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°.

A cutter head for an underwater granulating installation has a rotor body having a plurality of cutter-retaining arms. Each of the plurality of cutter-retaining arms adjoins the outer circumference, and one cutter element is fastened on each of the plurality of cutter-retaining arms, where the rotor body in the region of each cutter-retaining arm includes at least one receptacle recess configured to receive a fastening element. The cutter element is integrally configured to have a basic body and at least one blade body. The basic body is positioned on a lower bearing face of the rotor body, and the lower bearing face extends up to at least one of the plurality of cutter-retaining arms. The at least one of the plurality of cutter-retaining arms on an upper side is overlapped by the cutter element, and the blade body includes at least one cutting edge molded thereon.

A comminuting apparatus adapted to carry out a comminuting process comprising a comminuting rotor which is mounted to a machine frame and which has a plurality of comminuting tools at its periphery, wherein the comminuting rotor is arranged in a comminuting chamber for receiving comminution material and is adapted to comminute the material in the comminuting chamber, further including a cooling device adapted to introduce a liquid coolant including at least 80% water into the comminuting chamber and including a control device for controlling the cooling device to set a rate of introduction of the coolant into the comminuting chamber. The comminuting apparatus according to the invention is distinguished in that the control device is designed and configured to adapt a rate of introduction of the liquid water-based coolant into the comminuting process to an operating parameter of the apparatus, that is dependent on the quantitative throughput of the comminution material, in such a way that more than 60% of the cooling capacity introduced into the comminution material is provided by the latent heat of the liquid water-based coolant. The invention further concerns a method of operating an apparatus.

The invention relates a device for suctioning off waste products of the production machine comprising a suction chamber at which at least a suction element is assembled which extends into a suction space, which is outside the suction chamber in order to convey waste products into the suction chamber, wherein the suction element comprises an inlet area, which is facing the suction space and an outlet area, which ends in the suction chamber.

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 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.
