Spiral Separator

A Spiral Separator, also known as a spiral concentrator or spiral chute, is a gravity separation device used to separate solid components in a slurry based on a combination of particle density, hydrodynamic properties (e.g., drag), and particle shape. The device consists of a tower around which a sluice is wound, with slots or channels at the base to extract denser solid particles that settle out of suspension. These separators are known for their simple structure, low power consumption, and high processing capacity. They are effective for particles typically ranging from 0.02 to 2 mm, with specific designs optimized for fine sand (0.074-0.5 mm) or slime (≤0.074 mm). Applications include the concentration of various minerals such as rutile, ilmenite, zircon, iron ore, gold, coal, tin, tungsten, tantalum, niobium, and monazite. Features often include durable polyurethane linings, modular feed boxes, and integrated launder systems, offering high separation efficiency with minimal maintenance.
