Problems solved by technology

[0003] The traditional aluminum powder production technology is melt spraying method, ball milling method, etc., but there is a problem, that is, there is a burning problem in the melting process of waste aluminum, which leads to a low metal recovery rate of about 92%, and the cost is relatively high. high

Abstract

The invention discloses a process of using aluminum skimming to prepare aluminum powder. The technological line of the process comprises: magnetic separation, pre-cleaning, pneumatic stirring, deep cleaning, separation of light impurities, centrifugal dehydration and residual oil removing, grinding, grading, secondary grinding, polishing and drying.

Description

technical field [0001] The invention relates to a method for producing aluminum powder from aluminum shavings. Background technique [0002] The production of aluminum powder from aluminum shavings is an important part of the secondary aluminum industry. Aluminum shavings need to be clearly classified and pre-treated to produce aluminum powder that meets relevant standards. There are many advantages in using aluminum shavings to produce aluminum powder. One is the high metal recovery rate, the other is high value, and the third is low cost. Therefore, the use of aluminum shavings to produce aluminum is a shortcut for the utilization of waste aluminum. However, it is worth pointing out that since most of the aluminum scrap exists in the alloy state, the aluminum powder produced is ordinary aluminum powder, which is mainly used for ferroalloy production, fireworks production, steelmaking and less demanding coatings. [0003] The traditional aluminum powder production technol...
