  • Disintegrator having grinding chamber with rotors including carrying disk with grinding wheels concentrically arranged thereon
    Patent number: 4813619
    Abstract: A disintegrator comprises a housing (1) and a grinding chamber (2) accommodating grinding wheels mounted on shafts (9, 10) of electric motors. The peripheral zone of the chamber (2) accommodates inclined plates (13) of a classifier arranged about the circumference so that an annular slot (14) is formed between these plates and a cylindrical portion (3) of the chamber (2) through which the chamber (2) communicates with a separator (15). The separator (15) embraces one of the electric motors (11) and communicates by way of a passage (21) of return flow of air with an air distributor (22) embracing the electric motor (12). The distributor (22) is connected to the chamber (2) by way of annular slot (24) between the plates (13) of the classifier and the last grinding wheel (8) of the rotor. Connected to the separator (15) is a collector (18) of fine fraction of the material.
