Paramter table for SHJ (D) series twin screw extruder

The SHJ (D) 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 enables 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.
