Submerged Spiral Classifier

【Introduction】:Classifier---the spiral of overflow end is completely immersed below liquid level

【Capacity】: 50～1410 t/d

【Improvement】: An automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated bringing more stable operation.

Spiral classifier working principle: Fine ore pulps are fed into water tank through feeding opening located in the center of settling zone. Beneath the inclined water tank is the ore pulp classification zone where ore pulps are stirred by low-speeded impellers. Fine ore particles are lifted up and then spilled out the overflow opening; coarse ore particles precipitate down to tank bottom and are discharged via discharge opening.

【Successful case】

Tanzania is located in southern Africa and is subordinate savanna climate. The air humidity is bigger, a lot of equipment are eliminated due to the rust. In a gold processing plant in Tanzania, the demand of ore separation is not particularly big, but the ore particle size is much more strict, Xinhai chose the submerged spiral classifier for customer according to the geographical location and customer needs, the hierarchic flooding size is equal or lesser than 0.015 mm, the classification results meets customer demand, recovery rate increase by 11%.
