Start the entire process, and after washing with water, the raw materials are transported to the first flotation stage. At this stage, the diameter of the main drum used for flotation is 2.6 meters, and a heavy medium is added to it to create a 2.0 density environment in the chamber. Under this specific condition, substances such as aluminum with adhesive, sponge, and high magnesium material can be separated from the raw materials.
After completing the first stage flotation, the material immediately enters the second stage flotation step. Also equipped with a main engine bucket with a diameter of 2.6 meters, but the density of this level of warehouse is adjusted to 3.0. Taking advantage of this density difference, aluminum and copper zinc materials are separated.
After two stages of flotation, the product enters the final stage of classification and collection. Depending on the density, the products are classified into three compartments:
Low density warehouses are used to store magnesium alloys, as well as lightweight materials such as rubber, plastic, and wood;
The medium density warehouse is specifically designed to collect aluminum;
High density warehouses gather high-density mixed non-ferrous metals such as copper and zinc.
