PROFILE CUTTER Z700
Foam rasp
ZEIM recycling cutter for expanded polystyrene (EPS)
The problem:
Generation of a milling chip suitable for reuse, which avoids clogging of the slotted screens in the block mould. The surface quality shows an acceptable milling pattern.
The solution:
The cutting edge geometries have been fundamentally changed compared to the conventional rasp toothing, i.e. with a small number of cutting edge rows (which nevertheless guarantees sufficient overlapping of the cutting edges), the desired milling grain size is produced with corresponding speed and feed parameters.
Condition:
In order to minimize downtimes (cleaning of the slotted screens) during the production of EPS with reusable milling chips, the use of a dust removal system is absolutely necessary,
– on the one hand to filter the dust generated in the raw granulate or by the shredding machine.
– on the other hand, in order to remove the fine chips which occur to approx. 10% during machining.
