With less energy 'from melt to pellet'

Good news for virgin polymer producers
Are you interested in saving energy with your KE single-screw extruders? Then you should look to KraussMaffei for energy-optimized screw concepts. These are integrated into a large-scale system for the production of polyethylene (LDPE) and ethylene vinyl acetate (EVA) and are suitable for both retrofitting and new systems. It's a straightforward concept: simply replace the screw and save between 25% and 35% energy.
In the production of polyolefins, both reactor technology and process control have evolved in recent years. For example, a homogenizing screw with maillifer 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.
The new screw geometry enables 35% energy savings when processing LDPE and EVA.
In addition, the optimization carried out at KraussMaffei on the screw geometry saves up to 35% energy.
"We were able to improve the screw profile of our large single-screw extruders in a way that results in up to 10% higher specific throughput. In turn, this ensures energy savings", explained André Klingeberg, head of sales and global application & product owner melt to pellet.
