High Efficiency Recycling Granulator Machine Single Screw Two Stage

High Efficiency Single Screw Recycling Granulation Production Line

Technical route for large-scale production of plastic recycling granulation:

High efficiency single screw extruder + melt single screw extruder mode:

The upper machine is a high-efficiency single-screw extruder, which realizes high-efficiency energy-saving plasticizing processing of plastic recycling material; a new filter is installed at the exit of the upper machine to filter the melt; vacuum is taken at the interface of the upper and lower machine, and the discharge is small. The molecular substance guarantees the melt quality; the lower machine is a single-screw melt extruder for melt extrusion, and the fine filtration of the melt is carried out at the outlet, and then the pellet is cut.

Advantages of the Two-stage machine

For the characteristics of plastic recycling, the two-section machine solution has advantages in melt filtration and exhaust.

More excellent melt filtration function, using "single + single" or "single + twin" two-stage machine mode, the upper machine filter is responsible for coarse filtration, and the lower machine filter is responsible for refined filtration.

The two-stage machine has a better exhaust function, and the connecting part of the upper and lower extruders is equipped with a vacuum device to remove a large amount of water vapor and volatile gases in the melt.

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.
