The invention describes a blade mill for grinding plastic material with a rotor which is driven in rotation inside a grinding chamber and has a plurality of radially outwards-pointing cutter blades distributed around its circumference and a plurality of stationary, radially inwards-pointing stator blades projecting into the grinding chamber and forming a blade gap with the cutter blades, wherein cutting spaces widening radially outwards in a crescent shape and located radially outside the turning circle of the rotating cutter blades are located ahead of the stator blades in the direction of rotation of the rotor. To prevent the plastic material which is to be ground from backing up in the cutting spaces and from being crushed against the wall of the screen baskets, the invention provides that the motion path of the rotor blades extend eccentrically with respect to the axis defined by the screen baskets. Relaxation spaces in which the plastic material is accommodated and which extend over a large rotational angle of the rotor blades are thereby formed in the gap between the wall of the screen baskets and the orbital path of the rotor blades. This allows the driving power of the drive motor to be significantly reduced for a given cutting performance.

A primary reduction apparatus having a frame structure and at least one shaft mounted on the frame. The shaft is reversibly rotatable around an axis of rotation in a first direction of rotation or a second direction of rotation. A drive supplies rotation force to rotate the shaft. Protruding cutters are arranged on the shaft, each cutter having a stem portion which edges define shear edges, a first protruding wedge-shaped tooth arranged on the stem portion and facing the first direction of rotation and a second protruding wedge-shaped tooth facing the second direction of rotation. Cross members connect sides of the frame with cracker jaw plates removably attached to each cross member. The cracker jaw plates have a working surface with multiple pierce points forming a serrated edge to cooperate with the cutters. The cracker jaw plates have a relief on a surface of the cracker jaw plates facing the cutter and are removably attached to the cross members. The cross-members are similarly removably attached to the frame. The frame structure has an enclosure provided with a charging opening for material to be shredded, and a discharging opening for shredded material. The drive has either an internal combustion engine or an electric motor used as prime mover. The prime mover provides pressurized hydraulic fluid to a hydraulic motor, which provides the rotation force to the shaft. A pressure sensing means is connected to the drive to automatically reverse the shaft rotation directions when the pressure sensing means senses an over-pressure situation. The drive has a timer to periodically reverse the shaft rotation direction. A plurality of vertically extendible and contractible legs are attached to the frame and provide support for the shredding apparatus during shredding.
