| 20100081363 | DEVICE FOR MACHINING A DIE PLATE OF AN EXTRUDER - Methods and devices for machining a die plate of an extruder for pelletization are provided. The device can include a grinding wheel with a grinding surface rotatably disposed on a drive mechanism of a cutter head associated with the extruder. The grinding surface can include a hard coating aligned with the die plate. | 04-01-2010 |
| 20100289166 | DROP PELLETIZING DEVICE AND METHOD FOR THE OPERATION THEREOF - A drop pelletizing device and method for producing pellets from a low-viscosity plastic melt are provided. The drop pelletizing device can include a die plate with holes, in which the plastic melt can be subjected to a harmonic pressure oscillation such that the plastic melt emerging from the holes forms individual pellet droplets, a pressure vessel, in which prevails an overpressure above the ambient pressure, a discharge device adapted to discharge the individual pellet droplets from the pressure vessel and to reduce the overpressure, a separator adapted to separate the individual pellet droplets from the coolant; and at least one circulating device adapted to agitate the coolant to separated and unclump the individual pellet droplets in the coolant and for producing turbulence within the coolant. | 11-18-2010 |
| 20110061261 | DRYING APPARATUS FOR DRYING PELLETS - One or more embodiments of a drying apparatus for drying pellets from a process fluid are provided. The drying apparatus can include at least one screen device. The at least one screen device can have a screen area with screen openings. The drying apparatus can also have an oscillating device that sets at least the screen area of the screen device into oscillation. The oscillations can move the pellets relative to the screen openings, and the process fluid can drain off through the screen openings. | 03-17-2011 |
| 20110062262 | SHREDDER FOR PRODUCING PARTICLES FROM A SHEET MATERIAL - A shredder for producing particles from a sheet material is disclosed herein. The shredder can have a longitudinal cutting device with a first cutting roller and a second cutting roller. A transverse cutting device can be positioned after the longitudinal cutting device. The first cutting roller and the second cutting roller can each have special profiles. | 03-17-2011 |
| 20110215494 | DEVICE AND METHOD FOR CONTINUOUS CASTING AND GRANULATION OF STRANDS FROM THERMOPLASTIC - The invention relates to an apparatus for continuous casting and granulating strands of a thermoplastic material which uses a nozzle head having a plurality of nozzle apertures of a maximum diameter of 4 mm each, and water-moistened guide means for cooling and guiding the plastic strands exiting the nozzle aperture via inlet rollers to the inlet of the cutting unit for chopping up the plastic strands into granules approx. 2-3 mm in length. The flow rate of the melt, with the strands being cooled down on their way from the nozzles via the guide means to the feed rollers of the cutting unit, of at least 100 nm/min in the central spatial region of the nozzle apertures will be increased to such an extent that the cutting unit will chop up the strands at a cutting rate of >2,000 cuts/s. | 09-08-2011 |
