The gravity spiral chute or gravity chute stands to adjust vertical line, and then the spiral chute can be fixed in the proper position by brandreth or wood. The mineral sand is sent to the two feeding ports by sand pump, and then the water is added to adjust the density of ore oar. A centrifugal force is produced at the flow rate of spiral slope due to the fact that ore oar flows from the high place. The mineral and sand are separated through the gravity and centrifugal force caused by spiral flow. The concentrate flows out from the pipeline to the spiral separator and the tailings are sent to the sand pool. Finally, the ore beneficiation is finished.
Spiral Chute is the best equipment for mining and mineral processing, which combines the characteristics of the spiral concentrator, shaking table and Centrifugal concentrator. It is made of the fiberglass lined with wear-resistant polyurethane and corundum cover, light moisture-proof, anti-rust. The spiral separator has the advantages of small occupation area, small water consumption, simple structure, no energy consumption, large capacity, easy installation, easy operation, small investment.

The Spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non-metallic minerals which have a big enough specific gravity difference. Spiral chute principleRaise the spiral chute and fix it in the proper position, sand pump send the ore to the feed inlet, adding water to adjust the concentration of the slurry. The slurry naturally swirls from high to low and generates an inertial centrifugal force in the rotating bevel flow rate. The mineral is separated from the sand by the gravity and centrifugal force of the swirl by the difference in specific gravity, grain size and shape of the ore. The concentrate flows into the concentrate bucket and is connected by the pipeline. The tail sand flows into the tailing sand bucket and is connected to the sand pool by the pipeline, and then drained by the sand pump to complete the whole process of the beneficiation.

Working principle of spiral separators The ore materials are separated by the specific difference of gravity force, inertial centrifugal force, flow force, and surface friction of the light and heavy ore particles in the downward flow along the spiral tube slope. Generally speaking, the movement of the slurry flow on the spiral concentrating tables surface produces two directions, one is the longitudinal flow which rotates swiftly around the vertical axis of the spiral chute and down along the chute surface, which is called the main flow, the other is the transverse flow which rotates around a balance layer of the ore flow itself, called transverse circulation flow or vice flow. Under the comprehensive action of longitudinal main flow and transverse circulation, the mineral particles on the surface of spiral classifier move differently along longitudinal and transverse direction due to different density, particle size and shape, and settle at the bottom of the spiral groove in different time and speed, so the mineral particles are stratified according to density and particle size.
Stratification is the first stage of the separation process, which is basically completed after the first processing circuit of the spiral separators. After delamination, the light mineral particles in the upper layer flow to the outer edge of the spiral separator machine gradually, while the heavy mineral particles in the lower layer are affected less by the longitudinal main flow and move to the inner edge gradually. In this way, the layered particles are divided again, which is the second stage called zoning, completed after series ( 3-5 times ) sorting process. After the above two stages, the ore intercepting trough and the ore receiving hopper discharge the different grade separation products from the clay trough, and the separation process is completed.
The grain size distribution rule along the cross-section of the wet spiral separator is as follows: under normal ore-feeding conditions, more than 70% of the ore particles are concentrated in the middle of the spiral concentrator beneficiation area; About 20% of the ore grains are located at the inner edge of the chute; Less than 10% of fine ore grains are near the outer margin.
