This is a Spiral Classifier (also called screw classifier or spiral separator), essential equipment for mineral ore beneficiation plants.
It is widely used together with ball mills to form a closed grinding and classification circuit, effectively separating fine and coarse ore particles. Fine ore flows out as overflow, while coarse ore is lifted and returned to the ball mill for re-grinding, ensuring consistent product fineness.
Features:
High classification efficiency, reliable performance, low energy consumption
Wear-resistant spiral blades, long service life, easy maintenance
Suitable for gold, copper, iron, and other metal/non-metal ore processing
Available in single and double spiral types to meet different production capacity needs
