Spiral Classifier

Spiral classifier is a common classification equipment in beneficiation area, mainly has high weir type single spiral and double spiral, submerged single spiral and double spiral classifier. High weir spiral classifier is suitable for the coarse grain grading, the grading overflow particle size is generally greater than 0.15mm, Submerged spiral classifier is suitable for fine particle grading, the grading overflow particle size is less than 0.15mm in general. Spiral classifier is widely used in ball mill in the concentrator and deserves to shunt mineral sand into a closed cycle process, or use to graded sand and fine mud in the gravity concentrator, and metal beneficiation process for the pulp particle size classification, and washing of desliming, dehydration and other operations.
