XS Sand Washing & Dewatering Machine

No matter which kind of sand washer used in sand processing plant, the final sand always contains a large amount of water. But dry sand is needed by most of customers. In order to solve this problem, our company researched and developed XS sand washing & dewatering machine successfully, which combined washing with dewatering functions. It perfectly solved the above problem. Working principle The work style of this series sand washer is rotary and movable. The bucket is driven by motor through reducer and rotates in circle. There are many sand storage web grooves in grille form. When the bucket moves, sand can be put out by storage web groove after being cleaned, waste water outflows through web groove’s holes. Meanwhile the washed sand will be fed into PU screen directly for dewatering. In the process of sand washer is running, sand is discharged through the feeding groove. Sand washer can circumrotate and discharge sand periodically by motor’s continuously running, which can realize the batch production. It works the same as XSD sand washing machine. After vibrating and dehydrating on the PU screen, dry sand is the final product. Features 1. Sand washing and dewatering machine integrated sand washing machine, dewatering screen two kinds of equipment advantages and characteristics. 2. Greatly reduce the sand in the mud, water, dust, impurities and so on, improve the sand and the price. 3. Energy saving and environmental protection, low energy consumption. 4. The whole machine installation, convenient and fast transportation. 5. Low failure rate and long service life.

DS Series Multi-function Sand Washer

Modular wash plant as a piece of representative equipment that combines multiple washing, coarse and fine materials concentrated dewatering, fine sand recycling, and other functions in one equipment. It is applicable to sand and gravel plants, construction sites, hydropower dams, glass manufacturing, oil well development, and other industries. Compared with the washing and recycling machine, it has been greatly improved in performance. Working principle The qualified materials after classified by screening equipment flow into the screw sand washer through a chute or pipeline. Sand and gravel are fully separated from impurities and mud through the fully cleaned, soaked, and broken by screw mixer. Fine sand and muddy water are deposited in the tail of the sand screw, and the fine sand is recovered through a cyclone separator. Then the coarse and fine sand enters the wheel sand washer machine at the same time for secondary cleaning to achieve complete separation of sediment. The coarse sand is lifted onto the high-frequency dewatering sieve by the impeller of wheel sand washer, the overflow muddy water flows into the dewatering screen water tank and concentrated by cyclone separator, and is dehydrated by the vibration of the screen to finally realize the cleaning, recovery, dehydration and dry heap discharge of gravel. Features 1. Energy energy saving and environmental protection are the major themes of multi-functional sand washers. Functions include sand washing, fine sand recovery, dehydration and de-sludge, concentration, and classification, which can effectively remove sand impurities and obtain high-quality sandstone products with clean and low water content. 2. Multiple functions, reasonable structure, easy operation.

Trommel Type Sand Washer

Trommel type sand washer is designed to classifying, washing and removing impurities from sand, gravel, mineral, frac sand, coal, metal mine tailings, ceramic, piling mud, river dredging and construction waste, thereby improving the products quality. Trommel type sand washers are mainly divided into two parts, one part is the drum screen for grading, the other part is the sand washer machine, separator, dewatering screen for sand cleaning, dehydrating and recovering. Working principle Material feed into the front-end drum screen firstly, turn over and roll on the screen surface and form two materials with different grain sizes due to the tilting and rotation of the drum device. Unqualified materials are discharged through the discharge opening at the tail. The qualified materials enter cleaning tank, roll and grind each other under the rotation of bucket to remove impurities covering the surface of gravel. At the same time, a strong water flow formed by trommel sand washer take away the impurity and small specific gravity, and discharged from the overflow port; the clean sand is taken away by the wheel impeller onto dewatering screen for dehydration treatment. The overflowing muddy water in water storage tank (including a small amount of qualified materials, waste water, impurities) is pumped into the hydrocyclone separator by high-pressure slurry pump. After the centrifugal concentration, the qualified material is sent to dewatering sieve for dehydration treatment. Waste water and impurities are discharged into the return tank through the separation device. Features 1. Reasonable structure. The drum screen and wheel sand washer are combined with the vibrating screen to form an integral structure. The multi-stage screening and cleaning can better perform screening and cleaning, and promote the development of the screen washing industry. 2. Large processing capacity, high efficiency, easy to produce and process, short production cycle, small floor space. 3. The dual slurry pump and double cyclone are connected together to form two groups of structures, which are circulating water flow and save water consumption. 4. High degree of integration, can realize mobile operation.
