With less energy 'from melt to pellet'

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.

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.
