Abstract
An apparatus for processing thermoplastic synthetic plastic material includes a receptacle in which a rotating tool circulates around an axis. The axis of rotation may be offset with respect to the axis of the receptacle by a predetermined amount. From the receptacle, the comminuted material is conveyed by the rotating tool into the inlet opening of a screw-type extruder which has an axis that is offset relative to a parallel radius of the receptacle. The offset arrangement allows the rotating tool improves the flow of the processed material into the screw-type extruder.
Claims7
An apparatus for processing synthetic plastic materials comprising:
- a receptacle having a bottom wall, a side wall, and a substantially vertical axis;
- a rotating tool disposed within the receptacle, said rotating tool disposed adjacent said bottom wall and adapted to rotate in a rotation direction about a rotation axis substantially parallel to said vertical axis;
- and
- an output device adapted to remove processed material from said receptacle, said output device including an output housing attached to an opening defined in said side wall and a output screw disposed within said output housing, said output device being substantially disposed on the exterior of the receptacle;
- said output housing having a longitudinal axis intersecting said receptacle at a point, said point and said rotation axis of said rotating tool defining a first radius therebetween;
- said first radius being offset by an angle of between approximately 5.degree. and 20.degree. relative to a second radius, said second radius being parallel to the longitudinal axis of said output housing, said offset angle being in the opposite direction relative to said rotation direction;
- whereby said output device is filled with processed material by a component of a peripheral vector, measured in an axial direction of said output screw.
