Low-cost, high-efficiency, tapered, co-rotating twin-screw extruder

According to reports, Wu Hanmin, general manager of Jiangsu Zhoushan Dinghai Tongfa Plastics Co., Ltd., successfully developed a conical twin-screw extruder, which produced a four-fold increase in output per hour and a half reduction in power consumption per ton of material.

Comparing the performance of a conical twin-screw extruder and a Nanjing parallel co-rotating twin-screw extruder, the two machines use the same set of meters to create the same TPR material with a hardness of 75 degrees. The results showed that the output of a conical twin-screw extruder (screw diameter 65 mm) per hour was 485 kg, parallel co-rotating twin-screw extruder (screw diameter 60 mm) per hour output of 112.5 kg; material consumption per ton Electricity is 93 degrees and 222 degrees respectively.

According to Feng Lianxun, a professor at Beijing University of Chemical Technology who is known as China's first person for tapered counter-rotating twin-screws, this conical counter-rotating twin-screw extruder (referred to as conical machine) and parallel co-rotating twin-screw extruder (abbreviated as "Parallel machine" The advantage of a replacement product "fills the international gap." Chen Ziwei, deputy director of the Zhoushan North Polymer Processing Technology Research Institute, strongly recommended: "This product can apply for international invention patents."
