Ask an Expert
Baghouse versus cartridge dust collectors
 
Q: What factors should we consider when deciding between a baghouse and a cartridge dust collector?
 
David Renfert, Axis Engineering LLC says:
 
A quick search in any venue related to the dust collection industry will uncover a number of divisive opinions and experiences on this question. Perhaps the question is better phrased as, "When should someone choose to use a cartridge dust collector instead of a 'traditional' baghouse dust collector using bags and cages?" The answer is straightforward:
 
A cartridge dust collector should be considered instead of a traditional baghouse when the application has space limitations and the operating conditions match those in which cartridge dust collectors exhibit the best performance. I emphasize the word and because space considerations or equipment costs are often the driving factors in purchasing decisions, and sufficient consideration isn't given to the potential problems that can occur with this type of dust collector.
 
 
David Renfert, PE, is a consulting mechanical engineer at Axis Engineering LLC, a consulting practice headquartered in Kansas City, Mo.

Feature
How a pressed-in and bolted-on strain-gauge weighing system functions
 
 
In the world of inventory monitoring in dry bulk storage bins, steel tanks, and other vessels, weight-measurement systems calculate the material weight in a vessel by converting a distance or level measurement to volume and then to weight. Weight-measuring systems, on the other hand, directly measure the material weight. This eliminates conversion errors that often occur in indirect weight measurement using level-measurement sensors. As a result, weight-measuring systems have an advantage — and are often required — in applications where high-accuracy material measurements are essential.
 
However, a drawback to directly weighing material in a vessel is the difficulty and expense of retrofitting an existing vessel with conventional weighing sensors (load cells). Strain-gauge sensors that can be pressed in or bolted onto the vessel's support structure simplify this task and reduce its cost. Unlike conventional stationary load cells, which are typically mounted under a vessel's legs or other support members while the vessel is lifted by a crane or other equipment, pressed-in and bolted-on strain-gauge sensors are simply attached to the vessel's legs or other support members. This eliminates a need to lift the vessel and may even allow it to remain in use during sensor installation.

Fine grinding with air classifier mills
 
 
photoAn air classifier mill combines a mechanical impact mill with a dynamic air classifier. Ideal for large-volume continuous processing, the mill is one of today's most widely used grinding machines for reducing dry fine chemicals, food products, and other materials. After describing the air classifier mill's applications, operation, and common variations, this article explains how you can adjust the mill's operation to control the final product's particle size.
 
Size reduction equipment for processing dry bulk materials is available in several types and can produce coarse, medium, fine, or ultrafine particles. This article concentrates on air classifier mills, which produce fine particles with a nominal top size of 45 microns or finer, depending on the material.
 
An air classifier mill applies impact grinding and air classification in one step. The mill uses airflow to convey feed material to the mill's grinding chamber, classifies the material into fine and coarse fractions, recirculates the coarse fraction for further grinding, and conveys fine particles out of the mill, all in one continuous operation.
 
For more information on air classifier mills you can read “How to operate an air classifier mill to meet your fine grinding goals” by Rob Voorhees, Hosokawa Micron Powder Systems, in the June issue of Powder and Bulk Engineering.

Article explains green technique to synthesize silver nanoparticles
 
In "Greener Techniques for the synthesis of Silver Nanoparticles using Plant Extracts, Enzymes, Bacteria, Biodegradeable Polymers and Microwaves," published in ACS Sustainable Chemistry and Engineering, authors Rajender Varma, Mallikarjuna Nadagouda, and colleagues describe how plant-based extracts, such as from green tea plants, sunflowers, coffee, and others, can be used to synthesize silver nanoparticles. These materials can replace the toxic substances normally used to create the particles. The methods also eliminate undesirable by-products and reduce energy consumption. Study authors received funding from the EPA. To download the article, click here.
