Main parts: ore distributor, feed chute, spiral chute section, cutting trough, collecting hopper, support, etc. Spiral separator types: single spiral separator, lab spiral separator, rotary spiral separator, multi-deck spiral separator.
Application: The spiral separators are designed for classifying the granularity 0.3-0.02 millimeters fine grain like iron, hematite, ilmenite, chromite, brasses, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other Non-ferrous metal, rare metal, and non-metallic minerals with different specific gravity in the mineral processing plant.
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.

Spiral concentrators are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particles hydrodynamic properties (e.g. drag). The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid particles that have come out of suspension.
As larger and heavier particles sink to the bottom of the sluice faster and experience more drag from the bottom, they travel slower, and so move towards the center of the spiral. Conversely, light particles stay towards the outside of the spiral, with the water, and quickly reach the bottom. At the bottom, a cut is made with a set of adjustable bars, channels, or slots, separating the low and high density parts. Many things can be done to improve the separation efficiency, including: -changing the rate of material feed -changing the grain size of the material -changing the slurry mass percentage -adjusting the cutter bar positions -running the output of one spiral separator (often, a third, intermediate, cut) through a second. -adding wash water inlets along the length of the spiral, to aid in separating light minerals -adding multiple outlets along the length, to improve the ability of the spiral to remove heavy contaminants -adding ridges on the sluice at an angle to the direction of flow.
Typical spiral concentrators will use a slurry from about 20%-40% solids by weight, with a particle size somewhere between 1.5-.075 mm (17-340 mesh), though somewhat larger particle sizes are sometimes used. For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm3; and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape. A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in the same space as one, to improve capacity.

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.
