[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.
