Abstract
A plastic granulator apparatus stationary cutting segment includes a segment rail having multiple arcuate spaced teeth. Each tooth of the plurality of arcuate spaced teeth has a tooth surface and is spaced to be complementary to a rotary cutter segments as a rotary cutter is rotated. The segment rail is adapted to be mounted to a granulator housing. The rail segment has a shoulder with a shoulder surface, the shoulder is adjacent to each of a set of arcuate spaced teeth. The shoulder has a shoulder surface height of between 0 and 10 mm, and a stepback distance of between 0 and 2 mm between the shoulder surface and the arcuate tooth surface. The shoulder and the arcuate tooth surface define an angle therebetween of 90° and 130°, and the shoulder surface defines an angle between 90° and 130°.
