CIM series

Overview

CIM is developed for the mixing and pelletizing of polyethylene and contributes to development and optimization of plastics resin manufacturing process. It is a Continuous Intensive Mixer (CIM) designed primarily for processing polyolefin plastics to produce higher quality pellets at higher throughputs and is a Twin Screw Extruder with non-intermeshed, high-speed twin screws supported at both ends. A ROTARY SLOT BAR is installed downstream of the screw mixing zone to control product quality by adjusting resin pressure and is described as more effective against a short-pass and oxygen intrusion compared with the conventional gate valve style to achieve more uniform mixing of polymer. The mixer uses high-performance rotors in the screw rotors area to obtain optimum pellet quality, and the mixer design with support at both ends enables effective and high-speed processing of fine feed powder along with high throughput extrusion. The horizontally arranged discharge barrel with patented design ensures smoother transport of polymer from the mixer side wall to the gear pump without polymer stagnation, and a water-cooled, maintenance-free melt seal device without conventional gland packing is adopted so the molten resin itself prevents leakage through the ends of screw discharge. The mixer barrel end and the gear pump are rigidly connected on the horizontal plane to prevent polymer leakage at the horizontal plane and the connection flange, and thermal expansion of the mixer barrel is designed to move toward the upstream of the mixer side without affecting the underwater cut system. The CIM series is used for mixing and pelletizing polyethylene and for processing polyolefin plastics to produce higher quality pellets at higher throughputs. Listed applications include Polyolefin (large volume treatment) and Various compounds.
