Analysis and Optimization of Dust Control Hopper System

Abstract

Bulk cargo transportation and loading is one of the common industrial problems because during this process dust spread from cargo to the environment. Especially significant dust concentration is observed in industrial areas such as harbors, cargo terminals, and production areas. Different dust suppression systems are used to reduce the amount of dust spreading in environment during granular cargo loading process. In this paper particle flow through the hopper nozzle is analyzed under different conditions, depending on vibration frequency. Distribution of particles by their size at hopper nozzle outlet is analyzed numerically. Frequency analysis of dust hopper for simplified FEM model is performed.
