The machine has a rotor that spins at a low rev speed, working by means of an electric motor. The transmission system of the motor to the rotor is formed of a belt and a planetary type gear unit. The speed of the spinning rotor can be controlled by means of a frequency variator (from 0 to 12 rpm).
The rotor includes a series of piercing teeth, in the form of a spiral and along the whole surface, which open the bags by tearing them with fixed teeth. The distance between the teeth of the rotor and the static piercing machine is adjustable between 5mm and 150mm.
It is a very effective machine for opening bags (more than 95%) which, avoiding the need to be aggressive with their contents, increases the efficiency of any selection and recovery process of recyclable materials.
