A squeezing roller granulator that has a squeezing roller pair composed of a toothed pressure roller and a toothed squeezing roller. The teeth of the pressure roller and the squeezing roller have tooth flanks that are situated between a tooth root region and a tooth tip region. The tooth root region has an outer diameter that is smaller than the outer diameter of the tooth tip region, and the tooth tip region of at least one of the rollers of the squeezing roller pair has three squeezing zones including a middle squeezing zone, which define different distances between the tooth tip regions with a minimum distance in the region of the middle squeezing zone, and the contour of the tooth flanks and the tooth root region of the rollers of the squeezing roller pair defines a maximum cross-section of granulate cushions to be formed.

An extrusion head having a perforated plate of a granulating system. The extrusion head can have a head part and a perforated plate with a perforated-plate wear insert, a perforated-plate main body, a central inflow cone, an inflow cone part, a plurality of nozzle channels, a plurality of perforated dies, and at least one corrosion protected fastener. The perforated-plate can be detachably fastened to the head part. The head part can have at least one central melt channel into which the inflow cone part projects and distributes a melt flow among nozzle channels which can be arranged in the shape of a ring and among the perforated dies which can be arranged in at least one ring. The at least one fastener can be positioned in a central region of the at least one ring of the perforated dies.

Apparatus for granulating strand materials including a stationary knife, a rotatable knife, and a drawing-in device. Part of the housing is pivotable to enable the drawing-in device to be easily removed for maintenance. An oblong hole on the housing is used to locate the drawing-in device.

Granulating device for strand materials

A strand caster, in particular for plastic strand casting systems, is provided, which in a known fashion consists of a nozzle plate and a caster. The nozzle plate and the caster include abutment surfaces facing each other, and the nozzle plate is mountable to the caster by corresponding mounting elements. The surface structure of at least one abutment surface of the nozzle plate or respectively the caster is adapted such that, due to the fastened state caused during operation, the one abutment surface accommodates to the opposing other abutment surface under tension so that an uniform surface pressing between the nozzle plate and the caster is achievable.

The invention relates to a granulation apparatus for strand material having pull-in apparatus for gripping the strand material and transporting it to a counter knife, a knife roll cooperating with the counter knife for cutting the strand material into granulate, and a housing accomodating the pull-in apparatus, the counter knife and the knife roll, wherein a motor driving the knife roll and the pull-in apparatus is arranged beside the housing and is connected by means of a drive axle to the rotating components contained in the housing, and wherein the motor and the housing are mounted on a common support. The mounting assembly includes two mounting devices which, in a projection onto the support, are arranged in the region of the two side portions of the housing which are beside said drive axle such that, due to the torque acting on the housing, the one mounting device (tension holding device) receives a tensile force away from the support and the other mounting device (the pressure holding device) receives a force of pressure against the support. The tension holding device, due to its hook-like formation, releasably holds the housing onto the support, and the pressure holding device is formed as a catch, thus preventing movement of the housing away from the tension holding device.
