Problems solved by technology

The original method is to transport the bauxite of different grades from the mine to the ore blending yard in the factory area, and then carry out the ore blending. This not only requires a considerable amount of heavy-duty dumping equipment and occupies a large area; but also the workload of the ore blending is large , poor working conditions and the impact on the factory area and the surrounding environment

Embodiment Construction

[0009] The embodiment of the present invention: send the bauxite particles of different grades from the mine to the overhead cloth belt conveyor (1) that can walk back and forth for layered and flat cloth. One pile; arrange several piles like piles (2) and piles (4), then use bridge type double bucket wheels (3) to take materials from the vertical section of each pile, and finally use belt conveyors (5) The mineral material is sent to the grinding system for grinding.

Abstract

The invention discloses a method for using aluminiun mine during aluminum oxide preparation process. It employs tiling, distributing material and fetching material way, that is to send alumyte particle got from mine to cloth device walking back and forth such as overhead cloth belt for tiling and distributing one by one; then fetches material with bridge double-hopper wheel from its vertical section; and sends it to grinding system with convey device such as belt. The invention not only meets demand of distributing mineral in aluminum oxide prepartion process, but also overcomes problems of needing mang heavy deliervy equipment, taking up large area, large amount of work for mineral distributing and bad working condition.

Description

Technical field: [0001] The invention relates to a method for flat-laying, straight-taking and homogenizing bauxite in alumina production. technical background: [0002] Alumina production requires that the grade of bauxite entering the production process (into the mill) should be relatively stable. The grade of bauxite varies greatly in different mining areas, ore sections and even ore sites, so ore must be blended or homogenized. The original method is to transport bauxite of different grades from the mine to the ore distribution yard in the factory area, and then carry out the reverse transportation and ore distribution. This not only requires a considerable amount of heavy-duty transportation equipment and a large area; but also a large amount of ore distribution work. , Poor working conditions and impact on the plant and surrounding environment. Summary of the invention: [0003] The purpose of the present invention is to transport bauxite of different grades from the mine,...
