近年来,随着散状物料运输量的增长和物料搬运技术的发展,一种运量大,效率高,能耗小的斗式提升机,即高效斗式提升机已应用于料仓给料、粮食提升等作业。特别是使用了高强度圆环链牵引后,已能制造提升高度超过50m的高效环链斗式提升机。据统计,近20年来,国外已有约500台大运量、大提升高度的 In recent years, with the growth of bulk material transportation and material handling technology, a bucket elevator with large capacity, high efficiency and low energy consumption, that is, an efficient bucket elevator, has been applied to silo feed , Food upgrade and other operations. In particular, the use of high-strength circular chain traction, has been able to raise the hoisting efficiency of more than 50m chain bucket elevator. According to statistics, in the past 20 years, there have been about 500 large-capacity foreign countries that have greatly upgraded their standards
