Tianhua Combines 60 years of expertise of manufacturing co - rotating twin - screw extruder and makes special equipment. The twin - screw extruder table, cold brand granulation equipment and etc. Through continuous optimization and development, we have developed series production line which reached 15 - 1500 kg/h. The performance of the equipment keeps up with the advanced levels of the same products abroad. Compare with the more applied double roller open mill, the openable barrel twin - screw extruder has superior compounding performance, uniform heat transfer, closed continuous production, steady quality, self - clean function and narrow residence time distribution. It does not need clean the equipment and replace the material with different color. So this kind of equipment adapts to a variety of materials to extrude steadily and continuously. In addition the equipment can accompanied with polymerization and chemical combination which is beneficial new product developer.
