WebAlthough design requirements such as storage capac- ity, throughput, overall height, and other spatial features are important inputs, other critical parameters — including powder cohesion, coefficient of sliding friction, and perme- ability — can significantly affect the bin’s design. Figure 1 illustrates a typical bin installation. The design of a new bin takes into account the cohesiveness of the bulk solid, headroom or footprint constraints, segregation concerns, the likelihood of degradation over time (e.g., caking or spoilage), and discharge rate requirements.
