molders need top quality powders with a controlled fineness, flow
ability and bulk density. Economical pulverization of
thermoplastics at ambient temperature is left to the specialist.
All powders are not equal. Different downstream processing
techniques require special adjustment to powder qualities with
specifically achieved particle form and sizes.
systems show the difference between fine grinding and
pulverization. The interaction between mill and screening
machine guarantees the necessary powder quality in accordance with
industry standards, in Germany under DIN 53492, and in America
under ASTM 1895. Powders with these characteristics
guarantee rotational molders the manufacturing of products with
highest dimensional accuracy and quality.
Polygrinder®-Systems guarantee adherence to quality parameters
has developed standard
Polygrinder, type PKM which have
taken a leading position in the market. The leading custom
grinders produce indispensable powder qualities for the market
with our mills, from which products such as rainwater tanks,
construction barriers, oil tanks, gas tanks, and technical parts
are manufactured. Due to the favorable price-efficiency
ratio, the investment in a pulverization system realizes itself
within a few months.
The fully automatic systems pulverize
up to 10,000 tons per year, per system in a three-shift operation
in large rotational molding companies and custom grinding plants.
The personnel requirement remains at a minimum and thanks to the
extremely long life of the grinding elements, these machines can
be operated around the clock.
