Spiral sand washer - Jiaolong lifting - graded sand washer - sand washer manufacturer
The spiral sand washer can be divided into three types: low weir type, high weir type and submerged type (i.e. submerged type) according to whether the spiral blades of overflow Rui are immersed in the overflow surface and the depth of immersion in the overflow surface. The overflow weir top of the low weir spiral sand washer is lower than the spiral lower end bearing, which is only suitable for scouring and not suitable for grading. Therefore, in recent years, the low weir spiral sand washer has been screened.
The bearing at the lower end of the spiral at the overflow weir top of the high weir type spiral sand washer is lower than the upper edge of the spiral vane at the overflow end. High weir spiral sand washer is suitable for separating ultra-fine sand and dirt impurities with particle size less than 0.15 mm, and the product particle size is more than 0.15 mm. Therefore, it is more suitable for sand washing in hydraulic construction.
The spiral blade at the overflow end of submerged spiral sand washer is submerged below the grading surface (i.e. overflow surface), which is mainly used for fine particle grading. The classification surface of submerged spiral sand washer is large, and the spiral agitation has little influence on the classification, so the classification surface is relatively stable, and the overflow particle size is fine. It is generally applicable to ultra-fine sand with grading less than 0.15mm.
The spiral sand washing machines used for sand washing in construction projects almost all use submerged ones to recover useful extra fine sand. In addition, according to the number of screws of the spiral sand washing machine, it can be divided into single screw and double screw sand washing machines. Their operating principles are the same, but the number of spirals is different. The two spirals in the double spiral sand washing machine rotate in opposite directions, which is planned to collect the grit in the middle and discharge it.
The spiral sand washer can be divided into single drive and double drive according to the drive type. Generally, single drive is used for single screw sand washer, and double drive is used for double screw sand washer. In the double drive, the power of the two drive systems is the same, the rotating speed is the same, and the equipment commissioning method is symmetrical.
