The planetary screw revolves and rotates on its axis, in order to employ various resinThe extruder has the advantages of multi-application, can be used for sheeting, filming instead by using banbury mixer/open mill mixer, and used for high capacity pelletizing, its capacity could reach to 2000kg/h. In special, because the extruder supplies the rolling and extrusion through space of the inter-engagement, it may plasticize the resin at a low temperature.Through the inter-meshing action of the toothed planetary roller system just one single revolution of the main spindle suffices to roll out the plastic melt as many as 1,100 times, ensuring optimum plastification, homogenization and dispersion. The "PRE" is a low-temperature forming extruder which may produce without any change of properties owing to its low-temperature forming and homogenizing.Combined rolling and extruding action: through the inter-meshing action of the toothed planetary roller system just one single revolution of the main spindle suffices to roll out the plastic melt as many as 1,100 times, ensuring optimum plastification, homogenization and dispersion.Compared with other extruder designs, this system increases the contact surface of the melt by up to five times.Low-cost formulation: the optimum heat-exchanging effect created by the large contact surfaces of the planetary roller system in conjunction with short residence time of the melt helps to achieve a considerable reduction in formulation costs. Costly stabilizers and lubricants are reduced to a minimum.Self-cleaning feature: since all toothed components of the machine constantly inter-mesh, no residual material is left in the machine when changing over from one formulation to another. The system is change-over from one color to another, results in no more than 5kg of scrap.
