High Automation Plastic Compounding Machine With Water Strand Pelletizing Mode

Filling modification--PP, PA/talcum powder, CaCO3, Mica barium sulfate, etc compounding extrusion pelletizing production

Company's twin screw production equipment used in compounding modified pelletizing has the advantages of high output, high automation and large-scale centralized control.

1. High output. Twin screw extruder adopts high torque high rotation speed gear box, matched with novel wear-resistance barrel and screw, torque grade 9~11T/A3, the maximum torque grade can reach as high as 15 T/A3.

2. High degree of automation of complete set of production line. Automation includes material storage and conveying, weighing mixing and metering feeding, compounding and pelletizing, automatic packing, finishing the whole process from material to product granule.

3. Multiple equipment large-scale and integrated production. The automatic centralized control system is adopted to share capital construction and environmental protection facilities, effectively reduce various production and operation costs (such as raw material procurement and transportation cost, labor cost, equipment procurement, capital construction cost, etc.)

Process description:

The polymer (PP, PA, BAS, etc.) is used as the base resin, and the inorganic filler (calcium carbonate, talcum powder, etc.) is added and is mixed with the resin uniformly, to reach the aim of reducing material cost, increasing product rigidity, improving the heat resistance temperature of the product, reducing thermal shrinkage, etc.

The plastic particles, additives and powders were fed into the twin screw extruder in the form of multiple feeding, high precision of proportioning, avoiding classification and bridge. The simple formulation can also adopt premix process mixed evenly by high speed mixer, and then fed into twin screw extruder.

The assembly structure for barrel and screw can be adjusted according to the requirements of compounding and dispersion, side feeding, exhaust and vacuum, etc, to meet their different process requirements.

The common pelletizing mode is water strand pelletizing.

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.
