The Practicability of a Flowability Improvement

Original language description

Essential property in a transport process of a particulate material is flowability in vessels, bunkers, and silos. The flowability as a property influences the creation of falls, such an rching, piping, ratholing in a storage transport system. Elimination of the phenomena, for example by using air pumps and vibrators for existing storage system, is mechanically very ineffective and time consuming. However, coating a small amount of additive, and thereby decreasing the angle of internal friction, is oneway of improvement flow properties of storage particulate materials. Binderless dry and wet granulation of cohesive powders in rotating fluidized beds with the aid of pressure swing is the other way to a flowability improvement by which spherical particles in very narrow size distribution have been created
