摘　　要：越来越多的水电站工程位于高山峡谷地区。砂石料加工及混凝土系统布置场地多为山坡地,系统布置时要因地制宜,充分考虑地形地势条件,从高处向低处运送砂石骨料的情况经常出现,下行带式输送机的运用越来越广泛,其运行工况、设计计算和上行带式输送机有所不同。文章重点介绍下行带式输送机的计算及选型。More and more hydropower projects are located in hill and valley areas. The aggregate reclaiming plants and concrete mixing system are mostly arranged on mountain slopes. So considerations shall be given to the system arrangement according to local conditions. It is common to convey the aggregates downward, therefore, the descending belt conveyer is used widely, but its operating conditions, design and calculation are different from those of the ascending belt conveyer. This paper highlights the calculation and type selection of the descending belt conveyer.
