Full definition
Steel vessel for temporary bulk-material storage with gravity discharge. Critical design factors: wall angle (45–70° depending on material angle of repose), flow pattern (mass flow vs. funnel flow), and anti-arching provisions. Internal liners: UHMWPE, rubber or stainless steel to reduce friction and adhesion. Capacities: 5–5,000 m³. Poor design causes hang-ups, segregation and premature wear.
