This equipment adopts dry physical separation technology and completes aluminum-plastic separation through four steps: crushing, grinding, screening, and electrostatic sorting. Firstly, the discarded aluminum-plastic products are initially crushed to below 4mm by a crusher, and then ground into a 24 mesh powder by a water-cooled grinding machine to prevent the material from melting due to frictional heating. After selecting qualified particle size through a rotary vibrating screen, the double roll shaft electrostatic sorting machine utilizes the difference in conductivity between aluminum and plastic to achieve high-purity separation of over 99% between the two. The entire process does not require chemical solvents, and the equipped three-stage dust removal system (cyclone dust removal+bag dust removal+air purifier) can effectively control dust pollution.
The efficiency and adaptability of the equipment are particularly outstanding. The equipment developed by Zhengzhou Asia Pacific Energy Environmental Protection Technology has a daily processing capacity of several tons to tens of tons per unit. The separated aluminum purity exceeds 95%, and the plastic impurity content is extremely low, which can be directly used as recycled raw materials in the production process. In the pharmaceutical industry, discarded drug boards can be processed and aluminum can be recycled for further refining, while plastic can be used to manufacture new packaging; The discarded aluminum-plastic panels in the field of building materials, separated aluminum profiles, and plastic substrates can be used separately for the production of building materials.
In terms of environmental benefits, the equipment significantly reduces pollution through resource recycling.
With the advancement of the “dual carbon” goal, aluminum-plastic separation and recycling equipment is becoming the core equipment in the field of resource recycling. Its low energy consumption, high return characteristics (investment return cycle of 6-12 months) and wide applicability (covering the entire industry chain of pharmaceuticals, food, building materials, etc.) have enabled it to quickly popularize with policy support. As industry experts have said, “This equipment is not only an environmentally friendly tool, but also a printing press for resource regeneration.” In the future, with technological iteration, aluminum-plastic separation and recycling equipment will surely promote the circular economy to a new height.
