Abstract:
A chopping-grinding mill for used objects and other waste materials, in particular for motor vehicle tyres, comprises, in a single, compact work unit, a base (1), whereon a vertical-axis rotor (2) is rotatably mounted, said rotor (2) having the shape of a disc carrying a plurality of cutting blades (5, 6) fixed to the uppers surface thereof, to said rotor (2) a coaxial stator (3) being associated, in turn in the shape of a disc carrying a plurality of cutting blades (11, 12) fixed to the lower surface thereof, said stator (3) being mounted in a fixed position above the rotor (2) and at an adjustable distance therefrom, so as to define therewith a grinding chamber. Primary cutting blades (5, 11) extend from the centre to the periphery of said rotor (2) and stator (3) and secondary cutting blades (6, 12) extend only in correspondence of a peripheral crown of the rotor (2) and of the stator (3), while a feeding window (10) of the material to be ground is provided in the stator (3), in the area inside to said peripheral crown. The invention also comprises an automatic feeder for the controlled feeding of the material to be ground to said feeding window (10).

A disc-shaped coaxial stator (3) is associated with the rotor (2) and carries a plurality of cutting blades (II, 12) fixed to its lower surface. The stator (3) is fixed at an adjustable distance above the rotor (2), which together define a grinding chamber.
