Abstract: Certain polyamide beads or granules are useful as a sustaining material for underground natural or artificial cracks of the earth's crust essentially employed for the extraction of hydrocarbons such as crude oil or natural gas; such polyamide beads have a spherical or ellipsoidal shape and have a surface free of concave portions, advantageously having a uniform shape, and having a mean diameter lower than or equal to 1.7 mm and a porosity lower than 0.1 ml/g, and are produced using a particular cutting device/extruder.

Abstract: A method and apparatus for underwater pelletizing and subsequent drying of crystallizing polymers to crystallize the polymer pellets with out subsequent heating is shown in FIG. 5. High velocity air or other inert gas is injected into the water and pellet slurry line (120) toward the dryer near the pelletizer exit (102) at a flow rate from about 100 to about 175 m3/hour, or more. Such high-speed air movement forms a vapor mist with the water and significantly increases th speed of the pellets into and out of the dryer such that the polymer pellets leave the dryer with sufficient latent heat to cause self-crystallization within the pellets. A valve mechanism in the slurry line (150) after the gas injection further regulates the pellet residence time and a vibrating conveyor after the dryer helps the pellets to achieve the desired level of crystallinity and to avoid agglomeration.
Abstract translation: 用于水下造粒和随后干燥结晶聚合物以在随后的加热之后使聚合物颗粒结晶的方法和装置如图1所示。 高速空气或其它惰性气体以约100至约175m 3 /小时或更高的流速向造粒机出口（102）附近的水和颗粒浆料管线（120）朝向干燥器注入。 这种高速空气运动与水形成蒸汽雾，并且显着地提高了颗粒进出干燥器的速度，使得聚合物颗粒离开干燥器具有足够的潜热以在颗粒内引起自结晶。 在气体注入之后的浆液管线（150）中的阀机构进一步调节颗粒停留时间，并且干燥器之后的振动输送机帮助颗粒达到期望的结晶度并避免结块。

Abstract: A melt processing plant is provided that includes a melt charger for charging a processing head, in particular a pelletizing head, with melt, in which a diverter valve for discharging the melt during a starting and/or retooling phase is associated to the melt charger upstream of the processing head. A splitter divides the discharged melt into melt portions with the melt channels of the splitter head having at least one step-like cross-sectional enlargement of their inflow portion, a cross-sectional shape different from the outlet cross-section of the discharge channel, and an open orifice region out of the splitter.

Abstract: A method and apparatus for the pelletization of plastics and/or polymers, in which 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 plurality of pelletizing heads have different throughput capacities and 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.

Abstract: A method and apparatus for underwater pelletizing and subsequent drying of polyethylene terephthalate (PET) polymers and other high temperature crystallizing polymeric materials to crystallize the polymer pellets without subsequent heating. High velocity air or other inert gas is injected into the water and pellet slurry line to the dryer near the pelletizer exit. Air is injected into the slurry line at a velocity of at least about 200 m3/hour. Such high-speed air movement forms a vapor mist with the water and significantly increases the speed of the pellets into and out of the dryer such that the PET polymer pellets leave the dryer at a temperature sufficient to self-initiate crystallization within the pellets.
