Pneumatic
Conveying for Noodle Producer
 Belleville,
NJ -- When Brian Miller, Plant Engineer for Mrs. Miller’s
Homemade Noodles Ltd., which produces 40,000 pounds of
noodles per week, switched from handling 50-pound bags of
flour to handling 2000-pound bulk bags, he knew he would
need to integrate a new pneumatic conveying system into his
process. The former conveyor — an older pressure-based
system which transported the flour from a hopper through a
volumetric feeder and finally to a mixer — would no longer
satisfy the company’s needs.
Mrs. Miller’s Homemade Noodles
Ltd., located in the middle of an Amish community in
Fredericksburg, Ohio, is a family-owned and operated
business dedicated to producing preservative-free,
homemade-quality products with the best ingredients, for
over 30 years.
Miller’s goal was to implement a
pneumatic conveying system that would efficiently convey 20
tons of very fine flour per week, eliminating the need for
manual filling.
"The flour we use is like bakers
flour and it is difficult to convey," says Miller. "It
sticks to a lot of surfaces and if you have leaks in your
system you get a lot of dust."
After some research, Miller
found he could achieve this goal with a pneumatic conveying
system from Vac-U-Max, a pioneer in vacuum solutions since
1946, and one of the few suppliers who routinely designs and
builds custom and semi-custom pneumatic conveying systems
and support equipment for conveying, batching and weighing
dry materials.
While fine powders may pose
conveying issues for some conveyor manufacturers, because
Vac-U-Max has tested thousands of difficult to convey
materials and is an expert in material characteristics, they
are fully equipped to meet customer demands. One way that
Vac-U-Max handles problems with fine powders is by applying
a high polish finish to the pneumatic conveyor systems’
interior and exterior, reducing the amount of powder
sticking to the system.
Since the inherent nature of
pneumatic conveyor systems prevent loose powder from
becoming airborne, it makes for a cleaner and safer
environment all around. Miller says, "the system is
completely enclosed. It’s been very good that way. No mess."
Although the system has reduced
some housekeeping time, Miller, who is committed to
continually evaluating and improving safety in their plant,
says, "the bulk of the gain is safety and efficiency.
The new system is safer because it accommodates the super
sacks better, and feeds the product directly from bags
without manual labor," he explains. "Before, our guys were
climbing up to a big hopper and would fill it by hand
sometimes. Just more dangerous."
Overall, Miller says, "the
Vac-U-Max system runs more efficiently than the other system
did, is quieter, and doesn’t take as much space because we
could eliminate the big hopper, and it is safer."

Matec “Pondless” Washing System
 Boca
Raton, FL -- Matec In America has recently introduced
revolutionary dewatering technology to North America. The
Matec line of water treatment equipment has enjoyed great
success world-wide with hundreds of installations, for the
express purpose of cleaning up and recovering up to 90% of
the washwater, and eliminating settlement ponds at quarries,
mines and other aggregate facilities.
Washwater and settlement pond
problems facing today’s aggregate producers and mines
include issues with conservation, zoning, environment, EPA
flyovers and fines, water restrictions, high pumping costs,
tying up real estate and the high cost of maintaining the
ponds, including excavator and drag-line issues for dig-out.
Overcoming these problems
lies within the heart of the Matec System, the only HPT High
Pressure Filter Press and decanter-style Clarifier. Besides
having a small footprint, the system has dramatically lower
maintenance costs than any other methods of water recovery
or dewatering, and essentially has no moving parts.
The end result is a super-dry
dirt cake that is so dense and so dry (80%+ solids), it can
easily be stockpiled and sold as a desirable product for
landfill cover or other purposes; the dirty water is
cleaned, and as much as 90% of the water is recycled back
into the process.
The most significant benefits
of going pondless are substantial cost savings and quick ROI
as a result of freedom from environmental problems, no
associated costs of settlement ponds and their upkeep,
operating costs for energy, manpower, wear and tear on
earthmoving equipment, and freed-up real estate.

