Effects of chemical and physical characteristics of powders on their transport.

While designing and developing a project for a means of transport, information are necessary on the material that will be handled on it. This kind of information is obtained through some tests that det. such technol. qualities as: abrasive quality, flowability, powderiness, gas permeability, etc. This article illustrates the relation between the chem. and phys. properties and the characteristics of a material, that projects managers take into account during the design state for the development of a means of transport
