Spiral Classifier

The spiral classifier is a classification device used in conjunction with wet mineral processing equipment. Based on the number of spirals, it is categorized into single-spiral and double-spiral models.

Sandreck’s equipment features a robust, wear-resistant structure and long-lasting spiral blades, offering high processing capacity and stable classification performance. Often paired with ball mills, it is widely used in mineral processing for various metal mines and in quartz sand purification lines.
