Development of Roller Conveyor Design for Reducing Energy Consumption Review

Abstract

In the realm of bulk materials handling, roller conveyors are one of the most used technologies. Bulk products such as coal, cement, ores, and grains are often transported using these systems across processing plants or to storage or shipping facilities. With a maximum standard roller width of 275 cm, roller conveyor systems may stretch for tens of kilometres (108 inches). Driving such systems requires a lot of energy and, as a result, releases a lot of toxins into the environment. The study's goal is to examine the most important aspects that influence power consumption in such systems and to come up with solutions that can reduce power consumption during the design process. The most relevant elements on roller conveyor power demand were researched and summarized as a first stage, based on a literature review. System design characteristics (such as idler roll material, trough angle, idler spacing, idler roll diameter, and idler roll bearing type), operating circumstances (such as roller speed), and environmental conditions are all elements to consider (as ambient temperature). Calculations of a roller conveyor system's power requirement are made under various working situations using typical inputs used in the mining sector. To study the relevance of these parameters and their interaction effects on power demand, the estimated values were analyzed in a factorial design.
