  • BASIC KNOWLEDGE STORAGE AND FLOW OF BULK SOLIDS

    STORAGE AND FLOW OF BULK SOLIDS Typical phenomena when bulk solid is flowing out of a hopper or silo are: Mass flow The entire vessel contents are in motion during discharge of the bulk solid. If the area above the hopper is high enough, a uniform sinkage across the cross-section occurs (piston flow). Funnel flowStorage and Flow of Particulate Solids SpringerLink,W.

  • DESIGN OF BINS AND HOPPERS FOR THE STORAGE OF

    funnel or mass discharges. The existence of one type of flow or the other depends on the nature of the particulate solids and the storage container. Designing a bin with a specific type of flow therefore requires jointly considering the characteristics of the material and of the bin itself. 1.1 TYPES OF FLOW 1.1.1 Funnel flowStorage of Bulk Solids in Silos DIETMAR SCHULZE,3 Flow Problems. Typical problems which occur at the storage of bulk solids are: Arching: If a stable arch is formed above the outlet so that the flow of the bulk solid is stopped, then this situation is called arching (figure 3a). In case of fine grained, cohesive bulk solid, the reason of arching is the strength (unconfined yield strength) of
