20100330216 | System for controlling cutter hub position in underfluid pelletizer - A cutter hub position control device for consistent blade adjustment in an underfluid pelletizer is provided in connection with a motion rod attached to the pelletizer cutter hub and extending through a hollow shaft of the pelletizer motor. The cutter hub position control device can be collinear, transaxial or in a plane parallel to the axis of the motion rod to which it is attached. Adjustment of the cutter hub position control device is automated through use of feedback control mechanisms. | 12-30-2010 |
20140175695 | MELT PROCESSING PLANT - The present invention relates to a melt processing plant, comprising a melt charger for charging a processing head, in particular palletizing head, with melt, wherein upstream of the processing head a diverter valve for discharging the melt during a starting and/or retooling phase is associated to the melt charger, and to a method for melt processing in such melt processing plant. In accordance with the invention, a portioning device for portioning the discharged melt into melt portions is associated to the diverter valve, wherein a cooling device for cooling the melt portions to at least partly solidified chunks of material is provided. | 06-26-2014 |

20100255135 | PELLETIZING DEVICE AND BLADE HEAD AND/OR GRINDING HEAD FOR SUCH A PELLETIZING DEVICE - The present invention relates to a pelletizer, preferably in the form of an underwater pelletizer. In particular, this invention relates to a cutter and/or grinding head for such pelletizer, comprising a tool carrier which can rotatorily be driven about a tool carrier axis of rotation, and at least one cutting and/or grinding tool, which is attached to the tool carrier and is spaced from the tool carrier axis of rotation, for knocking off plastic melt emerging from a pelletizer die plate and/or for grinding said pelletizer die plate. In accordance with the invention, the cutting and/or grinding tool is rotatably mounted on the tool carrier about an axis of rotation spaced from the tool carrier axis of rotation. This provides a second component of movement for the cutting and/or grinding tool. On the one hand, the cutting and/or grinding tool rotates together with the tool carrier about its tool carrier axis of rotation, and on the other hand, the cutting and/or grinding tool can rotate about its own axis of rotation relative to the tool carrier. The tool carrier has a pivot bearing for the cutting and/or grinding tool, by means of which the cutting and/or grinding tool can rotate about itself. | 10-07-2010 |

20100037477 | CENTRIFUGAL DRIER - The present invention relates to a centrifugal dryer for the separation of pellet-like substances from process water, comprising a housing, a rotor arranged in the housing and a screen surrounding the rotor at the peripheral side, with the screen having at least one porous screen member which is placed in an arcuate manner around at least one screen carrier hoop and is releasably fastened thereto. In accordance with the invention, the screen is composed of a plurality of screen members which mutually overlap in the peripheral direction and are clamped tight to the screen carrier hoop by one or more tension belts which wrap around the mutually overlapping screen members at the peripheral side. Generally, differently made pliable, flexible and/or resiliently flexible tension members can be wrapped around screen members as a tension belt which are clamped and hereby hold the screen members together. | 02-18-2010 |

20090115091 | Method and Device for Granulating Plastics and/or Polymers - The present invention relates to a method for the pelletization of plastics and/or polymers, wherein a melt coming from a melt generator is supplied via a diverter valve having different operating positions to a plurality of pelletizing heads through which the melt is pelletized. The invention furthermore relates to a pelletizing apparatus for the pelletization of plastics and/or polymers having a diverter valve which has at least one melt generator connection, at least two pelletizer connections as well as a switching gate for selectively connecting the melt generator connection to at least one of the pelletizer connections, with a respective pelletizing head being connected to the at least two pelletizer connections and a melt generator having a variable melt volume flow being connected to the melt generator connection. Finally, the invention also relates to a diverter valve for such a pelletizing apparatus having a melt generator connection, a pelletizer connection as well as a melt passage for the connection of the melt generator connection to the pelletizer connection. The present invention therefore starts from the idea of using a plurality of pelletizing heads with different passage capacities and of hereby enlarging the throughput window to be able to work largely continuously without intermediate interruptions and to shorten unavoidable start-up processes by switching in pelletizing heads having small throughput capacities or to minimize them with respect to the start-up products which occur. In accordance with an aspect of the present invention, a plurality of pelletizing heads having different throughput capacities are used sequentially for the start-up of the pelletizing process, with the melt first being supplied to a first pelletizing head having a smaller throughput capacity and then the melt volume flow being increased and the diverter valve being switched over such that the melt is diverted by the diverter valve to a second pelletizing head having a larger throughput capacity. The time and thus the amount of the start-up product until the melt generator reaches the lower throughput limit of the pelletizing head and the pelletizing process can be started are cut by the use of initially one pelletizing head having a throughput capacity which is as low as possible. No further start-up product is incurred from the start onwards of the pelletizing process at the lower throughput limit of the said first pelletizing head. The melt volume flow is increased quantitatively for so long until the diverter valve can be switched to the second pelletizing head having the larger throughput capacity with no start-up product being incurred during this time period. Moreover, the throughput window is enlarged in total so that the number of unavoidable start-up procedures with start-up product arising therein is reduced since it is possible, on a ramping down of the melting performance below the lower throughput limit of the larger pelletizing head which may become necessary for various reasons, to switch back to the first pelletizing head. | 05-07-2009 |
