Economical size reduction
of natural and synthetic rubber of any kind
Preparation of Rubber
Rubber is used in various
industrial branches for the production of many technical
products, comodity and consumer goods. The
following are the main applications:
Rubber is offered in various
shapes and sizes; i.e. bales, sheets, fibers, chips or
crumbs; however, bales being the most common.
For almost any type of
processing it is necessary that the bales are size
reduced into granules or powder. The result is a
shorter dissolving and mixing time as well as energy
saving kneading time. Due to the improved
flowability, the rubber material can be easily conveyed
and fed into an automatic weight dosing system, thus
achieving continuous manufacturing processes.
Granulation of Rubber
For the economical size
reduction of natural and synthetic rubber of any kind,
in form of bales, sheets or chips, vulcanized or
un-vulcanized, with or without textile reinforcement,
Ultra-Granulators™, series PS-C.
has designed special guillotine rotors, in open design,
without a traversing shaft and with a high momentum
flywheel. This design allows a low friction and
therefore temperature gentle size reduction. In
addition, a patented infeed chute with shuttle
flaps guarantees a guided material feeding and a dosed
Standard one, two or three
step size reduction systems can be offered. We
specialize in custom designed complete production lines.

For the production of
compounds for cable manufacturing, seals and other
elastic parts as well as for bitumen and asphalt
production, rubber powders in a wide variety of particle
sizes are required. PALLMANN offers various
grinding machines and systems in order to achieve the
necessary material qualities and end finenesses.
type PKM and
, type PP are used.
Pin Mills, type PPST
Cryogenic Grinding Systems
are used for special applications.
Granule shaped feed material
is fed into the mill by means of suitable metering
systems. A vacuum system, optimally suited for
this application, draws the material to be ground away
from the mill. Different types of screening
systems are used to achieve the desired powder
coarse material is reintroduced into the mill in a
closed loop, finished product is weighed into bags, in
accordance with the customers' requirements, filled into
containers or directly transported into the production
Standard systems for
installation on the production floor are available.
Individual set-up even in multy-level buildings is
possible, depending on the local conditions.

is a compact, fully automatic, and a proven
continuous system that converts light bulk density
thermoplastic waste, such as fibers,
into high quality, free flowing granules, which are
later used as valuable raw material in further processes.
The PALLMANN Agglomeration
process offers the unique advantage of material gentle
agglomeration with minimum heat and minimum
thermo-degradable damage therefore preventing any
yellowing of the agglomerate.; the material is heated up
with friction heat only and is agglomerated, within a
fraction of a second, right below the melting point.
Viscosity is insignificantly reduced.
