With less energy "from melt to pellet"

Good news for virgin polymer producers
You are interested in saving energy with your KE single-screw extruders? For this purpose, KraussMaffei offers energy-optimized screw concepts. These are integrated into a large-scale chemical plant and are suitable for retrofitting as well as for new plants. An uncomplicated concept: Simply replace the screw and save between 25 and 35 percent energy.
In the production of polyolefins, both reactor technology and process control have evolved in recent years. For example, a homogenizing screw with maillefer shear parts is no longer required to minimize unwanted gels or fisheyes.
Meanwhile, a typical discharge screw is sufficient to homogenize the melt exiting the reactor and transport it to the pelletizing unit. As a result, less shear energy is required and therefore less energy needs to be expended, leading to energy savings.


In addition, the optimization carried out at KraussMaffei on the screw geometry saves up to 35 percent energy. "We were able to improve the screw profile of our large single-screw extruders in a way that results in up to 10 percent higher specific throughput. In turn, this ensures energy savings", explains André Klingeberg, Head of Sales and Global Application & Product Owner Melt to Pellet. Are you interested?
