Spiral Chute

Spiral separator (spiral chute) is one of the gravity concentrators, which separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.




Spiral chute is widely applied to mineral separating of size 0.3 - 0.02 mm, such as ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphate, tungsten ore, tin, tantalum, niobium ore and other non-ferrous metals, precious metals and non-metallic minerals.


Working Principle

Spiral chute is working under the force of water flow, gravity, inertial centrifuge and friction. Slurry is pumped to the top of the spiral, and it enters a feed distributor that evenly distributes the feed to each spiral concentrator. The design and shape of the spiral make it work, when combined with gravitational acceleration. As the slurry travels the spiraling path down the spiral, mineral grains settle and start sorting according to size, density and to a lesser extend shape. Low density particles are carried with the bulk of the water towards the outside of the spiral, while particles with the greatest density migrate towards the inside of the spiral.
