Spiral Classifier for Mining Beneficiation Mineral

The spiral classifier is divided into two types: high type and submerged type. High classifier is suitable for coarse particle classification, the maximum size of overflow is generally 0.4~0.15mm; submerged classifier is suitable for fine particle classification, the maximum size of overflow is generally below 0.2mm.
