Method of Operation
PALLMANN system Type PKM was developed for the
pulverization of various types of polyethylene
granules such as HDPE, MDPE and LLDPE and other
thermoplastics into rotomolding powders.
No only virgin, lentil or cylindrically shaped
granules can be successfully pulverized but also
recycled material from production waste.
feed material is placed into a storage bin and
fed to the Disc Mill by a vibratory feeder.
Pulverization of the feed material takes place
between the serrated grinding elements of a
stationary and a rotating disc.
The material is

powder silo. An all-metal separator, a filter, a
granules and powder conveying system as well as
laboratory systems can optionally be
