On XINDA Co-kneader, customer can realize:
1, the grafting process needs a precise tempeature control, while co-kneader can detect polymer tempeature
2, a liquid silane can be injected to melted polymer from the hollow pins 
3, good distribution and dispersion can be realized
4, very attracive for lab scale compounding for PE PP PS PET PBT ABS PC PEEK PSS
5, good dispersion and distribution effect

SKW-45: especially designed for more advanced compounding technology 


SJW XINDA Type Cascade Three Flights Co-Kneader Compound Extruder for Thermosets

Advantages of the XINDA Co-kneader

The Co-Kneader, a mild-shear rotating and reciprocating single-screw extruder, is designed for shear and temperature sensitive compounds. The flights on the screw are interrupted and interqct with three rows of stationarv kneadina pins located in the barrel wall. The interaction between the moving flights and the stationary pins provide dispersive and distributive mixing simultaneously. Axially opened split barrel guarantees ease of cleaning. Those splined, segmented screw elements and pins can be changed easily according to different processing techniques. In addition, some pins are hollow inside, thermocouples can be inserted to get the accu- rate temperature of the materials inside the barrels, so as to liquid additives injection. Different from other extruders, the kneading process is achieved radially and axially at the same time. All in all, Co-Kneader has outstanding kneading, mixing efficiency and high degree of self-wiping. It is the most suitable for compounding purposes.

Cascade two-stage co-kneader system for XLPE silane cross-linked cable Compounding: Co-kneader and discharging extruder build up two stage compounding system. 

 

Advantage of the compounding system:

--Lower energy input, lower melt temperatures
--Extremely homogeneous mixing, no shear spikes, equal treatment of polymer matrix
--High degree of self-wiping and have no dead spot
--Dispersive mixing without destroying delicate fllers
--High volumetric loadings of fllers 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
