摘要： A device for filtering a plastic melt, including a housing and a filter pin which is axially and/or radially movable therein. In a working position of the filter pin, plastic melt passes from an inlet channel, through a filtering mechanism, which is detachably fastened to the filter pin, to an outlet channel. In a filter change position of the filter pin, the filtering mechanism is freely accessible for replacing the filtering mechanism, and wherein at least one drainage channel is formed in the filter pin. In a start-up position of the filter pin, one end of the at least one drainage channel is in fluid connection with the at least one inlet channel in order to receive the plastic melt that is fed through the at least one inlet channel and to output the plastic melt at another end of the at least one drainage channel.

摘要： A cutting chamber housing for an underwater pelletizer having an inlet for cooling fluid and an outlet for cooling fluid with pellets. The cutting chamber housing encloses a cutting device having a rotary drive and a cutting head with rotating cutting knives. An extrusion head having a perforated plate projects into the cutting chamber housing. The cutting chamber housing has a stationary upper housing half and a movable lower housing half along a separation plane arranged at an oblique angle so that the cutting chamber housing can be opened at least downwards along the separation plane. Features such as slide rails, swivel joints, or rotary joints can be added to enable easy opening of the cutting chamber housing.

摘要： 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.

摘要： A granulating device having a cutting knife head for cutting strands of melt into granules in a granulator housing. A perforated plate with die openings, from which strands of melt is extruded into the granulator housing, projects into the granulator housing. The cutting knife head, which has at least one cutting knife arranged radially on its outer circumference, is driven by a rotating drive shaft. The granulator housing has a first coolant inlet and an outlet for a mixture of coolant and granules. In addition, the granulator housing has a second coolant inlet that is independent of the first coolant inlet and that supplies a coolant flow for direct granule cooling to at least one co-rotating cooling nozzle bore in the cutting knife head through a coolant chamber and a stationary coolant pipe oriented coaxially to the drive shaft.

摘要： A device and method for producing pellets from a melt material, the device having a perforated plate with nozzles. Located opposite the perforated plate is a cutter arrangement having a cutter head with at least one blade, wherein the device additionally has a cutting chamber in a housing. A coolant is introduced into the cutting chamber from an inlet apparatus, wherein one or more additional feed opening(s) is/are provided for an additional flow of coolant to the cutting chamber. The additional coolant flows at least in the area of rotation of the at least one blade, circumferentially at least in sections, with an orientation such that this additional flow of coolant differs from the flow of coolant entering through the inlet nozzle arrangement in at least one of the following parameters: physical state, direction, speed, pressure, temperature, density, throughput rate, and/or composition.

摘要： 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.
