    Abstract : Handling of granular material occurs all over the world for different reasons and under different conditions. In the mining industry, granular material handling is present in almost all processes. The machinery that deals with the granular material is typically subjected to significant wear. The loading process is a very crucial task in any mine. READ MORE
