Pittcon 2007 Fast Approaching

Pittsburgh, PA -- Pittcon 2007, February 25 to March 2, at McCormick Place, Chicago, Illinois, builds on past successes while offering exciting new opportunities for conferees and exhibitors in all aspects of this year’s Conference and Exposition.

This year’s Technical Program Technical Program, which includes more than 2,000 technical presentations, continues to focus on core analytical areas of chemistry and on analytical techniques driving advances in the life science arena.

Dr. Charles M. Lieber kicks off the 2007 Technical Program with a Plenary Lecture, “Nanowire Nanoelectronic Devices for Detection of and Interfacing to Biological Systems.” The ACS Division of Analytical Chemistry (DAC) is hosting four invited symposia, four contributed sessions, and an undergraduate poster—a new addition to Pittcon’s dynamic and diverse Technical Program.

Another notable highlight is the new Networking Sessions for Conferees which provide an additional opportunity for conferees with similar interests to meet in an informal venue to discuss new techniques, resolve problems, or brainstorm new ideas.

The Short Course program, with more than 100 courses in nearly 60 topics from which to choose, complements the educational aspect of the Conference. In addition to an expanded offering, the Pittcon registration is waived for those conferees who take three or more Short Courses.

The Pittcon organizing committees continue the long standing tradition of introducing changes every year to enhance the conferee and exhibitor experience, and the Exposition is no exception. This year, the poster session is in the center of the floor for increased visibility, exhibitors are permitted to use overhead lighting in booths, and the registration area is located on the expo floor to allow for easier access to the exhibits.

WEIMA : Shredding of Bulky Plastic Containers

Fort Mill, SC -- The WEIMA Group has developed a new version of the WLK 12 single-shaft shredder for the size reduction of bulky plastic containers and parts with thin gauge wall thicknesses like totes, barrels, drums, tanks, etc. The compact design of the machine includes a new press-down device that enables the customer to shred even the largest size totes without the need to pre-cut.

This new single-shaft shredder is equipped with a doghouse design hopper that is open over top of the rotor. Whole Pieces are directly loaded into the front of the machine. After the container is loaded into the cutting chamber the integrated press-down device will ensure that the part is situated in the bottom of the shredder. The horizontal ram pushes the material into the rotor parallel to the down stroke of the press-down device.

Both pressing actions are controlled by sophisticated electronic controls that ‘read’ the amp-load on the main motor and optimize the pressure applied to the cutting rotor. This optimization acts to keep material in constant contact with the rotor. The WEIMA “V” Rotor provides tight tolerances between the rotor and the stator knife to ensure proper size reduction. When material is shredded small enough it will pass through a screen that is mounted under the rotor. At this point, the material can be further granulated if desired.

The working width of the WLK 12 is 1,200 mm (47.2”). This size machine can handle intermediate bulk containers and other large totes along with materials in sizes up to 1m x 1m x 1 m . The V-Rotor that is utilized on this machine has a diameter of 368mm (14.5”). The main drive of the WLK 12 is either equipped with a 37kW (50hp) or a 45kW (60hp) motor to achieve capacities of 600-1,000 kg/hour (1,300-2,200 lbs/hour) with screen sizes from 20mm-100mm (3/4”-4”). The machine weighs approximately 7500 kg (16,500 lbs). Alternative sized machines are available upon request.

The machine can be used for other applications like purgings if the optional press-down device is disengaged.

The WEIMA Group has been building size reduction equipment for more than 25 years for many different customers and applications around the globe in the plastic, wood and recycling industries. The product range that is produced by the WEIMA Group includes the following products: single-shaft shredders, 2 and 4-shaft shredders, grinders, granulators, briquetting machines, complete systems and auxiliary equipment.

Jenike & Johanson Courses at ASME/AIChE Meeting

Tyngsboro, MA -- Jenike & Johanson engineers will be presenting their popular powder and bulk solids handling courses for American Society of Mechanical Engineers and American Institute of Chemical Engineers (ASME/AIChE) meeting in Las Vegas, Nevada on March 27-29.

Visit http://www.asme.org/education for complete details and on-line registration. Additional public offerings in 2007 include New York city, Houston, and Atlanta.

