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] Embodiment of the present invention: the bauxite particles of different grades transported from the mine are sent to the elevated distribution belt conveyor (1) that can travel back and forth, and the layered flat distribution is carried out. After a pile of materials is distributed, another layer is distributed. One pile; several stockpiles like stockpile (2) and stockpile (4) are laid out, and then bridge-type double bucket wheels (3) are used to take materials from the vertical section of each stockpile, and finally belt conveyor (5) The ore 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 flat-laying and straight-taking method for bauxite in alumina production. technical background: [0002] Alumina production requires that the grade of bauxite entering the production process (into grinding) should be relatively stable. The grades of bauxite are quite different in different mining areas, sections and even mining points of the mine, so it is necessary to mix ore ore ore. 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 Invention content: [0003] The purpose of the present invention is: the bauxite of different grades is transported from the mine, a...
