spiral chute, manufacturer of spiral chute - xinhai

Ore pulps are uniformly fed into machine and form different layers as they pass across chute. Heavy minerals precipitate to bottom and are moved toward inner edge by the comprehensive action of various forces; light minerals are moved toward outer inner due to the speedy rotation. As a result, mineral particles with different density are divided into three zones------concentrate, middling and tailing.

Spiral chute is suitable for treatment of 0.6-0.03mm lode and placer, but high mud content is bad for separation. At present, spiral chute has been widely used in the treatment of iron ore, tungsten, tin ore, niobium tantalum ore, coastal and riverside placer and gold ore.

A plant in Shandong seashore, the ore are mainly - 0.15 mm grade except for a small amount of bigger particles, the plant area is small, but the capacity is large. According to plant site and processing capacity, Xinhai spiral gravity chute manufacturer specially added wear-resisting rubber in the internal of spiral chute to increase its wear resistance, acid-resisting and corrosion resistance. The layered minerals is obvious in the operation, the machine service life is more half a year than ordinary spiral chute.

The spiral separator is the best gravity concentrating equipment, especially for concentrating sand ore in seashore and riverside. It is made of the fiberglass, lined with wear-resistant polyurethane and covered with corundum cover. It has advantages such as lightweight, moisture proof, anti-rust and corrosion, noiseless, very suitable for the different feeding particle sizes and grades.

Capacity: 0.15-8t/h Feeding size: 0.3-0.02mm Advantages: 1. Simple structure, easy to operate and maintain 2. Low energy consumption 3. Relate wide range of particle size 4. Small volume, space saving 5. High productivity and efficiency

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.

gravity processing of hematite rock processing equipment - xinhai

Spiral chute of -hemaitite ore processing machine, the main components for the spiral chute, the cross-section shape is a cubic parabola. Compared with a spiral concentrator, the bottom surface of the spiral chute is more smooth and it is suitable for processing material of - 0.2 mm particle size. The hematite rock processing recovery limit can reach 20 to 30 mum. In a production process, slurry pump is often used to convey slurry to the sorting device which is at the top of the spiral chute, then the sorting device will convey slurry into the spiral chute. Under the action of gravity, slurry does spiral movement early downward the spiral chute, in the slurry water exists circular motion in two different directions, one is around the vertical direction to do rotary movement, also in the section of the chute of the hematite rock processing, the upper part of the water toward the outside of the movement, and the lower part of the water to the internal motion. After the slurry goes into the chute, its internal mineral particles need to complete the stratification, zoning and achieve the balance of the three processes to realize the processing, eventually makes the fine light mineral distribute in the outside part of the chute, heavy mineral distribute in the interior part. Next will introduce the three processes of hematite rock processing.

Stratification: after hematite layered into the chute of the minerals, under the action of gravity, usually heavy mineral is in the bottom of the chute, light mineral distribute on the slurry surface, and this process is generally completed in the first circle. Zoning, Light and heavy minerals in the cross section of the chute expanding and separating, and the centrifugal acceleration of the heavy minerals is small, in the process of sorting it goes toward the inner edge of the spiral chute, while light minerals has larger centrifugal acceleration, so it moves toward the outer edge of the spiral chute. This process is usually completed on the last lap. Reach balance, at this stage, mineral particles in the cross section of the chute no longer have basic motion, from outside to inside its final distribution are fine-grained heavy minerals, coarse heavy minerals, fine light minerals, coarse light minerals, slime.

Spiral chute has wide application in hematite processing, due to the surface of the chute is easy to wear, glass steel chute, wear-resistant rubber liner, and polyurethane rubber are commonly used to protect the table.
