There are various machines and technologies available to separate plastics from aluminum in pharmaceutical blisters. One common method is the use of mechanical separation techniques, such as:

Shredding and sieving: The blister packaging can be shredded into smaller pieces using a shredding machine. The resulting mixture of plastic and aluminum fragments can then be passed through a series of sieves or screens with different mesh sizes. The different sizes of particles allow the plastics and aluminum to be separated based on their size and shape.

Air classification: This method utilizes air currents to separate the lighter plastic particles from the heavier aluminum particles. The shredded blister material is introduced into an air classifier, which blows air upward. The lighter plastics are carried upward by the air currents while the heavier aluminum falls down, allowing for effective separation.

Eddy current separation: This technique utilizes magnetic fields to separate aluminum from plastics. The shredded blister material is passed through a conveyor belt equipped with a magnetic field. The aluminum, being non-magnetic, is repelled by the magnetic field and diverted into a separate collection container, while the plastics continue along the conveyor belt.

Electrostatic separation: This method utilizes the difference in electrical conductivity between plastics and aluminum to achieve separation. The shredded blister material is charged with static electricity, and then passed through an electrostatic separator. The charged plastics and aluminum particles are attracted to or repelled by electric fields, allowing for their effective separation.

It's important to note that the effectiveness of these separation techniques can vary depending on the specific composition and characteristics of the blister packaging. Additionally, some machines may combine multiple separation methods to achieve optimal results.

When considering the investment in a machine for separating plastics from aluminum in pharmaceutical blisters, factors such as processing capacity, efficiency, maintenance requirements, and cost-effectiveness should be taken into account. It's advisable to consult with manufacturers or suppliers of such equipment to explore the available options and choose the most suitable machine for your specific needs.
