摘要： An apparatus for continuous pelletization and crystallization of a polymer includes a unit for forming a polymer pellet material and cooling the pellet material in a liquid cooling medium. An after-connected drying unit has an exit opening for exporting gas and a crystallizer for crystallizing the pellet material. The crystallizer communicates via a connection line with the pre-connected unit for separating the liquid cooling medium from the pellet material and drying the pellet material. The crystallizer communicates with an inert gas tank, whereby the pressure in the crystallizer can be increased relative to the pressure in the drying unit. A related process is also disclosed.

摘要： A process for continuously preparing a polyolefin composition made from or containing a polyolefin and carbon black in an extruder device. The process includes the steps of supplying polyolefin in form of a polyolefin powder and carbon black to a mixing device; alternatively, (a) measuring the flow rate of the polyolefin powder supplied to the mixing device or (b) measuring the flow rate of the polyolefin pellets prepared in the extruder device; adjusting the flow rate of the carbon black to the mixing device in response to the measured flow rate of the polyolefin powder or adjusting the flow rate of the polyolefin powder to the mixing device in response to the measured flow rate of the polyolefin pellets; melting and homogenizing the mixture within the extruder device; and pelletizing the polyolefin composition into the polyolefin pellets.

摘要： 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.

摘要： A cutter hub pin drive mechanism and a quick disconnect hub for a pelletizer and a pelletizer having a cutter hub pin drive mechanism are provided. The pelletizer has a cutter hub that includes a cutter hub holder which is engaged with the pelletizer shaft through a plurality of drive pins. The drive pins ride in drive pin channels formed by grooves cut into an inner surface of the cutter hub holder and aligned grooves formed in the outer surface of the forward end of the pelletizer shaft. By machining of grooves into the cutter hub holder and shaft to form channels that receive the drive pins, more precise engagement between the pelletizer shaft, cutter hub holder and drive pins is obtained, resulting in improved torque transmission from the shaft to the cutter hub. Also provided is a seal around the pelletizer shaft to prevent the egress of fines into the drive pin area which might otherwise interfere with the unobstructed movement of the cutter hub holder necessary to adjust blade position. Finally, a quick disconnect hub is provided by which the pelletizer shaft can be readily disconnected from the cutting assembly to facilitate the removal of agglomerated polymer in the cutting chamber.
