Example Embodiment

[0027] The invention provides a dry cleaning screening method of bauxite and a related production equipment system. The dry cleaning screening method includes the following steps: drying the bauxite into dry ore, breaking and separating the dry ore into ore and mud powder, and separating the ore and mud powder through screening to remove the mud powder to obtain the pure bauxite ore. The present invention will be described in further detail below through the equipment used in production and the drawings.

[0028] Such as figure 1 Shown is a schematic structural diagram of a bauxite dry cleaning screening system of the present invention, which is an embodiment of the present invention. It is composed of the following devices: the ore hopper is connected to the bauxite inlet of the drying drum through a conveyor belt; the outlet of the drying drum is connected to the inlet of the sludge separator, and the coarse ore from the sludge separator The feed port is connected with the cru...

Abstract

The invention provides a dry cleaning and screening method and equipment system for bauxite, belonging to the technical field of a mining and mineral separation process. The method comprises the following steps: drying the bauxite into dry ore, breaking and separating the dry ore into ore and muddy silt, screening and separating the ore and the muddy silt to remove the muddy silt, and thus obtaining net bauxite. The structure of the dry cleaning and screening equipment system for the bauxite is as follows: an ore hopper is connected with a bauxite feeding opening of a drying roller through a conveying belt, and a discharging opening of the drying roller is connected with a feeding opening of an ore-mud separator; a coarse ore discharging opening of the ore-mud separator is connected with a crusher, and a discharging opening of the crusher is connected to the feeding opening of the ore-mud separator through a conveying belt. The method can realize the separation of ore and mud without water washing, so that the water resource is not wasted, sewage is not generated, and facilities for sewage treatment and tailings maintenance and preservation are not needed. The mud after ore washing can be completely recycled.

Description

【Technical field】 [0001] The invention relates to the technical field of mining mineral processing technology, in particular to a method and equipment system for dry cleaning and screening of bauxite. 【Background technique】 [0002] Accumulative bauxite is the main source of aluminum production in South China. Its typical feature is high mud content, accounting for about 60% of the original ore. During production and processing, about 60% of the clay in the raw ore must be removed by means of ore washing to obtain clean aluminum concentrate. At present, the process of water washing and crushing is generally used for the treatment of accumulation type bauxite, which consumes a lot of water resources in the production process, and the tailings produced need to be stored in special storage, which not only causes necessary water and soil erosion, but also has major risks. Security risks. The produced pure aluminum ore often affects subsequent processing and smelting due to exc...
