Profile cutter Z700

Foam rasp

ZEIM recycling cutter for expanded polystyrene (EPS)

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.

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.
