Explain the environmentally friendly separation process and working principle of aluminum-plastic separation and recycling equipment

There are a large number of food packaging bags and aluminum-plastic packaging such as beverage bottles and tablet boards on the market. The main components of these aluminum-plastic packaging products are a mixture of plastic film and aluminum foil. The environmentally friendly aluminum-plastic separation and recycling equipment crushes, grinds and separates different packaging materials more cleanly and thoroughly. It uses physical and mechanical methods to crush waste aluminum-plastic packaging products into granules or powder. According to the conductive characteristics of aluminum and plastic, an electric field is used to make the material The environmentally friendly separation process and working principle are as follows:

1. The environmentally friendly separation process is roughly: crushing, crushing the metal and plastic composite into pellets; grinding and decomposition, grinding the pellets into a metal and plastic mixture; electrical separation, electrically selecting the metal and plastic mixture Separate into metal and plastic; the purity rate of the separated aluminum chips can reach more than 99%.
2. Use a grinder to grind the waste materials into particles of a certain size (to avoid the high temperature generated from affecting the efficiency of plastic and aluminum). Shear forces separate the aluminum and plastic particles.
3. Since aluminum is a conductor with good electrical conductivity, and plastic is not a conductor, when the mixed particles of aluminum and plastic fall into a rotating grounded roller, and a high-voltage electrode is fixed above the roller to provide a stable state for the crushed particles. of the electric field, the aluminum and plastic particles are polarized simultaneously. When they leave the electric field area, the aluminum particles will quickly lose their charge, while the plastic particles still carry the charge. Under the action of centrifugal force and gravity, the aluminum particles are thrown out of the roller, and the plastic particles fall along the roller.

Working principle: After the medicine board enters the crusher, it becomes pieces of less than 10mm, and then enters the high-speed water-cooled turbine pulverizer to cut the material into fine pieces. The materials that meet the requirements are screened by the rotary vibrating screen. The principle of the ceremonial electrostatic separator separates aluminum and plastic, and the unqualified materials are returned to the grinding mill to repeat the process. The loss of aluminum and plastic is very low, and the recycling rate of aluminum is close to over 99%. And it will not cause secondary environmental pollution. The aluminum particles separated by the aluminum-plastic separation and recycling equipment can even be sold directly, with good economic and social benefits.

Aluminum plastic separation and recycling equipment environmentally friendly separation method. The successful separation of aluminum and plastic can separate 0.65-0.85 tons of plastic and 0.33-0.13 tons of aluminum per ton of waste aluminum and plastic. No secondary pollution is produced during the separation process. Industrial waste can be fully regenerated. Utilization not only saves a lot of material resources, but also protects the environment and generates considerable economic benefits. Aluminum plastic separation and recycling equipment
