Vibratory Feeders And Conveyors: Useful Selection Tips

By Rob Yandrick, Eriez Vibratory Products |

Figure 1.  Vibratory feeders are particularly well-suited for fragile or friable materials, and hard-to-convey powders Figure 2. Today’s advanced electromagnetic drives address many shortcomings of earlier designs The need to move, convey and feed materials exists in virtually all segments of the chemical process industries (CPI). Vibratory feeding and conveying equipment (Figure 1) has been used in the CPI for several decades to efficiently move both fine and coarse materials that tend to pack, cake, smear, break apart or fluidize. For instance, in many CPI facilities, vibratory feeders are used to meter precise amounts of product from hoppers, and to gently deposit them on a conveyor or a packaging machine. Vibratory equipment is also used for many types of screening applications, including size separating, scalping or removing oversized product and conglomerates, and for dust or fines removal, as well. Key components In most process applications, materials must be conveyed repeatedly from their point of arrival throughout successive operations within the plant. Feeders, which are often turned on and off repeatedly as needed, are typically placed throughout a plant…
