Problems solved by technology

[0002] The method of crushing aluminum alloy mainly relies on mechanical crushing, so the crushed aluminum alloy often cannot reach the ideal particle size, and all processes adopt mechanical crushing, which not only consumes a lot of energy, but also produces a lot of dust during crushing to pollute the environment

Embodiment Construction

[0013] The detailed structure of the present invention is described in conjunction with the embodiments.

[0014] This includes the following steps:

[0015] A method for crushing an aluminum alloy, comprising the steps of:

[0016] (1), coarse crushing

[0017] Mechanical crushing method, and then react the raw materials with chemical substances, so that the particle size of the fragments is less than 4mm;

[0018] (2), broken

[0019] Place the coarsely crushed alloy blocks in an electric field. When the electric field lasts for 10 minutes, most of the alloy blocks will be further fragmented, so that the particle size is less than 2mm;

[0020] (3), screening

[0021] The broken alloy blocks are further screened, and can be divided into oversized and normal two standards for screening.

[0022] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples. Any changes, modifications, addit...

Abstract

The invention belongs to the technical field of metal materials and particularly relates to a method for crushing aluminum alloy. The preparation method comprises the following steps that (1) coarse crushing is conducted, a mechanical crushing method is adopted, then raw materials are subjected to reaction with chemical substances, and the particle size of fragments is made to be less than 4mm; (2) crushing is conducted, alloy blocks are placed in an electric field after the coarse crushing, after the electric field is kept for 10 min, most of the alloy blocks are further fragmented, and the particle size is made to be less than 2 mm; and (3) screening is conducted, the crushed alloy blocks are further screened, and the screening can be conducted according to two standards of oversized and normal. According to the method for crushing the aluminum alloy, the energy consumption and the pollution can be reduced. The method is low in energy consumption and free of pollution, and the requirement for the particle size is better met.

Description

technical field [0001] The invention belongs to the technical field of metal materials, in particular to a method for crushing aluminum alloys. Background technique [0002] The method of crushing aluminum alloy mainly relies on mechanical crushing, so the crushed aluminum alloy often does not reach the ideal particle size, and mechanical crushing is used in all processes, which not only consumes high energy, but also produces a lot of dust during crushing to pollute the environment. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a method for crushing aluminum alloys. [0004] The preparation method of the present invention comprises the steps: [0005] A method for crushing an aluminum alloy, comprising the steps of: [0006] (1), coarse crushing [0007] Mechanical crushing method, and then react the raw materials with chemical substances, so that the particle size of the fragments is less than 4mm; [0008] (2)...
