Rigid PVC Compounding Double Screw Extruder Machine Large Capacity

Configuration & Features

Up-stage is the twin screw extruder, compounding and extruding the material inside, then free falling into down-stage larger size single screw extruder for compression, low speed, cooling down extruding pelletizing, the two-stage installed to vertical “T” type.

Twin screw is for conveying, high efficiency compounding and shearing dispersing, no counter pressure because of no die head, which avoid temperature peak and ensure high output. Single screw is for cooling and high pressure, low speed extruding and pelletizing.

Excellent compounding effectiveness and high output, because of two stage design.

Application:

Heat sensitivity polymers material processing, such as PVC cable compounds, transparent material, PE cross linking compound, PE shielded cable and foam material for shoes etc.

Technical Data of SDJ Series Two-stage (Twin screw/Single screw) Extruder Unit

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.
