Abstract: Based on the continuous plane-strain deformation of an isotropic, frictional, cohesive, compressible solid, a rolling theory for granular solids has been developed. The pressure exerted by the ...

Abstract: This paper presents the mathematical theory of stress and velocity fields for the steady gravity flow of bulk solids in converging channels. The basic equations based on the concepts of soil ...

Abstract: The flow of bulk solids such as ore, coal, sugar and salt from storage bins depends on the pressures exerted by the bin walls on the solids. In the past the flow properties of bins have ...

Abstract: The paper discusses the settlement of powders in a vertical channel due to the escape of gas from the solid. The governing equations are discussed along with the methods of solution. Experimental ...

Abstract: It is proposed that three loading conditions should be considered in the analysis of loads acting on a bin: Initial loading which occurs when bulk solid is charged without any of it being ...

Abstract: This paper describes a bin for feeding dry calcine dust at a uniform rate of up to 90 TPH directly onto a belt. A small amount of air is injected into the bin to ensure controlled flow. ...

Abstract: Problems of undesirable vibrations in an ore unloading structure are described. Earlier unsuccessful attempts to eliminate vibrations by changing allegedly exciting frequencies mechanically and by ...

Abstract: This is one of a series of papers by the authors on the loads exerted by bulk solids on the walls of containing vessels. In this paper, design formulas and charts are presented for mass-flow ...
