System Design for Pneumatic Conveying of Solid Material .

pneumatic conveying I. INTRODUCTION Pneumatic conveying is the use of air to transport material through a pipe or duct. Most granular, crushed or pulverized materials may be conveyed by pneumatic systems. In any conveying system, energy is required to accelerate and lift the material and to overcome any friction losses.

Operation of pneumatic conveying systems in technological .

pneumatic conveying enables to control concentration of material and conveying agent in the pipeline as well as the velocity of the diphase stream [3]. Solutions of conveying lines on the basis of pneumatic system devices can be used not only for the conveying of bulk material but also for the performance of technological processes.
