Abstract

Pneumatic conveying is one of the most important techniques for the manipulation of particulate or powdered materials in the industry. This method has many advantages such as greater flexibility, simplicity of operation and lower cost if compared to other techniques of particulate handling. The objective of this work is to check the modification of the characteristics (particle size, angle of repose and apparent density) of calcitic limestone in an industrial scale pneumatic conveying system. It was verified by means of standard tests that the characteristics such as apparent density and effective diameter decreased by 22% and 7%, respectively, from the cycles with the material through the line of the pneumatic conveying system, and the angle of repose, even after abrasion of the material in the system, there were no significant changes.
