conical co-rotating twin screw extrusion, which have both advantage of big extrusion pressure of conical counter-rotating twin screw extruder and good plasticization of parallel co-rotating twin screw extruder, in addition, it has stable extrusion pressure of Single Screw Extruder, saving energy obviously, and will become the best equipment to make aluminum composite panel.
At present, the aluminum composite panel is usually extruded by single screw, with main motor power 160-250KW, output around 600-700KG/hour, however, its host engine consume power is more than 300 kwh per ton. Compared to single screw extruder, conical co-rotating twin-screw extruder has obvious advantage of:
I Saving energy: the SJSZ-85 extruder is able to save 150 kwh per ton, 2000-3000 kwh in total every day, so could return the investment soon;
II High output: single screw extruder production for 1200-1300 plates per day, the output of SJSZ- 85 twin screw extruder can reach to two or four times of it per day;
III Good plasticzation : it is able to process not only for A grade, but also for C grade recycled plastic, so it can use higher proportion of recycled plastic or filler than single screw extruder, saving much cost of raw material. It is suitable for high fire retardant ACP production;
IV The machine uses large rotating bearing and large taper screw, so that could bear high torque extruder.
Zhoushan Tongfa Machinery Co.,Ltd.
The company has undertaken many national, provincial and municipal scientific research projects, such as "National Torch Plan", "National Key New Product", "Zhejiang Energy-saving Technology, Product Promotion Oriented Catalog Product (batch six) ". It has won the honorary titles, such as [the Third prize of china light industry federation Science and Technology invention award"`.[National contract abiding and Trustworthy Enterprise" .[the Third prize of Zhejiang province Science and technology award".[Zhejiang standard innovation-oriented Enterprise".[pioneer enterprise for innovation and development ".
National invention patent product - "conical co-rotating twin-screw extruder" (patent No.: 200510118915.3) is a product successfully researched and developed by our company, which has won the national invention patent and has been given the honor of "Zhejiang Famous Brand". The product has passed through the provincial-level product identification in 2007: with the characteristics of high mixing, low shearing force, high pressure and low temperature for extrusion, and good plasticizing properties. Compared to "conical anisotropy twin-screw extruder" and "parallel co-rotating twin-screw extruder" , its production is about twice higher and its power (power consumption) is 30% to 50% lower by significant energy-saving effect. The main performance parameters of conical co-rotating twin-screw extruder have reached the international advanced level and this product is regarded as the leading product in domestic market.
In 2012, the product was listed in the national development and reform commission energy conservation technology popularization directory (group 5).
