the Polygrinder®, type PM, high quality powders
are gained for masterbatch production and
compounding. The optimum particle size of the
end powder guarantees a good mixture and
adhesion of the additives. The user can process
a wide spectrum of materials such as PE, PP, PA,
PC etc. at ambient temperature.
Method of Operation
vibratory feeder evenly feeds the granules into
the Polygrinder®, type PM. Pulverizing is
effected between the serrated grinding elements
of a rotating and a stationary grinding disc.
The downstream fan vacuums the powder from the
Disc Mill and conveys it, over a very short
distance, to the cyclone. The finished product
is discharged through a rotary air lock into a
bin. A filter (optional) cleans the discharged
air. The entire system is fully automatic and
controlled from a control cabinet. For operation
and cleaning purposes after material change, the
system has been designed in such a way, that the
mill and the piping are installed at a
comfortable working height.
