The device is designed to break the compressed beverage cans and not to tear them, so that they can be reused after further recycling. The device itself can be moved around on site as it is transportable. It can also be mounted as a fixed installation in one place. It consists of a shredder and a conveyor belt. Each of the units can be guided in both directions (forward and backward). The speed of the blades of the pre-shredder can be frequency controlled.