The training will include discussion of hopper flow patterns, testing of powder flow properties and their relation to bin design, feeder design principles, handling of fine powders and fluidization, segregation of bulk solids, transfer chute design, and the proper use of flow aids. The third day will include a discussion of the fundamentals of pneumatic transport and how to troubleshoot and solve problems with a poorly operating pneumatic conveying system.

Proper training of personnel involved in solids handling and processing is essential to operating an efficient and reliable bulk solids handling system. Since the theory of bulk solids handling is seldom a part of formal engineering training, many in industry lack an understanding of why solids handling problems occur and what practical steps can be taken to diagnose, alleviate, or prevent them.

Training helps to foster greater awareness of operating efficiency, safety, and process improvement, along with an understanding of the reasoning behind required equipment modifications or upgrades.

Fritsch Premium Line of Laboratory Planetary Mills

Idar-Oberstein, Germany -- Once again Fritsch is proving its leadership in the technology of laboratory ball mills. The new Pulverisette 7 premium line is revolutionary in all its features and represents a new standard in laboratory sample preparation.

The most important change involves the positioning of the grinding bowl. The unique self locking principle allows the bowl to be sunk into the sun disk of the planetary mill. Previously it was clamped onto the sun disk.

Apart from enhanced performance improvements in operation and safety of planetary mills was another essential development objective. The self locking grinding bowl mounting makes planetary mills as easy and safe to operate as laboratory centrifuges.

The display offers a wide choice of different languages Many customers will appreciate the new safety features. Our intention was to eliminate any possible errors in operating the mill.

Many other unique features characterize the new benchmark premium line. USB, Bluetooth and Ethernet interfaces allow communication with computers. For instance, users in the pharmaceutical industry can validate grinding processes and monitor them by computer.

Special lids are now available for all bowls to ensure pressure-tight grinding. This also allows grinding of sensitive materials in inert gases such as argon or nitrogen.

Fritsch employees 70 highly qualified staff in production and sales support providing a high level of expertise in all aspects of the product range which is manufactured here in Idar-Oberstein. Fritsch offer comprehensive assistance in several languages to meet the needs of distributors and end users of Fritsch equipment in 136 countries world wide.

Mr. van Kanm wants with screw conveying alumina:

Please help, I have had a request from a client to convey alumina using a screw conveyor set at an angle of 25 degrees. My understanding is that alumina aerates easily and then flows like water and I am not sure it can be transported at this angle in a standard screw conveyor.

The arrangement is:  Alumina is fed from a 5 m3 hopper using a 350mm diameter screw conveyor - 5m length (20 ton/h) at an angle of 25 degrees into a mixer. From the mixer the output is fed into another screw conveyor (20ton/h) set at 10 degrees and that feeds into a 2 m3 bin.

Material:  Cell-grade alumina
Density:  1.1 ton/m3
Grain size:  0 - 0.5mm
Water content:  0%

Any comments will be greatly appreciated. (to post reply, click here)

Mr. Horn needs help with bagging compost:

My wife and I operate a non-profit organization in Southeastern Connecticut for equine retirement. Our farm is on about 130 acres, we currently have 26 retired horses and are planning a considerable expansion in the near future. We have been in operation only two and a half years and have already surpassed our initial business plan goals for our first five years.

We apply organic practices on all our pastures (which has been an uphill battle, as the farm was seriously neglected for years prior to our taking it over). The current herd, as healthy and well fed as they are, provide us with an abundance of manure which we compost and spread on the pastures regularly.

Being non-profit, we rely on fund-raising events, grant writing, an annual appeal and other income efforts. It occurred to me that local gardeners might just be interested in composted and bagged horse manure (judging from the frequent requests for barrels and pick-up loads), especially if it supported a good cause.

My questions for you are, what types of equipment are available for this kind of packaging, is used equipment ever available, financially what is involved, is a building required?  We currently have a substantial Massey Fergusen tractor, spreader, and available barn space.

Any information you can share would be welcome. A phone call might be more efficient so I've included several numbers below. I've also included our website.  Thank you in advance, and I hope to hear from you.  (to post reply, click here)
