Spiral Chute Equipment , Mining Gravity Separator Brief Introduction
The spiral chute is applicable for selecting materials with size 0.3--0.02mm, such as iron ore, ilmenite, chromite, pyrite, azorite, rutile, monazite, phosphorite, oxide ore, tin ore, tantalum ore, niobium ore and other nonferrous metals with distinct specific gravity difference, and rare matels and nonmetal minerals. The concentrating process is stable and easy to control with this spiral chut, allowing feeding thickness change to a large extent.
Spiral Chute Equipment , Mining Gravity Separator Working Principle
Spiral Chute is working under the 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. Â
