35mm Diameter Twin Screw Plastic Extruder
Usage: This machine line is not only good at Lab. Testing (formula & technical processing), but also for small production or small order for multispecies or multicolor.
HS CODE: 8477.2010
The machine line could be used for filler, color master batch, engineering granules and other plastic granules making.
This SHJ-35 Twin Screw Plastic Polymer Extruder is for wild usage, not only for Laboratory using, but also for production. like to say to make master batch, if you have small each quantity but with various of the colors, this machine line is your good choice. After finish the small order ty multi colors, you're only using little of pure transparient granules for screw cleaning, so the material wasting is also little.
Reference output capacity: (estimate) is around 10-80kgs/h ( for CaCO3 Powder added filler making.)
Output capacity: this model is for Lab. testing ( checking the formula or technical processing is workable or need to be adjusted.) different carrier (material) and its' specific gravity(proportion) and flow ability(fluidity) will changes the output capacity.
Sometimes, the customer will ask to equip a side feeder (single or two stages of side feeder) to add more axuliary raw material or agent, like to say CaCo3 powder, BaSO4 powder, short glass fibre and Etc..

Both screws and barrels are designed according to the principle of building block type. Let the machine line has excellent dispersion, mixing and compounding performance, controllable material duration of staying time in the barrels. In the meantime, this design also has good exhaust release performance, excellent interchangeability, self-cleaning, flexible module combination and other characteristics, to achieve a wide range of muti-function, multi-purpose and specific requirements of the specific unity。
New Mixing & Extrusion Elements (segments)
The SHJ series extruders have newly developed screw elements (segments) for good distributive and dispersive mixing and extrusion process. The special screw elements will be greatly conductive to the even shearing stress, even axial elongation rate, and low temperature distribution. All these factors will determinately lead to the final material or products’ quality.
The SHJ series extruders have unique features with a balanced shaft drive mechanism, a solution offering decisive advantages over the conventional gearing chain with a simple split of the driving torque. In the new solution the torque for the second screw is split again in half to drive two auxiliary shafts at levels above and below the second screw shank. Consequently the balanced gearing shafts have to bear the 25% torque of the overall. The extreme load ability connected with this type of gearing chain enable to work with the kind of torques required to achieve high output rates at lower screw speeds that will be decisive to the final performance of the mixing polymer.
Field of application:
SHJ series co-rotating twin screw extruders are mainly applied in polymer processing. To meet the increasingly demand from new materials and process, our company has been providing more new technologies and products accordingly.
