Problems solved by technology

[0009] Third, the shape of the bed surface is a right-angled pentagon, and the ratio of the width of the feed side of the bed surface to the length of the bed surface is 4:10, resulting in short sorting time, low-density materials tend to contain high-density materials, and the separation accuracy is not easy improve
[0010] Fourth, the above-mentioned patent does not give the inclination angle of the backboard relative to the bed surface, and the angle of the backboard plays a guiding role in guiding the material to perform spiral

Embodiment 1

[0084] Embodiment one : see figure 1 , figure 2 , Fig. 3, which shows a separation bed 5 of a separation bed mineral separator according to the present invention. The material in the buffer bin is fed to the belt conveyor evenly by the vibrating feeder, and the belt conveyor feeds the material to the separation bed 5 of the mineral separator through the 304 feeding chute. The separation bed 5 is placed on an incline. The angle α between the longitudinal direction of the bed surface and the horizontal plane is -3°~+10°, the bed surface is divided into three sections, the angles of each section are not completely the same, and the angle β between the transverse direction of each section of the bed surface and the horizontal plane is -5°~15° ;, it is characterized in that the included angle of the feeding side of the bed surface changes with the change of mineral density, and the included angle of the 301 section is generally 3°~8°; the included angle of the 303 section bed s...

Embodiment 2

[0090] Embodiment two : When the particle size of the mineral is small, such as Figure 7 As shown in the bed surface, the bed surface is composed of a wear-resistant and temperature-resistant non-metallic rubber layer on the upper layer and a solidified metal layer on the lower layer. In the three areas of the bed surface 1a, 2b, and 3c, there are holes on the bed surface that penetrate the upper and lower layers with a certain perforation rate, which can be a uniform aperture, or the aperture can be divided into two specifications from the back plate to the discharge end. The large-diameter aperture is near the discharge end, and the small-diameter aperture is near the back plate. This makes the wind speed passing through the bed surface 7 more uniform, and the separation accuracy for small-sized materials is higher. The separator using the bed surface can overcome the defects of the prior art, has a reasonable pore size distribution, and has the ability to efficiently sep...

Embodiment 3

[0091] Embodiment Three : The main body of the separator is linked by the suspension system driven by the electric hoist. When the density of the separated minerals increases and fluctuates, it is necessary to adjust the angle β between the horizontal direction and the horizontal surface of the separation bed at any time. The combination can realize online automatic control. Improve the accuracy and efficiency of mineral separation.

Abstract

The invention discloses a mineral separator and a use method thereof. The mineral separator comprises an electric hoist hanger, a separating bed of the mineral separator, a gas-solid mixture gathering device, a cyclone separator, a bag-type dust collector, a main fan, a dust removing draft fan, a spray dust suppression system, an electric appliance controller, a monitoring system, an external heat source system and a mineral separator enclosing framework; the separating bed of the mineral separator and a vibrator are hung on the electric hoist hanger, the vibrator is connected with the separating bed of the mineral separator, and an air chamber at the bottom of the separating bed of the mineral separator is connected with an air supply device; the separating bed of the mineral separator comprises an approximately right trapezoid-shaped bed surface, the beveled edge of the right trapezoid is the discharge edge of the separating bed, a discharge baffle plate is arranged at the side of of the discharge edge, and the side of the right-angle edge opposite to the discharge edge is provided with a backboard for guiding materials to turn upwardly. The mineral separator and the use method thereof effective overcome the problem of narrow application range of an existing separating bed surface, is capable of selecting a reasonable bed surface inclination angle, enables the separation quantity to be improved, and enables the separating precision to be improved.

Description

technical field [0001] The invention relates to the field of mineral separation machinery, in particular to a mineral separator and its use method, which is suitable for the separation of high-density and low-density mixtures, especially for difficult-to-separate materials and high-temperature materials with high-density mineral content to separate. It is also suitable for the separation of coal, gangue and pyrite. Background technique [0002] At present, the mineral separators used in industrial production at home and abroad mainly include Chinese patent CN103008092, which discloses the separation of coarse ore and fine ore. The main separation medium is water, and it mainly separates materials with different particle sizes. [0003] "Coal Preparation Technology Volume One" published by Graham and Troman Co., Ltd. of the United States in 1988 discloses a countercurrent separator. It is a wind shaker with a rectangular bed surface and a 10° angle to the horizontal plane. ...
