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.

The spiral chute mainly uses the inertial centrifugal force generated by the mineral of different density in the rotating motion of the spiral to separate the heavy and heavy minerals. At present, mineral resources are faced with such unfavorable conditions as depletion, refinement and hybridization, so improving the dressing efficiency of sorting equipment and improving the recovery rate have become the most important task in the development and research of mining industry. This article mainly from three aspects to teach you how to effectively improve the spiral chute dressing efficiency.

The diameter of spiral chute has direct influence on the capacity and recovery rate. Generally speaking, the larger the diameter of spiral chute, the larger the volume and velocity of ore flow, and the greater the processing capacity per unit time. According to the practical experience, the smaller the diameter of spiral chute, the smaller the lower limit of recovery particle size and the higher the recovery rate.

The intersection angle between the tangent line of the spiral groove section curve and the vertical axis is called the longitudinal inclination Angle. Therefore, a small dip Angle is used in the selection of fine minerals and a large dip Angle is used in the selection of coarse minerals. The suitable longitudinal inclination Angle can make the slurry run along the channel body, obtain good dressing index and improve dressing efficiency.

The transverse inclination is complementary to the longitudinal inclination. The transverse inclination Angle also affects the distribution of slurry flow on the trough surface. The greater the transverse inclination, the deeper the water flow. Therefore, a small transverse dip Angle is used for fine ore selection, while a large transverse dip Angle is used for coarse ore selection.

The number of turns in the spiral chute determines the separation distance and time. In the actual operation, it is necessary to determine according to the nature of the selected materials and the requirements of the operation indicators. When the useful minerals and gangue minerals are closely embedded and it is difficult to separate them, it is advisable to choose a large number of turns to extend the separation distance and time and improve the separation efficiency. But the number of turns should not be too much, otherwise it will increase the height of the spiral chute, increase the difficulty of the operation. Industrial choose not to use 4-6 more spiral groove.

The inner surface of the chute is required to be smooth, uniform and wear resistant to ensure that the slurry runs smoothly and does not clog. To enhance wear resistance, the inner surface of the spiral chute is usually coated with polyurethane wear-resistant rubber.

The shape of the mineral particles also affects the speed at which minerals move through the spiral chute. When the shape of useful heavy minerals is irregular or flaky and gangue minerals are round, the movement speed of heavy minerals is slow, which is conducive to stratification and settlement, reducing tailings grade and improving separation efficiency.

Because the spiral chute is mainly sorted according to the different density differences of minerals, the larger the density difference between the useful minerals and gangue minerals in the selected ores, the more favorable the separation will be.

To some extent, the volume of ore feed affects the thickness and velocity of ore flow. Therefore, in order to improve the efficiency, the coarse material feeding volume is large, the fine material feeding volume is small.

Spiral chute requirements for ore concentration greater than 30%, should not be too large or too small. If the concentration of ore is too large, the slurry viscosity increases, and the ore layer is not easy to be loosened, which will lead to the blockage of ore particle settlement, seriously affecting the stratification effect and the movement speed of ore particle, thus reducing the concentrate grade and recovery. If the concentration of ore is too small, the unit time processing capacity will be reduced, the material layer will become thinner and cannot be stratified and zoned, resulting in the increase of pulp flow rate, and the useful heavy minerals will be discharged before stratification and settlement, thus the tailing grade will increase and the separation efficiency will be reduced.

These are the three points that affect the efficiency of spiral chute separation: the structure parameters and properties of the spiral chute itself, the properties of the incoming ore and the process parameters of the spiral chute operation. In practical application, spiral chute operators must improve the above aspects of monitoring, if there are problems should be specific analysis, targeted adjustment, in order to obtain the ideal spiral chute sorting efficiency, to ensure the smooth production of the selection plant.
