The flow behavior of mineral particles through glass funnels

Abstract

In industry the flow of mineral particles in silos playa very important role in the recovery of these particles into containers for bagging and transport. The silo design parameters and particulate properties are restricting the flow behavior in silos thereby controlling the rate of packing into containers as a finished product or else in the utilization of these particles for subsequent unit operations down the processing line. Further, telescopic silos have been introduced recently in mining industry [1] for dust suppression in quarries, gravel pits by minimizing the distribution of dust and fines in to the surrounding areas. There are factors affecting the flow behavior in silos [2] such as particle size, angle of repose. moisture content, static electric charges of powders and so on. In order to simulate the behavior of mineral particulates in silos, glass funnels of different dimensions have been chosen due to their transparency.
