With the rapid development of industrial production and daily life, the recycling of metal waste has become more and more important. Among them, aluminum, as a lightweight, corrosion-resistant metal, plays an important role in the field of recycling. This article will briefly introduce the crushing and sorting process of aluminum chips to help readers understand the importance and operation steps of this process.

1. The source of aluminum chips Aluminum chips are mainly from aluminum processing enterprises, such as aluminum alloy manufacturing, aluminum product processing, etc. These enterprises in the production process will produce a large number of aluminum chips, these aluminum chips if not recycled, will cause resource waste and environmental pollution.

2. Purpose of aluminum debris crushing The purpose of aluminum debris crushing is to improve its recovery rate and utilization efficiency. By crushing, the aluminum chips can be converted into smaller particles, which are convenient for subsequent sorting and smelting.

3. Crushing process The crushing process of aluminum chips usually includes the following steps:

- Pretreatment: First of all, the aluminum scrap is cleaned to remove the oil and impurities on the surface.

- Crushing: Use a crusher to break the aluminum scrap into smaller particles.

- Screening: Particles of different sizes are separated by a screening machine to facilitate subsequent sorting.

4. Separation process Separation is a key step in the aluminum scrap recovery process, the purpose of which is to separate aluminum chips from other non-aluminum materials.

The sorting process usually includes:

- Magnetic separation: The use of magnetic separator to remove iron impurities.

Flotation: Separation of aluminum chips and non-aluminum materials by flotation.

- Air separation: The use of wind to separate light and heavy materials.

5. Smelting and reusing aluminum scraps after crushing and sorting can be smelted to make new aluminum products. The melting point of aluminum is low, and the energy consumption in the smelting process is low, which is conducive to energy saving and emission reduction.

6. Environmental protection and economic benefits The recycling of aluminum chips not only helps to reduce environmental pollution, but also saves resources and reduces production costs. With the improvement of environmental awareness, the market demand for aluminum scrap recycling is also growing.

The crushing and sorting process of aluminum scrap is an important part of metal waste recycling. Through this process, not only can improve the recovery rate of aluminum, but also promote the recycling of resources, to achieve a win-win situation of economic benefits and environmental protection.
