Single Screw Plastic Extruder Xinda Co Kneader Machine

Product Description

The Co-Kneader, a low-shear rotating and reciprocating single-screw extruder is designed for shear and temperature-sensitive compounds. The flights on the screw are interrupted and interact with three rows of stationary kneading pins located in the barrel wall. The interaction between the moving flights and the stationary pins provides dispersive and distributive mixing simultaneously.
Co-Kneader was first invented in 1945 by the famous Switzerland extruder company and has now grown into very mature and advanced compounding technology after years of practice in compounding industries. Co-Kneader is different from traditional single or twin screw extruders because of its unique mechanisms. The spiral of the kneading screw is detached three times at the circumference. In those gaps are the stationary kneading pins fixed inside the kneading case. While the screw is circumrotate, so too does the axis, moving reciprocally.

Product Description
Co-kneader (plastic compounding extruder) is one kind of continuous kneader and reciprocating single-screw extruder. Fillers or additives (Solid or liquid) can be evenly inducted into the melted polymers. Thus the end-pellets can achieve a high quality. Temperature probe immerses into the melts granting precise temperature control. Welcome to XInda to test our plastic compounding extruder.
Advantages of Co-kneader:
Lower energy input, lower melt temperatures.
Extremely homogenous mixing, no shear spikes, equal treatment of polymer matrix.
High degree of self-wiping and has no dead spot.
Dispersive mixing without destroying delicate fillers.
High volumetric loadings of fillers and additives.
Efficient blending of liquid components.
Broad application for compounding without changing hardware.
Axially opened split barrel guarantees ease of cleaning and fast maintenance.
Replacement parts, such as screws, barrel lining, and pins can be changed individually.
