suitable for crushing and shaping soft or middle-hard or extremely hard materials, widely applied to pebble, rocks (limestone, granite, basalt, dolerite, andesite), iron ore tailing, artificial sand making of stone chips. VSI Sand making machine is also applied to water conservancy and hydropower of engineering field, high-grade highways, expressway and railway, passenger railway, bridge, airport pavement, municipal engineering, sand manufacturing and aggregated rock shaping.
