Co-kneader is a 3-flight or 4-flight designed reciprocating single screw extruder specially designed for materials that sensitive to temperature and shearing. In the screw shaft, the modular-designed screw elements are with special design. The flights on the screw are interrupted and interact with 3 or 4 rows of stationary kneading pins located in the barrel wall. The interaction between the moving flights and the stationary pins provide dispersive and distributive mixing simultaneously. Meanwhile, the pins and the screw elements work together to keep the barrel self-wiping. Through proper screw design, it can keep the stable working pressure, which avoid the material inside the barrel to be degradable.
Main Structure Characteristic
The co-kneader liner and screw elements are modular assembled, which means that the kneading and conveying screw elements are assembled in the main shaft. The barrel can be opened quickly for cleaning and maintenance. According to different formula, the screw can be designed with the most suitable screw configuration to meet the processing demands.
Temprature Controlling System
Co-kneader's each barrel section is equipped with two sets of temperature sensors to obtain multiple temperature. Especially the melt polymer temperature sensor can get real-time and effective temperature of polymer inside each barrel section.
Advantages of Co-kneader
Ø Lower energy input, lower melt temperatures
Ø Extremely homogeneous mixing, no shear spikes, equal treatment of polymer matrix
Ø High degree of self-wiping and have no dead spot
Ø Dispersive mixing without destroying delicate fillers
Ø High volumetric loadings of fillers and additives
Ø Efficient blending of liquid components
Ø Broad application for compounding without changing hardware
Ø Axially opened split barrel guarantees ease of cleaning and fast maintenance
Ø Replacement parts, such as screws, barrel lining and pins can be changed individually
