The aluminum-plastic blister packaging of pharmaceuticals is also called blister packaging, or PTP packaging for short. It forms the film of the packaging material by heating vacuum forming or cold stamping to form grooves suitable for tablets, capsules, etc., and then fills it with medicine, and then heats it with aluminum foil coated with a heat-sealable coating. Sealed to form a unit package. Because of its huge consumption, a large amount of aluminum-plastic blister packaging waste is produced every year. If it is discarded directly, it will not only pollute the environment, but also cause waste of resources. Since it contains aluminum and plastic, it will generally pass through the relevant aluminum-plastic recycling equipment. , to completely separate the aluminum and plastic inside for reuse.

At present, recycling and reusing the waste aluminum-plastic medicine board is the method chosen by most people. The earlier recycling method used the chemical agent separation method, which added some chemical solvents to the water to remove the aluminum in the waste aluminum-plastic medicine board Separation from plastic through chemical reaction, although this method can achieve the purpose of resource recycling, but the phenomenon of wastewater pollution is also not easy to take, and the input cost is relatively high, and the effect of sorting is not very good.

At present, the relatively good aluminum-plastic separator adopts a new type of dry physical classification technology, which is different from the traditional aluminum-plastic separation method. In the separation process, it does not need to use water source and most of the heat energy heating method, and directly passes through the aluminum-plastic separation equipment for mechanical separation. Crushing, and then grinding the bulk material into powder by grinding for sorting, the sorting purity has reached more than 99%.

The principle of the aluminum-plastic separator is that the high-voltage static electricity generated by the high-voltage generator inside the equipment discharges to the grounded rotating roller, and the materials to be sorted are evenly lowered onto the rotating roller through a special unloading device. After the conductor material receives electricity, it is put into the ground through the grounding rotating roller, and the inertia of the rotating roller is added, and the conductor material is thrown into the conductor receiving hopper. After the non-conductive material is charged, due to its poor conductivity, it is adsorbed on the surface of the rotating roller, and as the roller turns to the back, it is swept by the brush and falls into the non-conductive hopper. Some of the conductive and non-conductive materials fall into the intermediate material receiving hopper due to different reasons such as the rotating speed of the roller, the adjustment distance of the equipment baffle, the size of the material particles and the amount of electricity received, and then enter the feeding machine and then enter the unloading device for sorting.

The aluminum-plastic separator crushes and decomposes the aluminum-plastic composite board into a mixture of aluminum and plastic, and then enters the high-voltage electrostatic separator to separate it into an environmentally friendly production process of aluminum and plastic. The whole process has no pollution, complete dry physical and mechanical decomposition and separation, and the metal recovery rate can reach more than 98%. Dual recycling of aluminum and plastic.
