Sand screws are limited in the amount of material smaller than the #50 (0.297 mm) that can be raked up the incline. As spiral speed increases, more turbulence in the weir reduces the settling rate of the fines and the ability of the sand screw to move those fines up the incline. To Adjust Sand Washing/Dewatering Equipment
If an application calls for a greater level of dewatering, they are often placed in series with a Dewatering Screen. Fine Material Screw Washers are especially simple for operations looking to wash dry screened fines. When compared to other sand washing systems, Screw Washers are a low-capital cost and low electric power user machine.

Fine material sand screws are machines designed for dewatering, washing, and classification. Adjustable overflow weirs enable operators to control the depth of the head and velocity of overflow wastewater. The large overflow feed box allows for either the retention or …
A dewatering screw press can be used in place of a belt press, centrifuge, or filter paper press. It is a simple, slow moving device that accomplishes dewatering by continuous gravitational drainage. Dewatering screw press are often used for materials that are difficult to press, for example those that tend to pack together.
Fine material washers, also frequently named dewatering screws are utilized to clean and dewater fine aggregates typically minus 10 mm or 5 mm (3/8'' or 4 mesh) to fine tune end products to meet specifications and to separate water soluble clay, silt, and micro sized fine particles.
CONTINUOUS DEWATERING SYSTEM FOR DREDGED SEDIMENT WITH HIGH WATER CONTENT Takashi Oida 1 ABSTRACT The Eco-Screw system provides a new method of mechanical dewatering that allows volume reduction and reuse of dredged sediment. A screw press, which is a core tool of Eco-Screw system, has not been used frequently in soil treatment.
Trio® Sand Washers utilize hydraulic separation with water as the medium to clean and classify sand particles by weight. Larger particles weigh more, sink and are collected in the bottom of the trough. The sand particles are transported to the inclined discharge end by a double pitched steel spiral shaft with replaceable cast wear shoes.
Dewatering Screw Classifiers once had a wide vogue and still are used in some pulp circuits. They were more or less troublesome because solids tended to accumulate on the sloping sides, sloughed off periodically, and plugged the discharge in the apex; the sand discharged was too dilute and contained too much slime; and sand was frequently carried over with the slime.
The Intensive Dewatering Screen is uniquely designed with an up slope of 5° and either 1200 or 1800 RPM's. This creates a substantial bed depth which both squeezes and packs the dewatered material. The percentage moisture content is generally ½ that of sand screws. Dewatering …
The mining and minerals industries require large aggregate washers, for which Falcon supplies components. Additionally, we manufacture components to move hay and other feeds for dairy farming equipment. Wastewater treatment plants use our conveyor screws to move sludge through the dewatering process.
The vibratory dewatering screen further removes moisture from the sand. Finally, in its most innovative feature, this GreyStone unit re-introduces the throughs from the screen back into the screw's washing process, where the screw again pushes the material to the unit's dewatering screen, increasing the amount of salable product.

Squeezing the Most Out of Your Decision for Municipal Solids Handling ... Dewatering Equipment Selection Screw Press Operates on the theory of solids conveyance through a cylindrical screen which ... amount of sand / grit which can cause abrasion.
Dewatering consistency is less accurate in an inclined dewatering screw conveyor when compared to a screw press. There are several screw press manufacturers on the market that can solve your sand dewatering issue. KWS designs and manufacturers inclined dewatering screw conveyors for …
The Condor line offers the same Classic Eagle Iron Works outboard bearings, capacities, mounting points, rising current classifier and adjustable weirs that are standard among all Eagle Iron Works screw washers. However, build with a Class 1 Dodge reducer, the Condor line offers a more standard gear box at a price you'll love.
Sand Screw. M 165S. The screen is a 5' x 16' and is teamed with a single screw. The screen is outfitted with strategically placed nozzles to scrub materials clean. High capacity dewatering screw delivers the fine aggregates while chutes and cross conveyors deliver the sized products. The portable chassis design is easy to transport to the ...
Dewatering Screen. Dewatering screen unit is a core equipment in tailings drying / sand dewatering process. The dewatering unit consists of hydrocyclones, linear motion vibrating screen, slurry pump and attachments. Compared to the high investment and operation cost of pressure filter, the dewatering unit enjoys many benefits.
Dec 01, 2014· While the Velco dewatering screen was very common in the 1980s for the U.S. coal industry, the aggregates industry only really started adopting dewatering screen technology in the early 1990s, and, even then, it was often used following fine material screw washers to improve the moisture content of the sand. Dewatering screens are simple ...
