Bollegraaf Recycling Machinery
of The Netherlands has developed a
new product to optimise new or ex-
isting recovered paper sorting sys-
tems. By using the Drumfeeder,
which consists of a storage bunker
with a belt feeder and drum, it is
possible to feed sorting systems,
balers and shredders at a constant
flow and thereby to help maximise
output material quality, explains
the Dutch manufacturer.
The Drumfeeder also has the
added benefit of storing large quan-
tities of material, thus allowing the
operator more time for other duties.
Depending on its size and the mater-
ial in question, the bunker can be
loaded several times per hour.
The system is of solid construc-
tion and is well suited to use in in-
dustrial environments, according to
Bollegraaf. It can also be installed
within existing operations, the com-
pany adds.
The Drumfeeder’s bunker belt is
made from steel with a smooth top
surface and is driven by two heavy
chains. The drum is powered by an
electric motor with gearbox, the
speed of which can be adjusted by a
frequency regulator. The revolutions
of the drum determine the feeding
capacity of the material to be sorted.
For opening or breaking down
material, the drum is provided with
separating beams.

Thermo Electron Corporation has
introduced the ARL 9900, an analyt-
ical system harnessing both X-ray
fluorescence (XRF) and X-ray dif-
fraction (XRD) technologies. The
new device has been developed to
meet increasing demand within the
metals industry for high precision
and reliability of chemical analysis.
According to Thermo, combining
XRF with a unique patented XRD
system permits quantitative phase
analysis of related compounds or
minerals, in addition to rapid and
precise analysis of up to 83 elements
from ppm levels to 100% in various
solid samples. Using this technolo-
gy, a solid sample is analysed with
Niton is claiming a breakthrough
in trace element analysis in alloys
with its XLt 800 SY alloy analyser,
which features improved targeted
X-ray tube excitation. Combined
with a newly-developed Super PiN
detector, the device is said to yield
dramatic improvements in mini-
mum detectable limits for chromi-
um, copper, nickel, molybdenum and
other trace elements in alloy materi-
al. These new capabilities enable the
use of portable X-ray fluorescence
(XRF) as part of the flow accelerated
corrosion (FAC) inspection protocol.
The new XLt 898 SY is claimed to
offer exceptional repeatability and
accuracy for chromium in carbon
steels in the range 0.02-0.1%. The
device weighs approximately 3.0 lb
(1.4 kg) and operates off a battery for
a minimum of 8 hours. Little or no
sample preparation is required, data
are instantaneously available, and
operation of the device requires no
technical expertise.

one analytical program, and a com-
prehensive report of both chemical
and phase analysis is generated for
process and quality control in indus-
trial applications.
The ARL 9900 can be equipped
with a SmartGonio goniometer for
simple, cost-effective configurations
or with the universal version for
more advanced, flexible analysis.
