Erie, PA - March 2003 - Eriez has released its first in a series of "Ask Orange" Reference Guides. How to Choose & Use Magnetic Separators is a new 16-page "How-to" manual covering magnetic materials, differences in dry, moist and liquid process applications and a complete overview of magnetic separation equipment.

It details the power of rare earth magnets, proper equipment selection by process, time saving options and helpful hints. The "hints" provide hyperlinks to online calculators, diagrams and many free tools to simplify equipment selection. The Ask Orange Series of How-to manuals provide solutions to process problems.

In addition to this series of quick reading reference guides, the "Ask Orange" collection will include more than 230 process solutions located on the company's web site. This material will be of interest to individuals responsible for specifying and purchasing magnetic separation equipment.

The new "Professor" icon has been developed to help customers identify Ask Orange material in printed trade publications, company literature and on its web site. The Ask Orange concept and related images are a tribute to the company's founder, Orange F. Merwin, and his innovative ideas using magnets to remove metal contamination from various process flows.

Eriez, recognized as "world authority in advanced technology for magnetic, vibratory and metal detection applications," designs, develops, manufactures and markets advanced technology equipment for magnetic separation, metal detection and materials feeding, screening, conveying and controlling applications. Eriez manufactures and markets these products through ten international facilities located on five continents.

Whitewater, WI -- For metering plastic pellets, grains, and other free flowing materials into rail cars, AccuRate's Multicor Solids Flowmeter offers precise measuring accuracies as well as time and cost savings. An example of the benefits provided by the Multicor is further described through the metering of plastic pellets.

After going through the extrusion and screening process, the finished pellets are transferred through a tube inlet into the Multicor. The Multicor totalizes the weight of the pellets and moves the materials through a vented air lock into a pneumatic conveyor line, which delivers the pellets into a silo. By totalizing all the plastic pellets through the Multicor, the system automatically dispenses the appropriate amount from the silo needed to fill one rail car. After the rail car is filled with materials from the silo it is taken to a rail scale to be weighed.

The key benefit of using the Multicor in this process is clearly illustrated during the weighing of the rail car at the rail scale. For processors that do not use a Multicor to totalize the amount of material going into the silo, they run the risk of having their rail cars either under weight or over weight after being weighed at the rail scale. This forces them to return to the loading station to either remove material or add material to the rail car. By having a Multicor in place prior to loading materials into the silo the chances for under or over weighment are significantly reduced. This, in effect, saves processors the time and cost of continually going back and forth between the loading silos and the rail scales.

Other features of the Multicor include:

• Measures at high capacity, free flowing materials
• Flow rates up to 10,000 cubic feet per hour
• ± .5% accuracy available when metering over 2 tons per hour
• Can handle material temperatures up to 266° F

WBF Users Group to Hold First "Face to Face" Meeting

CHANDLER, AZ -- The World Batch Forum (WBF) User Group will kick off a campaign to expand its membership and activities, when it holds its first "face-to-face" meeting at WBF's annual North American conference in April.

"For the past several years, we've conducted small User Group meetings via teleconference, but we've never held a live session," said Maurice Wilkins, vice chairman of WBF and Users Group coordinator.

"However, for the Users Group to make a genuine contribution to the advancement of batch process automation and to give the vendor community some requirements feedback, we want to attract as many potential members as possible and increase our level of activity. That requires face-to-face meetings, and since many of the people we want to attract to the group will be attending WBF's annual conference in New Jersey, it's the perfect time and place for us to get together," he added.

The User Group meeting will take place Sunday, April 13 at the Woodcliff Lake Hilton in Woodcliff Lake, NJ and is open to all WBF individual and corporate members, who work for "owner/operator" companies User Group meeting attendees do not have to be registered for the conference.

"Among the topics of discussion will be the changing user requirements of batch system users and the role of World Batch Forum and the Users Group in defining and helping the vendor community to meet them", Wilkins said.

"Much of the discussion will be centered on a recent study by ARC Advisory Group on the subject. ARC Senior Analyst John Blanchard is a speaker at the WBF conference, and we certainly welcome his participation in our efforts," Wilkins said.

Anyone seeking more information about the WBF User Group and the April meeting can contact Wilkins at maurice.wilkins@millenniumchem.com.

Mr. Biro is looking for a diverter valve:

I am looking for a divert or multiport valve. The system is a dilute phase conveying line.  We are looking for an option that allows for diverting from one to any of four ducts (4" probably).  We want the switch from one port to another to be able to be done without stopping the system.

Tom needs help scaling up precipitate filtration:

I have a basic lab precipitation and Buchner funnel filtration process for a calcium-phosphate that we manufacture which has been scaled up to the level where we can precipitate and filter up to 2 kg worth of powder (in roughly 80 L of water) per day, in four batches.  We use Whatman type 541 filter paper in the funnels, on a vacuum line.
 
We now need to scale this up, and as we have limited space we are running out of places to put Buchner funnels - and they are not convenient within the context of a production process.  A custom reactor for up to 50 kg/batch I can easily design, but I need to filter it.  At this level a continuous process seems most appropriate and would minimize operator involvement.  I have looked at small centrifuges, but I am not sure if that would be appropriate.  The restriction for me is that there should be no metal-to-product contact as this leads to contamination.
 
Does anyone have any suggestions for any processes which I could look at?  I am based in London, UK.  I remember seeing a screw-press that might have done but I can no longer find the link to the page I saw it on.
