The reasonable determination of wall pressure is critical for the design of silo structures. In this study, the primary objective is to present four novel wall pressure coefficients based on four true triaxial strength criteria in the quasiplane strain state. These four strength criteria are the Drucker-Prager (D-P) criterion, the Matsuoka-Nakai (M-N) criterion, the Lade-Duncan (L-D) criterion ...


If yes, are there any design standards (preferably AS - Australian Standards) or other documents/journals which detail the design of an explosion vent for a silo, containing coal? (eg: total surface area needed to vent the expanding gasses, etc.) Calculation procedures, examples and so on would be great! kind regards


feeders Pfister® DRW under one coal silo. Block-System Solution A special and economic version of a coal silo with an attached rotor weighfeeder is the so called block-system. It can also be used for online-calibration. The small size reduces coal extraction problems. This solution is useful if the burners are far apart from the fine coal silo.
