Summary:Handling of bulk solids is a difficult and costly challenge that many industrial firms face today. Erratic or nonexistent flow of material, segregation, or flooding of fine powders all affect the bottom line. Flow problems can cause delays in the startup of a new plant, or contribute to excessive downtime in an existing plant, which in turn impacts production schedules and productivity. Poor product quality and spoiled material also result from unreliable equipment and processes -- undermining efficiency and diminishing profits. Although bulk-solids flow problems add millions of dollars to the operating costs of thousands of companies every year, flow of solids is rarely an area of study for university engineering students. A key focal point for bulk-solids technology is the silo. In its most general sense, that term encompasses bins, bunkers, hoppers, moving-bed reactors and other structures used to store, feed, and, in some cases, process powders and other bulk solids.
