CENMEN CO. self-developed Stone Paper series equipment, is capable of using high CaCO3 content (75-85%) and regular polymer raw material. By pelletizing and different forming method, the Stone Paper series equipment can provide Various types of paper-like final product. All kinds of auxiliary systems can be connected to the whole production line and fully configurated of automated operating system, which provides a One-Step method Stone Paper Project. The stone paper final product has variety types of paper application in soft and hard packing, poster, wallpaper, agenda, envelope, business card, writing paper, commercial printing paper, cultural paper, newsprint and etc.

Technical Process

Inorganic filler powder (70-80% content) + resin particles + auxiliary agents are compounded and granulated in high filling masterbatch, and directly through extrusion, calendering and casting and etc. technics to form sheet products. The products will be further processed (printing, cutting, adhesion and etc.) as stone paper series ultimately.

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.
