Olds Elevator : Impressive Heat Exchanger for Hot Sand

Hudson, NH -- Olds Elevator LLC of Hudson, NH and Palmer Mfg. and Supply Co. of Springfield OH collaborated on a series of trials using an Olds elevator as a heat exchanger for hot foundry sand by running tap water through the hollow shaft of the Olds elevator’s static screw. During normal elevation of hot sand, heat is extracted through the screw by running a stream of low-flow (2 gpm) tap water through the screw shaft.

The elevator/heat exchanger was tested under a range of conditions of sand flow, sand temperature and water flow rates.  Refer to photo of test equipment configuration. A description of the equipment setup is:

Left to right: Olds elevator: 12 foot tall, 5.875 inch ID rotating casing, 5.25” OD static screw with 1.25” hollow shaft. Screw flighting continuously welded to shaft top and bottom. Water line feeds tap water into bottom of screw shaft. Flow is regulated by a valve with in-line flow meter. Elevator controlled with VFD to allow regulation of sand flow rate to a maximum of 5.58 tons/hour

Sand Heater: Electrically heated elements in fluidized bed by compressed air supply. Sand supplied from Olds elevator discharge. Heated sand fed directly to Olds elevator feed hopper.  Sand Heater Controls: Air flow and temperature controls

Examples of the effectiveness of the elevator/heat exchanger at different flow rates:

Hollow flighted screws, in addition to hollow shafted screws, which will triple the surface area of the chilled screw surface in contact with the moving sand.

The Olds/Palmer elevator/heat exchanger will be demonstrated at the upcoming CAST EXPO 2010 in Orlando, FL from March 20-23. The CAST EXPO serves the nations foundry industry.

Hosokawa : Agglomerator for Crop Protection

Summit, NJ -- To ensure good flow properties, a longer shelf life, good dispersibility and wettability (when reconstituted into the liquid phase prior to spreading in the field), pesticides are nowadays mostly produced either as dry agglomerates or as dry, extruded product, having the appearance of either small cylindrical shaped or, after an additional treatment in a Spheronizer, spherical particles.

Agglomerates are produced by thoroughly mixing the micronized, powdery premix with a liquid binder, such that the particles will stick to each other to form larger particles. The eventual grain size (0.3 – 1.4 mm) of the agglomerates depends among others on the ratio of the binder to the powder.

In case of the extruded product, a low-pressure extruder is used, in which an extrudable mass will be pressed through a screen (orifice plate) with perforations of 1-2 mm. The low pressure in which this extrusion takes place ensures, that the extrudates remain relatively porous and therefore maintaining the required good dispersibility.

A humidified feed product with very homogeneous moisture content is essential to achieve optimum extrusion results with a maximum yield and minimum of clogging of the extruder.

For both agglomeration and extrusion process, Hosokawa’s Flexomix is the most suitable equipment. The Flexomix, a high speed, continuous instant mixing equipment, ensures very even, homogeneous humidification of the particles.

In case of agglomeration, the homogeneous mixing in the Flexomix ensures efficient formation of agglomerates with uniform quality, resulting in a high process yield. These agglomerates are porous and slightly irregularly shaped ensuring a good wettability and dispersibility.

The Flexomix has a self cleaning mixing chamber, which minimizes adherence of moist product to the mixing chamber wall, allowing a relatively high liquid addition ratio as required.  The agglomerates formed in the Flexomix fall from the Flexomix into a Fluidized Bed Dryer and are dried to the required final moisture content.

In new plants, the Flexomix is the equipment of choice for both a direct agglomeration process as well as the wetting / humidification step in case of an extrusion process to ensure a maximum extrusion performance.

In a lot of cases, the installation of the Flexomix in existing plants to replace existing (less effective) agglomeration or humidification devices has also proven to be very successful to significantly increase the yield and reduce the down time due to e.g. clogging to a minimum.  The Flexomix is used by major water dispersible granular crop protection agent producers world wide.

Bemis acquires Alcan Packaging Food Americas

Neenah, WI -- Bemis Company, Inc. U.S., Canada, Mexico, Brazil, Argentina, and New Zealand which recorded 2009 net sales totaling $1.4 billion. These facilities produce flexible packaging principally for the food and beverage industries and will augment Bemis' product offerings and technological capabilities. The transaction is expected to be accretive to both diluted GAAP earnings per share and adjusted earnings per share, beginning in 2010.

Under the terms of an order signed by the U.S. District Court for the District of Columbia on February 25, 2010, two of these facilities, located in Menasha, Wisconsin and Tulsa, Oklahoma, must be divested. The 2009 net sales associated with the facilities to be sold was approximately $100 million.

"We are pleased to welcome our newest Bemis employees and look forward to integrating these new facilities into our business," said Henry Theisen, Bemis President and Chief Executive Officer. "During the next two years, we expect to generate strong cash flow which we will use to invest in growth opportunities, pay down debt, and deliver attractive total returns to our shareholders. This acquisition complements our manufacturing capabilities and technological expertise around the world. We are looking forward to an exciting and successful 2010."

Mr. Lee needs help characterizing material lumps:

Is there a standard for the designation and characterization of material lump size?

For example I am working on a project with material lump sizes specified as +12mm to -35mm and +35mm to -65mm. Is this correct and what does it actually mean?

I thought that when characterizing and specifying material lump size it would be something like +12mm to -35 micron stating that max lump size is 12mm, minimum 35 micron?

Thanks,
Ian Lee

Director of Sales and New Business Development

Engineer with sales experience to develop new customers and support existing customers for use of our powdered metal in the medical and depositional (LASER & EB) for aerospace/defense. Using a proprietary process we manufacture fine and ultra fine powdered metals already selling to most medical device use and many aerospace companies in the US and internationally with an almost 40 year history of providing quality product. We are the only manufactures using this process and produce the most pure, nonporous and spherical powders.

Your position would primarily be developing a new customer base and occasionally contacting existing customers. Compensation would be based on salary and commission that would produce a six figure income with full benefits. We are looking to fill this position by the end of February and have already reviewed quite a number of resumes.

The successful candidate would receive complete training and introduction to existing customers who are primarily fortune 100 companies.  This is a great mid-level position for someone eager to develop a long-term career in sales and rapidly advance to a management position. Experience in nonferrous metal powder a plus.

Good quality control relies on proper sampling, which must be accurate and precise and truly represent the main body of biomass. Without good sampling, quality control is based on false information. Bulk materials are difficult to sample properly on a production basis... (Click here for more)

This week's photo is of an FLSmidth Bucket Chain Excavator (BCE). The BCE is designed particularly for sticky bulk materials. The store consists of two or more longitudinal stock piles stacked according to the Windrow method. While one pile is being stacked, the other is reclaimed at right angles to the direction of stacking.
