The Critical Porosity of Free Flowing Solids
(The American Society of Mechanical Engineers (ASME), 1969)The behavior of samples of free flowing sand under applied shear stress have been investigated in an annular shear cell of novel design. Measurements of critical porosity, dilation and shear ... -
Failures of Reinforced Concrete Grain Silos
(The American Society of Mechanical Engineers (ASME), 1969)In recent years many reinforced concrete grain silos have suffered serious damage either from inadequate foundations, or from incorrect reinforcement of bin walls, or from faulty structural work. ... -
Pressures on Silo Walls
(The American Society of Mechanical Engineers (ASME), 1969)Overpressures up to four times the static pressure have been measured during discharge of sand from a model silo. The overpressures can be associated with the fundamental flow patterns. Design ... -
Adhesion and Agglomeration of Solids During Storage, Flow and Handling—A Survey
(The American Society of Mechanical Engineers (ASME), 1969)During storage, flow and handling of solids, particles in the micron range tend to adhere to walls or to each other. Such processes can cause severe disturbances and sometimes require the ... -
Theory of the Formation of Arches in Bins
(The American Society of Mechanical Engineers (ASME), 1969)The flowing of the granular materials in bins is governed, particularly in the case of small ratios of aperture diameter to particle size, by the constant formation and breaking down of arches, ... -
Gravity Flows of Ideally Plastic Materials Through Slots
(The American Society of Mechanical Engineers (ASME), 1969)Experimental evidence shows that plasticity theory is a suitable framework for analyzing the flow of bulk materials in bins and hoppers. It thus serves as a rational guide for the collection ... -
Flow Patterns of Granular Materials in Flat-Bottom Bins
(The American Society of Mechanical Engineers (ASME), 1969)Bins with flat bottoms and multiple openings are commonly used in industry to store granular solids because of their lower cost and because they occupy smaller vertical space than bins with ... -
Analysis and Design of Plastic Storage Tanks
(The American Society of Mechanical Engineers (ASME), 1969)The author has designed over one hundred major tanks that store plastic powders and pellets. This article gives some practical examples of how to analyze and design plastic storage tanks. ... -
Effect of Initial Pressures on Flowability of Bins
(The American Society of Mechanical Engineers (ASME), 1969)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 ... -
Investigations on the Movement of Fuel Elements in the Core of a Pebble Bed Reactor
(The American Society of Mechanical Engineers (ASME), 1969)For several years gas-cooled high temperature reactors have been developed in Germany, the main feature of which are their pebble-type fuel elements. The pebble bed is in the state of a ... -
Experience With Nonmechanical Solids Flow Control Device in the Waste Calcining Facility
(The American Society of Mechanical Engineers (ASME), 1969)Large volumes of radioactive granular solids are being safely and efficiently handled, pneumatically, on a production scale in the Waste Calcining Facility at the Idaho Chemical Processing Plant. ... -
Air Pressure in the Bulk of Granular Solid Discharged From a Bin
(The American Society of Mechanical Engineers (ASME), 1969)Air pressure different from that in the surrounding atmosphere develops in the bulk of granular material flowing out of an open bin through the bottom orifice. When measured on the axis of ... -
An Investigation of the Gravity Flow of Noncohesive Granular Materials Through Discharge Chutes
(The American Society of Mechanical Engineers (ASME), 1969)The flow of granular materials through curved or straight discharge chutes is classified as either “fast” or “slow.” Fast flow is the more efficient and occurs when the material flows in ... -
Investigation of Silo Loads in Measuring Models
(The American Society of Mechanical Engineers (ASME), 1969)The test results described are a portion of a current comprehensive series of investigations. No attempt is made to produce the values for wall frictional and bottom loads, which were measured ... -
Limit Plasticity Approach to Some Cases of Flow of Bulk Solids
(The American Society of Mechanical Engineers (ASME), 1969)Depending on the stress state, a bulk solid, regarded as the elastic-plastic material, can exhibit workhardening, worksoftening or perfectly plastic properties. During continuing motion, the solid ... -
On the Design of Oscillating Conveyers
(The American Society of Mechanical Engineers (ASME), 1969)The paper studies the conditions of conveying material on an oscillating trough. Two criteria for estimating the efficiency of different designs of such conveyers are proposed. The analysis of ... -
Stresses in Wedges of Cohesionless Materials Formed by Free Discharge at the Apex
(The American Society of Mechanical Engineers (ASME), 1969)Cohesionless wedges formed by free discharge at the apex exist completely in the active critical state. With active failure movement, sections only of the wedge may be in the active state. ... -
On the Theory of Bin Loads
(The American Society of Mechanical Engineers (ASME), 1969)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 ... -
Effect of Injected Air on the Rate of Flow of Solids
(The American Society of Mechanical Engineers (ASME), 1969)Injected air facilitates flow of a noncohesive powder through an orifice. The effect of injected air on the flow rate of raw-mix powder (used in cement production) through an orifice has been ... -
A Study of Factors Affecting the Performance of Screw Conveyers and Feeders
(The American Society of Mechanical Engineers (ASME), 1969)A study of the literature on screw conveyers and feeders has been made. Most of the work is concerned with conveying material and in these cases the degree of fill in the trough is kept ...
