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 135, and the shoulder surface defines an angle between 90 and 135.

A screen for a shredder machine has a shape that avoids clogging of the materials being processed through the shredder. The screen has a pair of mounting plates that are connected to the shredder with one mounting plate attached toward the top of the rotor and the other mounting plate attached toward the bottom of the rotor and extending the entire length of the rotor. Arcuate ribs are attached to and extend between the mounting plates, and a grid is attached to the ribs.

Granulator mill (1) comprising a frame (10), a cutter housing (20) with a granule chamber (22) comprising at least one non-rotatable blade (24) inside the granule chamber (22), and further comprising a rotatable rotor (30) arranged inside the granule chamber (22). The rotor (30) comprises blades (32, 34) which are arranged for cooperation with the non-rotatable blade (24) for granulating waste material to granules. A normal (n) to a first opening (26a) of the granule chamber (22) is pointing substantially vertically upwards in the normal position of use of said granulator mill (1), and characterising is that the cutter housing (20) is pivotably arranged at the frame (10) by means of a first pivot means (28), for pivoting the cutter housing (20) between the normal position of use and a cleaning position. In the cleaning position, the normal (n) of the first opening (26a) of the granule chamber (22) points towards a surface plane of the substrate.

A method for manufacturing micronized rubber powders including grinding of a rubber granulated feedstock, size classification and storage of the micronized rubber powders thus obtained. A rubber formulation including at least one natural or synthetic rubber, a micronized rubber composition and optionally one or more of processing aids, antidegradants, fillers, accelerators and curatives. A method for manufacturing a rubber product, as well as to a solid rubber product.

A strand pelletizer for pelletizing a strand of material comprises at least one cutting edge and an opposite cutting edge. The opposite cutting edge is arranged on a base body which is displaceable relative to a support body. The base body is independently displaceable in a linear manner relative to the support body and pivotable about at least one pivot axis. The strand pelletizer enables simple and precise adjustment of the opposite cutting edge and an associated cutting gap.

A strand pelletizer for pelletizing strands such as strands of plastic material into pellets, having a cutting mechanism which has a rotationally drivable cutting rotor and a stationary counter-knife cooperating therewith, wherein a cutting gap is formed between a cutting edge of the stationary counter-knife and rotor tooth tips of the cutting rotor. During operation of the cutting mechanism on the stationary counter-knife there is provided at least one sensor for determining a gap dimension of the cutting gap.

A strand pelletizer for pelletizing strands such as strands of plastic material into pellets, having a cutting mechanism which has a rotationally drivable cutting rotor and a counter-knife cooperating therewith, wherein a cutting gap is formed between a cutting edge of the counter-knife and rotor tooth tips of the cutting rotor. A cutting gap adjustment apparatus with a cutting gap adjustment drive is provided for adjusting the gap dimension of the cutting gap during operation of the cutting mechanism.

A feed device and a strand pelletizer including the feed device and a cutting mechanism having a rotationally drivable cutting rotor and a counter-knife cooperating therewith. The feed device has a pair of feed rollers rotatable in opposite directions in order to feed strands to the cutting mechanism. At least one of the feed rollers is mounted transversely to a longitudinal axis of the mounted feed roller in a movable manner by a movable roller suspension. An adjustment actuator linked to the movable roller suspension can be used to adjust a gap between, and/or the contact force between, the feed rollers. The adjustment actuator has an articulation point on the movable roller suspension and an articulation point on a cutting mechanism support on which the cutting rotor is mounted, so that the movable roller suspension and the cutting mechanism support are directly connected by the adjustment actuator.
