ZEIM recycling cutters for expanded polystyrene (EPS)



Task definition
:

Generation of shavings suitable for recycling that avoid the obstruction of the bar screens in the block form. Thereby the quality of finish shows an acceptable planed surface.



Solution:

The geometry of the cutting teeth has been completely modified compared with the traditional rasp toothing which means that the desired size of the cutting grain is achieved with a few number of tooth lines (that guarantee nevertheless a sufficient overlapping of the teeth) using adequate speed and advance parameters.



Conditions:

In order to minimise the downtimes (clearance of the bar screens) when producing EPS with recyclable shavings, the usage of a dust collecting device is absolutely necessary:

- On the one hand for filtering the dust generated in the raw granulation or by the crushing machine.

- On the other hand for removing the fine shavings which can account for up to 10 % of all shavings caused during processing.
