ClassifierWidely used in the concentrator and the ball dubbed in closed-loop sub-Cheng Cheng streaming mineral sands, or the gravity concentrator to grade ores and fine mud, or metal beneficiation process of the pulp to particle size grading, and washing operations The de -- mud, dehydration and other operations. The machine has simple structure, reliable, easy to operate and so on.
Spiral classifier is divided into: single-spiral classifier, double-spiral classifier. Spiral Classifier Spiral blade according to the overflow end of the immersion depth of the spillway different procedures can be made into the following two kinds:
1, high-weir-type classifier: the overflow is higher than the top end of helical blades spillway and overflow spillway below the end of helix center. Is mainly used for overflow particle size 0.83-0.15mm in ore grade;
2, sinking type classifier: the overflow end of the spiral blade all the submerged spillway below. Mainly applicable to overflow particle size of ore grading 0.15-0.07mm.
