Separation bed of a mineral separator

Abstract

The invention discloses a separating bed of a mineral separator. The separating bed of the mineral separator comprises a 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, the side of the right-angle edge opposite to the discharge edge is provided with a backboard for guiding materials to turn upwardly, the wider bottom edge of the bed surface is the feed edge, the narrower bottom edge is the discharge end, a plurality of air holes are opened in the bed surface, and the air hole size and the perforation rate can be different from the material baffle backboard to the discharge end so as to effectively separate mixture composed of materials with different densities and particle sizes. The separating bed of the mineral separator is capable of effectively overcoming 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 separation bed of a mineral separator, which is suitable for the separation of high-density and low-density mixtures, and is especially suitable for the separation of difficult-to-separate materials and high-temperature materials with high-density mineral content . 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...

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
