摘要

Chutes are used to direct the flow of bulk solids, e.g., from one conveyor belt to another. Unfortunately chutes all too often "fail" to perform reliably. Such failures can be costly, particularly where large tonnages of bulk materials are handled such as in most mining and quarrying operations, ship and railcar loading and unloading facilities. Some of the problems associated with failed chute designs are plugging of chutes, wear on chute surfaces, unacceptable dust generation, excessive belt wear, and particle attrition. By far the most severe of these problems is plugging. Wear on chute surfaces is often dealt with by providing rock boxes, dusting by providing a dust collection system, and excessive belt wear by providing skirts to control bouncing of large lumps. In fact all of these problems can usually be eliminated, or at least minimized, by judicious use of certain chute design principles. A comprehensive bibliography regarding chute design has been prepared by Roberts and Scott. Using the terminology in their paper, we will only consider the fast (i.e., accelerated) flow made in which material flows in contact with the chute bottom and side walls without contact with the top.
