The bags opener machine has been designed and manufactured to open bags or other kinds of containers usually used to collect M.S.W. The opening of the bags is assured by the circular motion of a drum equipped with retractile teeth and by a contrast comb.
The rotor’s sharp tools, made of wear resistant material, reach the maximum point of amplitude in the material receiving section (conveyed by a chain metal plates conveyor) and re-entering on the rotor in the discharge side. The motion is by means of a hydraulic unit and by a variable control motor pump, therefore the applied power is always proportional to the type of material to be processed. So the rotation speed is easily variable according to the quantity of the processed material.
