ABSTRACT

The energy consumption of modern belt conveying systems has reduced considerably over the past few decades. Although extensive research has been conducted into the production of energy-efficient belt conveyors, significant scope remains to further reduce the energy consumption, especially when heavily loaded or long overland belt conveyors are considered. A new rail-based conveyor system has been developed to reduce the energy consumption of heavily loaded and long overland conveyors. The new technology is aptly named the Rail Conveyor due to its combination of two well-established transportation technologies. The Rail Conveyor merges the benefits of both belt conveyor technology and rail transport to produce an energy-efficient and cost-effective bulk material transportation system. This paper presents a comparison between the energy consumption and motion resistances of the Rail Conveyor system and conventional belt conveyors. The Rail Conveyor is a continuous bulk material transportation system that, due to track wheels running on steel rails, shares a rolling resistance similar in magnitude to railway systems. Due to the effective elimination of the indentation rolling resistance and belt and bulk material flexure resistance within the Rail Conveyor system, an approximate reduction of 50% in energy consumption can be achieved when compared to conventional belt conveyors.

摘要

在过去的几十年中，现代皮带输送系统的能耗已大大降低。尽管已经对节能带式输送机的生产进行了广泛的研究，但仍然存在很大的范围来进一步降低能耗，尤其是在考虑了重载或长距离陆上带式输送机时。已经开发了一种新的基于轨道的输送机系统，以减少重载和长陆上输送机的能耗。由于新技术结合了两种成熟的运输技术，因此被恰当地命名为“铁路输送机”。铁路输送机结合了皮带输送机技术和铁路运输的优势，以生产出节能高效且经济高效的散装物料运输系统。本文介绍了铁路输送机系统和常规皮带输送机的能耗和运动阻力之间的比较。轨道输送机是一种连续的散装物料运输系统，由于履带轮在钢轨上运行，因此其滚动阻力的大小与铁路系统相似。由于有效消除了轨道输送机系统中的压痕滚动阻力以及皮带和散装材料的抗挠曲性，与传统的皮带输送机相比，能耗可降低约50％。具有与铁路系统相似的滚动阻力。由于有效消除了轨道输送机系统中的压痕滚动阻力以及皮带和散装材料的抗挠曲性，与传统的皮带输送机相比，能耗可降低约50％。具有与铁路系统相似的滚动阻力。由于有效消除了轨道输送机系统中的压痕滚动阻力以及皮带和散装材料的抗挠曲性，与传统的皮带输送机相比，能耗可降低约50％。
