Mineral separator and use method thereof

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. ...

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 motion. The reasonable design of the inclination angle enables the material to have a reasonable spiral motion, which is beneficial to Stripping of lightweight materials plays an important role

[0011] Fifth, the vibration of the bed surface is electromagnetic vibration or low-amplitude inertial force vibration, which is not conducive to the separation of materials with large particle sizes, and the material handling speed at the bottom of the bed layer on the bed surface is low, making it difficult to increase production capacity
