Shredding machine with washer and drier

Machine for cutting up and shredding broad pieces of material, made particularly of synthetic resin, and for subsequently washing and drying said shredded material, characterized by the fact that the machine comprises, placed in series, two devices, one of which cuts up and shreds said material, and the second of which washes thoroughly and subsequently partially dries said shredded material in a first part thereof, and then in a second part of the second device completes the drying of said shredded material commenced in the first part, wherein said one device comprises:

• a drum rotating inside a basket carried by a containment barrel in such a way as to form a hollow space in between said basket and said barrel, said basket being provided with an inlet for the material to be processed and an outlet for the processed material, in opposite terminal areas;
• a device for moving the ingoing material towards said inlet;
• at least a first set of cutter blades fixed to the rotating drum and so placed as to be uniformly distributed over the circumference thereof in the region of said inlet, with their cutting edges inclined with respect to the axis of said drum in such a way as to cause the material, as it is gradually cut up, to move towards said outlet;
• at least a second set of cutter blades fixed to the rotating drum, following on after said first set of blades in such a way as to be distributed over the circumference of said drum, with their cutting edges perpendicular to the axis thereof;
• at least one set of beaters fixed to the rotating drum, following on after said second set of blades, these also being distributed uniformly over the circumference of the rotating drum and inclined with respect to the axis thereof in such a way as to cause the material, as it is gradually beaten, to move towards said outlet;
• first, second and third contrast elements fixed to said basket and designed to operate in contrast with said first and second set of blades and with said beaters fixed to the drum;
• and at least one impeller, following on after said set of beaters in the region of the outlet, fixed to the drum and able to remove the cut up and beaten material from the basket and to channel it into a connecting duct that runs into the entry point to said second device.
