The Bales Opener machine has been designed to open bales of PET bottles for separating them without breaking them. In this way single and pressed bottles are ready to be controlled and sorted by the sorting systems. The hopper can be fed with a whole bale of product, conveying it to the rotor that “scrapes” the bottles thanks to a particular structure and to a clockwise and counter-clockwise rotation. The bottles are then conveyed to a discharging hopper suitable to charge them to the next conveyor belt.
