Characteristics of SLS Series Co-rotating Twin Scr

Because brick type design--modular design for working cells like screw element, kneading block, gear plate, is utilized for the screws, it is easy for co-rotating twin screw extruder to adjust the screw combinations and length-diameter ratio according to different properties of processing materia is and form ulacombinations variation, so as to realize the adaptability adjustment of screw structure and universality of one set to multiple material systems; furthermore, mutual engagement of two screws enables the screws to have good self-cleaning property , favorable for the frequent replacement and use of multiple material systems, as well as the reduction of down time of the machine and disposal cost of screws. The utilization of involute spline connection for working cells like screw's axe, screw element, kneading block , gear plate ensures good reliability and strength of connection, and has better adaptive capacity for higher working torque and larger service load. The utilization of modular design for barrel and cooperation of combinations adjustment with screw elements such as screw thread component, kneading block can realize modular configuration of different functional sections, including convey, pressure increase, shear, pugging, exhaust, etc , and can meet all kinds of demands, such as precise mixture , effective dispersion , even distribution , exhaust devolatilization, and extrusion increase for single machine. The barrel and screw elements can utilize a variety of materials , including nitridized steel like 38CrMoAlA , high speed tool steel like W6Mo5Cr4V2 , Bi-metal alloy like WC coating , etc based on the requirements of material system characteristics and variation of formula system. Based on the variation of different material processing techniques and functions, this serial set is divided into normal type Type A (n≤500r/min, T/A3<6), high speed type Type B (n≥600r/min, T/A3<6), high torque type Type C (n≤500r/min, T/A3>8) and high speed and high torque typeD (n≥600r/min, T/A3>8), which provides larger selective space for customers at all levels.
