Abstract
A crushing device includes a casing with an inner wall, a rotor having a vertical axis of rotation, mounted in the casing and formed by a disk having a working surface with radially arranged fractionating blades mounted thereon and each including a working lateral face and a lateral face opposite to said working lateral face and each consisting of a main portion rigidly secured relative to the rotor disk and located nearer to the rotor axis and a peripheral portion pivoted to the rotor disk, rotatably mounted about the vertical axis, and having a section radially extending beyond said disk, and stationary grinding elements placed on the inner wall of the casing and arranged coaxially with the rotor disk. The stationary grinding elements appear as projections facing the rotor axis and are located above the sections of the peripheral parts of the blades extending beyond the disk, and spaced from the working surface of the rotor disk by a distance corresponding to the predetermined maximum size of the pieces of material in the final crushed product, said projections being arranged in a spaced relationship radially to the rotor disk. In addition, the device comprises a rotor drive.
