Malvern's Dr. Neil Lewis Honored

Malvern, UK -- Dr. E. Neil Lewis, Chief Technology Officer for materials characterization company Malvern® Instruments, has been honored by the University of Glamorgan in Wales with the award of an Honorary Doctorate of Science for his contribution to science and innovation. Now resident in the US, Neil Lewis obtained his basic training and science education at the University of Glamorgan more than 20 years ago. He was described at the ceremony as being “one of our most outstanding ambassadors in the world of science”.

Offering his congratulations, Paul Walker Managing Director of Malvern Instruments said: “The award of an Honorary Doctorate of Science is one of the most prestigious accolades that can be bestowed by a UK university. I know that I speak for the entire team at Malvern Instruments in congratulating Neil on gaining such tremendous recognition. We are extremely fortunate to have a great many high caliber scientists in the Malvern team and are delighted to see such public recognition of individual achievement.”

Following his graduation from the then Polytechnic of Wales in 1980, Neil Lewis went on to complete a PhD in the field of molecular spectroscopy. A series of posts at the National Institutes of Health in Bethesda Maryland, US followed, culminating in that of Senior Biophysical Researcher.

His activities involved the development of novel methods for chemical imaging of biological, medical and pharmaceutical materials, including groundbreaking work in the development of spectroscopic imaging microscopy. This utilized ideas from remote sensing, and also detector technology originally developed for military purposes by the US Government for night vision and missile guidance.

In 1998 Neil Lewis founded Spectral Dimensions Inc. which became the world leader in the manufacture of instrumentation and software for chemical imaging. In 2006 the company was acquired by Malvern Instruments and Neil joined the management team. Now as CTO he leads all of Malvern’s innovation and new product development initiatives.

R&D : Versatile Contained Filter Drying

Liverpool, England -- The PSL small scale contained filter dryer provides maximum efficiency and versatility in R&D kilo labs. This lab scale system has a 0.05 m2 filtration area with 15L liquid capacity and typical 2 to 8L wet cake capacity – perfect for multi product kilo facilities. Typical batch sizes of 1 to 5KG quantities with a compact system that can be easily moved round and receive slurry liquid from multiple reactors.

When developing compounds, containment requirements are always stringent, especially for NCEs (new chemical entities). Containment is achieved via a top mounted PSL ChargePoint, 100mm split valve, for vessel charging. A tilting mechanism, which is integrated into the frame, allows complete inversion of the vessel for contained powder discharge via the same spilt valve. The PSL ChargePoint achieves < 10 microgrammes/m3 containment, further ancillaries can be added to the standard valve to achieve < 1 microgramme/m3.

This small mobile filter dryer is ideal for API chemical kilo labs requiring a solution for filtration and drying of slurry from multiple reactors of various sizes, as is typical in R&D facilities. Compact design enables the unit to be easily moved by a single person, within standard walkway widths, to ensure this filter dryer can be easily moved between labs / rooms.

For added flexibility the base can be fitted with either filter cloth or sintered metallic mesh providing the flexibility required in a busy multi product kilo lab. Again, to maximize versatility, this filter dryer is designed with C22 alloy product contacts for flexibility primarily in solvent usage, the ChargePoint can also be in C22 alloy. 316L vessel and split valve options are available when solvents to be used are known to be less aggressive.

To ensure minimum slurry losses it is important to keep pipe lengths between reactor discharge and filter dryer to a minimum. This small scale unit has been designed with minimal height, enabling use in the tightest of areas.

This complete system, vessel and split valve, is pressure rated to 6 BarG. The vessel has integral spray balls for cleaning in place and a sight glass & light fitted to enable viewing of the process without breaching containment.

This kilo lab filter dryer has an ATEX approved control panel mounted on the trolley, plugs and sockets allow easy connection and disconnection for quick and simple set up in different locations.

This small scale contained filter dryer is simple to set up and operate, its versatility provides an invaluable addition to any kilo lab.

Belt Cleaners : New Razor-Back With Spray Bar

Allentown, PA -- Building on our goal to provide solutions to your conveyor belt problems, ASGCO Manufacturing introduces Razor-Back with Spray Bar, a secondary belt cleaner that uses a row of spray nozzles to spray a fine sharp stream of water at a 30° angle onto the conveyor belt where the carryback material is difficult to remove.

Water is applied to the belt in an overlapping spray pattern which places the particles into a fluid suspension, while moistening the belt. The blades of the Razor-Back with Spray Bar are then able to make consistent contact with the belt surface to remove nearly 98% or more of the coarse carry-back.

Applications
-High speed and tonnage above ground and underground mining conveyor systems running in the most aggressive environments
-Concentrator/Ball/Mill conveyors where water is available.
-As the secondary cleaner on a single direction conveyor where high levels of performance are demanded.
-Where the material to be removed is particularly sticky.

Contact ASGCO today for more information on Razor-Back with Spray Bar at 1-800-344-4000.

New Pulsonic Bin Activators

Belleville, NJ -- Pulsonic Bin Activators instantly clears bins, hoppers and other mass flow vessels of compacted solids. Removes disruptive materials from channels, ducts or recesses.

This bin activator incorporates a unique and patented system for the movement of flow-resistant material. The system acts positively on the material itself, rather than on the containing vessel. This causes no damage to the container, which can occur with vibration or severe shock techniques.

The system consists of air reservoirs and valve injectors, mounted on the vessel, which induce air blasts on the compacted material inside the vessel. An initial burst of compressed air acts directly on the particles, causing some motion.

Then, while the material is still in motion, a second burst is injected, evading the activity of the air in the container. Subsequent bursts are released, all within milliseconds of each other, each creating an amplified effect over the previous burst. The result is total activation and free flow of material in as little as one second.

The Pulsonic Bin Activator introduces multiple instantaneous sonic airbursts directly into compacted material to instantly restore flow, without severe shock and vibration methods that often damage your equipment.

Mr. Finch needs a silo for plastic pellets:

We currently take delivery of 50,000 lbs of small plastic pellets per month for injection molding. We require a storage silo and the ability to dispense about 1,250 lbs at a time.  (to post reply, click here)

Mr. Provencal needs help with mortar bagging:

After installing a new mortar bagging line we started experiencing a lot of troubles at our FIBC machine (uneven flow). The problem seems to come from a hopper located directly underneath a mixer.

Here are some dimensions:
Material handled: mortar (sand and masonry cement)
Batches ranging from 2000 kg to 4000 kg
Ribbon mixer outlet is 8" x 8" (unloading time is about a minute at 4000 kg)
Hopper dimensions: 80" long x 60" wide x 96" high
Walls angles: 60 and 68 deg.
Outlet size: 10" dia.

Sometimes material flows out of control sometimes it just sits there. What did I do wrong?  (to post reply, click here)
