Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings.

[0010] like figure 1 As shown, the pressurized feeding type three-product dense medium cyclone for high-density separation of the present invention is connected with the pressure feeding primary cyclone 1 and the pressure feeding secondary cyclone 2 through pipelines. The cone angle of the primary cyclone 1 is 5°-20°, the conical part of the secondary cyclone 2 is designed with a large cone angle, and the cone angle is 30°-180°, and one end of the primary cyclone 1 is provided with an inlet An interface 3 and a concentrate outlet 4; one end of the secondary cyclone 2 is provided with a tailings outlet 5, and the bottom of the secondary cyclone 2 is provided with a middle ore outlet 6. The installation inclination angle of the primary cyclone 1 is 30°-60°, and the primary cyclone 1 and the secondary cyclone 2 are installed horizontally.

[0011] The above is only a pr...

Abstract

The invention discloses a pressure feeding three-product dense medium cyclone for high-density sorting and belongs to the technical field of sorting equipment. The dense medium cyclone comprises a primary truncated cone-shaped cyclone and a secondary cylindric-conoid cyclone which communicate with each other through pipelines. The primary cyclone is a pressure feeding cyclone with its cone angle being 5-20 degrees, and the secondary cyclone is a pressure feeding cyclone with the cone angle of its cone part being 30-180 degrees. One end of the primary cyclone is provided with a medium inlet and a concentrate outlet. One end of the secondary cyclone is provided with a mine tailing outlet, and the lower portion of the secondary cyclone is provided with a middling outlet. The pressure feeding three-product dense medium cyclone provided by the invention can be used to effectively sort high-density minerals and is especially suitable for sorting of minerals with the density being greater than 2.4 kg / L. The dense medium cyclone has advantages of simple production technology, low cost, little environmental pollution and high grade of obtained concentrate products.

Description

technical field [0001] The invention relates to a sorting equipment for mines, in particular to a pressure-feeding type three-product dense medium cyclone for realizing high-density sorting. Background technique [0002] At present, the three-product dense medium cyclone has been widely used in the separation of the coal industry at home and abroad. The pros and cons of the dense medium coal preparation process largely determine the efficiency and economy of the dense medium coal preparation. The three-product dense medium cyclone uses centrifugal force to not only effectively separate the raw coal and produce qualified clean coal, but also concentrates the low-density suspension to further increase the density of the suspension to achieve secondary re-selection and final separation. Out of the two coal and gangue products. The density of the dense medium suspension used in the existing three-product dense medium cyclone is mostly below 1.8kg / L, so this kind of three-produc...
