able but the inner rotating disc is not,
the outer and inner discs can swing
away from the unit on cantilevered
arms, providing full access to both
sides of both discs and the mill housing
for rapid cleaning and sanitizing.
Setting the infinitely variable rotor
speed between several hundred and
5,400 rpm provides the flexibility to
use the machine for coarse grinding
and de-agglomerating as well as
for fine grinding down to 400 mesh.
Constructed of 316 stainless steel,
the unit features a sanitary butterfly
valve on the air intake, sanitary fittings
at the material intake and discharge
and a wash-down-duty motor. -

large volumes of materials
The Delumper Triple-LP Crusher
(photo) is engineered to reduce massive
quantities of plastics, minerals,
chemicals, lumps, chunks and agglomerates
to controlled output sizes.
Designed with a unique ability to
handle sticky, wet, moist substances
as well as dry caked solids, the TripleLP
Crusher features a heavily constructed
body and low-friction cutter
design with three parallel shafts of individual
replaceable cutters mounted
in a staggered pattern around the
shaft diameter. Each shaft has heavy
outboard bearings and a shaft seal
to protect the bearings and retain the
product in the cutting area. The TripleLP
is available in two series: LP standard
crushers are designed for high
capacity on light- to medium-weight
materials, and HD units are designed
for continuous, high-load operation
with heavy materials at a rate of up to
38,000 ft3/h (1,080 m3/h). - Franklin

A robust granulator for efficient
PET bottle recycling
This company has recently extended
its range of Panther recycling granulators,
by adding a granulator that
has been specially designed for recycling
reusable materials from polyethylene
terephthalate (PET) bottles
(photo). Individual PET bottles are
continuously fed into the cutting
chamber, by means of a conveyor
belt. Massive, angled rotor knives

work with a very close cutting gap
against opposing slanted counter
knives and cut the bottles into flakes.
The lower part of the housing is fitted
with a large screen, which holds the
PET flakes in the cutting chamber
until they are discharged through the
screen holes. The mesh size can be
selected, which determines the size
of the flakes and throughput rate of
the granulator. Throughput rates of
up to 3.5 ton/h are possible with a
flake size of approximately 14 mm
and the appropriate machine size.

A laboratory mill with
a high-speed rotor
The Variable Speed Rotor Mill Pulverisette
14 premium line (photo) offers
impact, shearing and cutting comminution
in one instrument. The machine
has a higher performance, better
cooling and is significantly quieter
than comparable instruments, says
the manufacturer. Its powerful motor
is ideal for the particularly fast comminution
of soft to medium-hard, brittle
as well as fibrous materials and temperature-sensitive
samples with an
extremely fast sample throughput of
up to 15 L/h and more, depending on
the material and parameter settings.
A high-speed motor with ceramic
bearings ensures a particularly high
impact and rotor speed up to 22,000
rpm. Particles with a fineness down to
d50 < 40 μm are achieved. - Fritsch
GmbH, Idar-Oberstein, Germany

A universal milling platform
with five heads
The FreDrive multifunctional milling
platform can accommodate up to five
different grinding heads, providing
primary crushing, de-agglomeration,
granulation, fine grinding or control
screening. Intended for use in the
chemical, pharmaceutical and food
industries, the FreDrive can process
sticky, hard or crystalline powders
with varying product characteristics.
The FreDrive can be mounted on a
mobile lifter, and users have the option
to dock the mill anywhere in the
production area to bring the device
to a desired height. - Frewitt SA,
