The topic of combustible dust hazards in bulk solids processing plants has never been more — pardon the expression — explosive. In February this year, a dust cloud explosion triggered a fatal blast and fire in the Imperial Sugar Company's Wentworth, Georgia, plant, generating a storm of media attention, public outcry, and governmental scrutiny. The blast, while more severe than most, was reportedly not a freak incident but the latest in a 25-year string of similar incidents at manufacturing ...

The collection and testing of dust samples is a long‐established practice used by many powder and bulk processors to make informed dust collection decisions. Dust testing protocols have not changed markedly in recent years. The importance of dust testing, however, has changed, and the implications are significant. While knowing your dust has always been good practice, it is rapidly becoming a necessity in today's regulatory climate. This article will review two separate types of testing: (1) ...

Improving the Cleaning Cycle in Baghouse Collectors
ABSTRACT: Background The reverse pulse jet baghouse has been around for over 45 years and the cleaning cycle has not changed very much since that time. The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In a generic baghouse, the cleaning system is comprised of a blowpipe that is located typically approximately three inches above the bag, with an orifice and a venturi, which is ...

Ineffective Cleaning in Generic Baghouses
ABSTRACT: Background In a typical “generic” baghouse application, the cleaning is accomplished by back-flushing the filter with compressed air that travels through an orifice hole in a purge tube (blow pipe) and through a venturi. A typical generic cleaning system allows dust to be filtered at an air-to-cloth ratio of 5:1. That means for every 5 CFM of airflow, there is 1 square foot of media used to filter the air. This has been the industry standard ...

And traditional compressed air hoses simply blew unwanted debris around. So Pendleton teamed up with an inventor, and in 1954 introduced the first air-operated vacuum ...

The cement is pneumatically conveyed to the top of the silos. The valves on top of these silos are normally opened or closed periodically. However when they require the valves to open or close, it is necessary for them to be able to do so without trouble and they need to be assured that the valve will close tightly. The reason they require these valves to close tightly is that in many cement production facilities each silo may contain a different grade or formula of cement. If the valve leaks ...

INTRODUCTION - Helical rotor turbine flow meters outperform flat-bladed rotors by extending the linear range of the flow meter. Manufacturers who produce flat-bladed rotors do so for economic reasons, at the sacrifice of performance. In addition, the helical blade profile transfers energy more efficiently, reducing bearing wear and pressure drop and their associated cost.

As the main consumer of electricity in a wastewater treatment plant, the aeration system weights most heavily on the costs of operation. Climatic changes, the 2007/08 rise in the costs of energy, and the public support for green initiatives have raised the level of awareness for our use of energy, and this has spread far beyond the circles of the environmentally concerned: energy efficiency has become one of the decisive factors in the selection of process equipment. Rightly so, because the ...

Application Considerations for Point Level Monitoring of Powder and Bulk Solids
The use of point level monitors for powder and bulk solids in modern industry dates back to 1934. Resilient to be sure and this exemplifies the critical importance of point level monitors and their use. But what is “point level monitoring”?
“Point Level Monitoring” is the monitoring of presence and absence of material at a predetermined point within a bin, silo or other vessel containing a powder, granular or ...

Continuous level measurement is about one thing, e.g. answering the question “how much stuff do I have”. There are many applications where you need to know how much material is in a bin, silo or other vessel type. Usually the desired engineering unit is expressed in terms of volume or weight. “Measuring” volume or weight is not always the most practical approach, sometimes it isn’t even viable. Take those silos you have, how do you weigh the ingredients if the silos weren’t installed with load ...
