Polishing and screening equipment for aluminum slices

Abstract

The invention discloses polishing and screening equipment for aluminum slices. The polishing and screening equipment comprises a feeding hopper, a chain scraper conveyor, a polishing drum, a suspension magnetic separator and a screening drum. According to the polishing and screening equipment for the aluminum slices, the polishing drum rotates and stirs, so that materials are automatically rubbed in the drum, the polishing effect is generated, impurities on the surfaces of the materials are reduced, and certain surface purity is achieved; iron-containing impurities are screened through a magnetic hanging magnetic separator, the iron content in an aluminum raw material is reduced, aluminum water components are purified, and the recovery rate is increased. Therefore, the polishing and screening equipment for the aluminum slices has the advantages of high recovery rate and high recovery purity.

Description

technical field [0001] The invention relates to an aluminum slice polishing and screening equipment, in particular to an aluminum slice polishing and screening equipment with high recovery rate and high recovery purity. Background technique [0002] The recycled aluminum industry must meet the existing standard requirements before entering the domestic market. The scrap aluminum that has not been polished needs to be washed and screened to wash off the mud powder on the surface of the scrap aluminum; this requires the use of a large amount of water resources, which not only wastes water resources, and their production efficiency is still low. [0003] Moreover, the recovered aluminum flakes contain other impurities such as iron, which cannot be screened by existing recycling equipment, resulting in low purity and low recovery rate of the recycled aluminum flakes. [0004] Therefore, it is necessary to propose an improvement to overcome the defects of the prior art. Conten...
