From general-purpose plastics to super engineering plastics, blending is possible. Raw materials can be extracted in pellet or strip form.
This is a kneader equipped with two jackets and rolls that have spiral grooves on the surface, driven by separate motors. It achieves high dispersion through the shear action generated between the rolls, enabling the production of new functional materials. 【Features】 - The two rolls are driven by individual motors, allowing for the adjustment of mixing force by varying each roll's rotation speed. - The mixing force can be adjusted by changing the gap between the rolls. - It can process medium to high viscosity materials at temperatures ranging from 20 to 350°C. - The two rolls are separated into two jackets on the left and right, allowing for temperature control in a total of four zones. - The roll surfaces are easy to clean, accommodating raw materials that require frequent color changes.

basic information
【Structure】 - Materials are fed in from one end of the roll and are compressed and sheared, penetrating into the nip area of the roll. - The heat generated in the nip area and the heating of the jacket cause the resin to melt and wrap around the roll. 【Processing】 - Secondary materials can also be added in the latter half of the process. - Various types of rolls are available at both ends. By improving the penetration and kneading properties of the raw materials and reducing the number of grooves, it is possible to decrease the escape routes for the processed material and enhance dispersion. 【Extraction】 - By selecting a strip cutter or a pelletizer, the material can be extracted in strip or pellet form.
