SK96 Twin Screw Extruder

Overview of SK96 Twin Screw Extruder

SK96 twin screw extruder can be used in single filling masterbatch, engineering plastics, polyolefin powder granulation, and other industries. This extrusion screw for sale can also be used in reactive extrusion, devolatilization, and other operations.

Nanjing KY Chemical Machinery Co., Ltd. has the ability to design, manufacture and develop special operations such as reaction extrusion, dehydration, and dehydration, such as PPC devolatilization, ultra-high molecular weight polyethylene spinning, PA reactive extrusion, fluoroplastics, and other products.

Advantages of SK96 twin screw extruder

  1. In order to meet the requirement of reaction time in the reactive extrusion process,  KY has a deep groove screw design with a groove depth ratio of 1.8. It greatly improves the residence time of materials in the screw.

  2. At the same time, in order to prolong the residence time, the equipment with a large aspect ratio is adopted; the ratio of length to diameter can reach L/D=68; even longer, Nanjing KY Chemical Machinery Co., Ltd., as one of the professional twin screw extruder manufacturers in China, has rich experience in the equipment with large aspect ratio.

  3. In the process of devolatilization and extrusion, a special design of exhaust chamber, exhaust block, and so on, and the accurate calculation of exhaust gas volume were adopted.

  4. The water content of some raw materials can reach 20% or even higher, which requires that the water content in the material be reduced by the upper screw extruder. In order to meet the requirements of this kind of dewatering operation, Keya can extrude the water content in the raw materials in the feeding area through a specially designed drainage cylinder, screw, and vacuum to prevent the remaining water from being pumped out in the mixing and extrusion area.
