Single And Double Screw Sand Washing Equipment 100-1000T/H Overflow

Single And Double Spiral Classifier Machine For Sand Washing

    Spiral Classifier Machine For Sand Washing is a kind of efficient sand and gravel washing machine, which is widely used for sand and stone washing, gradation and impurities removing. Spiral Classifier Machine For Sand Washing are specifically to produce quality sand for construction, highways, railways, building materials, water and electricity industries and more. Spiral Classifier Machine For Sand Washing can be divided into single spiral and double spiral washing machine, and with the features of power consumption, high cleanliness, good sealing structure, fully closed transmission device, adjustable weir plate ensure the durability of the product, good cleaning and dehydration effect, fine product stability and other characteristics.

     Spiral Classifier Machine For Sand Washing is based on the principle of different specific gravity of solid particles and the different sedimentation rate in liquid to realize washing process. The spiral sand washer is equipped with water spray pipes in cleaning tank. When working, a certain amount of water is supplied to flush and submerge the raw sand loaded into the tank from the inlet. At the same time, the spiral is continuously stirred and graded, and dirt impurities and tiny sand particles are suspended in the upper turbid water, gradually overflowing from the low-end overflow weir; the coarser sand particles sink to the bottom of the tank by gravity. As the spiral rotates continuously, the coarse sand is continuously agitated and graded in the water, so that the sand is fully washed.

Advantage of spiral classifier machine for sand washing:

1. Simple structure and the bearing is seperated from water and materials, thus avoiding damage due to rusting;

2. Quick and easy weir adjustment, applied to multiple working site;

3. Longer screw shafts for better dewatering, less outflow of materials washed, high washing efficiency, fully meeting the requirements of high-quality materials;

4. Long service life and less wear parts, long mainterance period, thus greatly reducing the cost;

       Spiral classifiers are widely used in ore dressing plants to be equipped with ball mills for closed-loop circulation to split ores, or for gravity. In the ore dressing plant, the ore and fine mud are classified, and the size classification of the pulp is carried out in the metal beneficiation process, and the operations such as desliming and dewatering in the washing operation are performed. The machine has the characteristics of simple structure, reliable operation and convenient operation.
