Preparation of Fatty and Oily Materials
Economical Preparation of
Greasy, Sticky and Moist Materials
Size Reduction of Fatty and
The size reduction and
sifting machines, used in the preparation steps of
fatty and oily materials, influence the product quality
in a decisive manner.
Depending on the fat
content, the required fineness and the type of desired
end product, different fine grinding systems are used.
For the economical pulverizing of greasy, sticky and
moist materials, the self-cleaning screen
Contra-Selector Mill, type PPS is used. Other
alternatives include the
Turbo Mill, type REF and the
Turbo Mill, type PP.
Fine Grinding of Fatty and
the feedstuff industry, parts of animals, which are not
suitable for human consumption, are further processed
into animal flour. Animal Flour is enriched with
valuable proteins and is used as additives for animal
feed or as fertilizers.
The high fat content leads
to screen blockages in common mills. PALLMANN
solves this problem with the
Contra-Selector Mill, type PPS.
A significant characteristic
Contra-Selector Mill, type PPS is the screen basket
counter-rotating to the impeller. Due to the high
revolutions of the screen basket, the screen remains
clear. Additional scrapers at the exterior of the
rotating screen basket minimize any material sticking to
the interior of the housing.
The advantage of this mills
is the continuous operation which minimize the operating
