UNIT FOR CUTTING WITH GRINDING, INTENDED FOR CONVERSION OF SOLID OR DIVIDED INTO LARGE PIECES OBJECTS INTO GRANULES, AND IN PARTICULAR, SOLID USED TIRES, AND IMPROVED FEEDING DEVICE FOR SUCH UNIT Russian patent published in 2017 - IPC B02C7/08 B02C23/02 

FIELD: recycling.

SUBSTANCE: group of inventions is intended for chopping with used objects and other wastes grinding, in particular, car tires. Unit in form of single compact working unit consists of base (1) and rotor (2) with vertical axis. Rotor and stator (3) are made in form of discs with plurality of cutting blades (5, 6, 11, 12) attached to their upper and lower surfaces. Stator and rotor (2) are connected coaxially. Stator is installed in fixed position above rotor (2) at controlled distance. Stator limits grinding chamber. Primary blades (5, 11) extend from center to periphery. Secondary blades (6, 12) are spread only in peripheral crown. Stator feed window (10) at least partially opens into primary blades coverage area. Automatic feeding device comprises pair of rolls with parallel axes. Rolls are arranged next to each other (15, 16) on frame (13). Frame forms integral part with unit in accordance with feeding opening. One of rolls axis of rotation is resilient movable relative to rotation axis of other one in perpendicular direction (F).

EFFECT: enabling continuous tires loading into unit and reduction of occupied working space.
