Reactive/Devolatilization Twin screw extruder

It is required dispersing and mixing, shearing and kneading, heat transfer evaporation and devolatilization in high viscosity melt, liquid reactive or devolatilization process.

Equipped with a high-torque gearbox and high-powered motor to solve the torque problem in high-viscosity material processing; with a special screw structure design, the twin screws mesh with each other to provide strong mixing while pushing materials including high-viscosity materials move forward; good self-cleaning effect, prevent dead zone and accumulation of scale and improve heat transfer efficiency. Efficient distribution mixing and interface update effects.

A variety of liquid additive feed ports and vacuum openings can be provided according to the process requirements and a high efficiency vacuum system can be connected.

It is used to mix the polymer with additives such as crosslinking agent or foaming agent, and to remove the internal volatiles later. The special screw and barrel L/D greatly increases the working volume, which can greatly extend the residence time and working capacity of the machining process. The core of the screw shaft can be heated and cooled to have a larger heat exchange area.

The core extruder equipment includes parallel twin screw compounding extruder, reciprocating

compounding kneader, double rotor compounding extruder, SCP high viscosity self cleaning

reactor and large capacity devolatilizer, etc.

At the same time, based on the above main extruder, the design and manufacture of a

complete set of compounding pelletizing production line equipment and compounding

extrusion forming production line equipment can be realized. It is mainly used in the fields

of engineering plastics, modified plastics, wire and cable materials, rubber, packaging,

building medical chemical industry, chemical fiber textile, household appliance and other

industries (see the application case for details).

The existing factory area of the company is 46500 m2 (of which the parent company is

38000m2, and the subsidiary (Nanjing Cenmen) is 8500m2), The core parts and system

of the extruder are designed and manufactured by the company, such as barrel, screw,

gear box, etc. The company has advanced NC machining center, NC screw grinder,

CNC machine tool and other machining equipment. Equipped with Swiss imported

three-coordinate detector and Japanese imported spectral detector and other

advanced inspection and testing equipment. There are complete quality control means

and system from processing to testing, which fully ensure the stability and reliability of

product quality.

The extruders produced by Cenmen company are exported to nearly 40 countries, such as

Germany, Russia, belarus, Japan, Korea, Israel, Ukraine, magiddon, Iran, Thailand, Indonesia,

Brazil, India, Mexico, South Africa, etc.
