The screw type sand washing machine(also called spiral sand washing machine) is suitable for use in various locations, including construction sites, sand factories, hydroelectric power stations, concrete dam sites, and telegraph pole factories. It is used for processing sand as required by customers, primarily including "70" sand(also known as No. 70 sand, is a common casting material. It is a type of quartz sand with a moderate grain size, uniform particle distribution, moderate hardness, and high-temperature resistance. This type of sand is frequently used in the casting of various metal products, such as iron, steel, and copper. The particle size of "70 sand" typically ranges from 0.5 to 1.0mm, which is a medium-coarse sand. Its particle size is conducive to easy flow and filling of mold cavities, while also ensuring a smooth surface on the metal products after casting), glass quartz sand, and grout pressure sand. This machine can carry out washing, grading, and dewatering operations.
The design of the screw type sand washing machine incorporates a 15° tilted arrangement, with the lower part of the water tank consisting of three side weir plates, creating a sedimentation tank. The spiral head does not enter the sedimentation tank but is continuously rotated by a motor through a reducer. Clean water enters the tank from the bottom through a porous plate. This equipment serves three main functions: cleaning, dewatering, and classification.


  • The overall structural design is rational, ensuring stable operation, high washing efficiency, large processing capacity, and a high degree of cleanliness.

  • Specially designed feed plates and adjustable long overflow weir plates, in conjunction with optimized screw speeds, ensure precise material washing and grading.

  • Optimally designed drainage channels are in place to maximize the removal of moisture from the materials.

  • The new sealing structure minimizes the maintenance works and costs of the equipment.

  • The screw blades are manufactured from wear-resistant materials, ensuring the continuous operation of the equipment and lower operational costs.


During the operation of the screw type sand washing machine(spiral sand washer), materials are evenly fed into the feed box. A certain amount of water is continuously introduced into the main trough. The transmission system drives the spiral shaft to rotate at a specific speed, causing the materials to flip, roll, and move toward the discharge outlet within the trough. Fine-grained materials and impurities are discharged through the overflow weir with the overflow water, while coarse-grained materials exit through the discharge outlet. This process facilitates the washing, grading, impurity removal, and dewatering of materials.
