[Product introduction]: A spiral of overflow end is completely immersed below the liquid surface.
[Processing capacity]: 50～1410 t/d
[Scope of application]: The spiral blades at the overflow end of the submerged spiral classifier are all immersed below the overflow surface, which is mainly suitable for ore classification with an overflow particle size of 0.15 to 0.07 mm.
[Product improvement]: Xinhai submerged spiral classifier has an automatic lifting device for returning sand to the sand returning end, which can cancel the configuration of the large spoon head of the ball mill and run more smoothly.
Advantages
The entire spiral of the overflow end of the submerged spiral classifier is submerged below the liquid level in the settlement zone, which has a larger area and depth;
Generally, electricity can be saved by 1-1.5 degrees per ton of ore;
Avoid frequent maintenance of the big spoon head;
Reduce the uneven impact on the big and small gears.
working principle
It is based on the principle that the solid particles are different in size and specific gravity, so that the sedimentation speed in the liquid is different. The fine ore particles float in the water and overflow, while the coarse ore particles sink to the bottom of the tank and are ejected by the screw to the upper part. A classification device for classification. Through the low-speed rotation of the screw, the slurry is stirred to make the fine particles suspend and overflow at the overflow weir. The coarse particles sink to the bottom of the tank and are conveyed by the screw to the discharge port as returned sand.
Generally, Xinhai submerged spiral classifier has 4-5 spiral blades at the end of the overflow weir, all of which are sunk in the slurry. This kind of classifier has a large settlement area, a deep classification pool, and the agitation of the spiral has little effect on the surface of the slurry. Therefore, the grading surface is stable, and the overflow is large and fine.
success case
Tanzania is located in southern Africa and has a savannah climate. The air humidity is relatively high. Many machines are often eliminated due to rust. For a gold mine project in Tanzania, the demand for ore sorting is not particularly large, but the ore particle size requirements are relatively strict. According to the customer’s geographic location and needs, Xinhai selected a submerged spiral classifier for the customer. The grading overflow particle size ≤ 0.015mm, the grading effect meets customer needs, and the recovery rate of beneficiation is increased by 11%.