Maguire : High-throughput MGF
Gravimetric Feeder
 Tamworth,
UK -- An advanced model of the Maguire® MGF gravimetric
feeder provides more than double the throughput of the
original system but has the same compact size and offers the
same substantial price advantage over competing gravimetric
units, it was announced today by Maguire Europe. The company
will introduce the new feeder to the world market at K 2010
(Hall 10, Stand A 26).
Used
for feeding colorants and additives into plastics processing
machines, the new MGF system is driven by a motor that is
smaller than the one in the earlier feeder but delivers
material at rates of up to 36 kg (80 lb.) per hour, compared
with the previous top throughput of 13.6 kg (30 lb.). Yet
the feeder still costs the same as conventional volumetric
feeders and is nearly 40% less expensive than competing
gravimetric models.
Also
new is a networking option that has long been deployed
successfully by many users of Maguire® Weigh Scale Blenders.
Controllers for the MGF feeders can now be networked with
Maguire’s Gravimetric Gateway™. or G2™, software. This
program provides exhaustive material-usage reports, displays
alarms from anywhere in the network, gives access to
specific machines from remote locations, and monitors
inventory levels.
“The
increased throughput of the MGF feeder increases the
applicability of this system without any compromise in
compactness and affordability,” said Paul Edmondson, general
manager of Maguire Europe. “At the same time, this advanced
system enables more companies to obtain the advantages of
gravimetric feeders over the volumetric devices that
currently dominate the industry. Gravimetric feeders are
simply less complicated, easier to use, and more accurate.”
The
accuracy of the MGF feeder stems from the use of load cells
to monitor the loss in weight of colorant in a hopper
(mounted on the load cell) as the material is fed into the
processing machine by an auger. Software in the feeder
control scans data on color consumption every half-second
and automatically adjusts dispensing when a predetermined
amount of accumulated error is detected.
“By
responding exclusively to accumulated error over a given
period of time, Maguire’s proprietary software focuses on
real changes in throughput, not transitory or anomalous
changes caused by vibration, clumping, or surges,” Edmondson
said. “Thus the system provides real-time control and
absolutely smooth metering consistency.”
A
video about the MGF feeder shows how the equipment works and
presents its advantages over competing systems.

"Tea Time" for Vortex Valves’
Wye Line Diverter
 Salina,
KS -- Tea and coffee merchant, Taylors of Harrogate,
recently recruited Vortex Valves to assist in improving
their tea transfer system at its North Yorkshire plant.
In order to reduce costs and energy consumption, four Vortex
Wye Line Diverters were installed in the system, thus
enabling a reduction in pipework and the number of vacuum
pumps required for each line.
Staff at the Vortex Darlington
office were contacted by Taylors, who had identified the Wye
Line Diverter from the Vortex website as a potential
alternative for their tea transfer system. Taylors
were visited by Vortex representatives just 90 minutes after
this initial enquiry.
At the plant, the blended tea was
transferred to each packaging machine by a dedicated vacuum
system. The project was to combine these two systems into
one, reducing the number of vacuum pumps and quantity of
pipe work whilst not affecting the quality, taste or
structure of the tea in any way.
Following the decision that Two
Way Wye Line Diverters offered the best solution, Taylors
were able to test a set of four diverters on a trial basis
for several weeks. At the end of this period, Taylors
confirmed that the diverters were performing to expectation
and placed a further order for eight more Wye Line
Diverters.
Taylors added “Dry leaf tea is a
very abrasive material and we certainly valued the trial
service that Vortex provided, so that we could evaluate them
in use with our product. They also fitted the valves with
abrasion resistant liners to help us get around the
potential problem.”
By using Two Way Wye Line
Diverters in pairing together new manufacturing and
packaging lines, Taylors have already reduced power
consumption and noise in the production hall by eliminating
three 4.3kW electric motors.
Due to Taylors continuing growth
in the UK tea market plans are in place to install more
systems over the next two to three years, using Vortex
valves.

Mr. Livni is
looking for a special slewing bearing
We are looking
for reliable producer for special slewing bearing as
follows:
The bearing has
been working for about 40 years and it has been completely
worn down. The bearing sits on a UPN profile and it's
connected to the profile with M14 bolts (attached please
find a schematic drawing). On the top of the bearing there
is a 25 ton load. The velocity of the bearing's rotation is
0.033 RPM.
Each bearing's
ring is made from two halves connected with bolts between
then (attached you'll find the bearing's picture), otherwise
it would be impossible to assemble the bearing (its
assembled on a continuous pillar, assembled picture is also
attached).
Please send us a
quotation for the slewing bearing according to the above
mentioned specifications. If any additional information is
still required, please don't hesitate to contact us.
Please also
mention the material you intend to use, hardening and
surface treatment (if required) and delivery time which is
critical in our case.

Addressing Common Airlock Issues
Guest article by Cem Brinckley
Rotary Airlock, LLC
Though
seemingly a small item in the overall picture, an
airlock’s failure could result in something as subtle
(but still costly) as a loss of efficiency – or the
complete shutdown of a production line. It is important,
then, to make sure the airlocks are properly functioning
and maintained to bring maximum efficiency and run-time
to the manufacturing process... (Click
