In thermal power stations, nuclear plants, and chemical and industrial plants, different types of bulk materials are used. The materials exist in different forms including lump, powder, granules, chips, and pallets. These bulk materials, in their different forms, require efficient and reliable material handling systems.
The U.S. cement industry produces goods valued at over $10.6 billion and employs nearly 18,000 persons. The U.S. industrial sector accounts for 30 percent of energy use in the United States. If the energy efficiency of industrial facilities improved by 10 percent, EPA estimates that Americans would save over $14 billion and reduce greenhouse gas emissions equal to the emissions from the electricity use of more than 20 million homes for a year.
Portland cement companies combat heavy dust, reclaim product and enhance quality control using a variety of vacuum cleaning applications.
In many industrial plants there are one or more applications with intermittent demands of relatively high volume. One example is the use of dense phase transport systems to convey the cement. Dense phase systems can cause severe dynamic pressure fluctuations affecting quality of the end product in a plant.
In many manufacturing operations, a very significant compressed air use is pneumatic conveying of many types of materials such as cement, fly ash, starch, sugar, salt, sand, plastic pellets, oats, feeds, etc. Often these are systems that use high-pressure air (100 psig class) reduced to lower pressures (15 psig, 45 psig). This creates an air savings opportunity.
Sitting on his desk the day Brian began his new job as Plant Engineer for Carbo Ceramics’ McIntyre, GA facility was a proposal to purchase a new 150 HP air compressor as a backup machine. The facility already had six of these machines and, yes, all six ran almost continuously.
A compressed air system assessment saved this building materials manufacturer over $518,000 per year in energy costs, with a simple ROI of 11 months.
Air cannons, also known as air blasters or just “blasters” belong to a family of products known as flow aid devices. For over 30 years, air cannons have been used widely in industries such as cement manufacturing, electric power generation, coal, metal, and non-metal mining, and pulp and paper manufacturing.
