Spiral chute, also known as a spiral separator, is commonly used in iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten ore, chrome, tin ore, niobium ore, and other non-ferrous metals, rare metals and non-ferrous metals, and metal ore separation. In particular, the effect of placer mining on seashores, riversides, sandy beaches, and creek channels is more significant. The spiral chute mainly uses the gravity, inertial centrifugal force, water flow force and groove surface friction force experienced by light and heavy mineral particles in the downward flow along the spiral slope to sort.

working principle

It mainly comprises six parts: ore distributor, ore feeding trough, spiral trough, ore cutting trough, ore receiving bucket, and trough bracket. Stand the spiral chute up, calibrate the vertical line, and fix it in place with an iron frame or wood. The ore is sent to the two feeding ports on the top of the spiral by a sand pump, and supplementary water is added to adjust the concentration of the ore paddle. The ore paddle naturally swirls from high to downwards, generating an inertial centrifugal force in the rotating slope flow rate. Based on the difference in specific gravity, particle size and shape of the ore, the ore and sand are separated by the gravity and centrifugal force of the swirling flow. The concentrate flows into the concentrate hopper and is connected through a pipeline; the tailings flow into the tailings hopper and are connected to the sand tank through a pipeline. Then, a sand pump is drained away, completing the entire mineral processing process.
