This concise technical primer explains the principles, equipment, and practical applications of using moving air to transport solid materials. It surveys system types and components—air pumps, exhausters, filters, dischargers, pipelines, and nozzles—then examines design details, typical installations for grain and coal, and specialized conveyors including induction and steam-jet systems. Practical issues such as discharge of wet or sticky materials, dust separation, and portable or floating installations are addressed through experimental observations and illustrated examples. The book aims to guide engineers, works managers, and students in selecting and applying pneumatic conveying solutions across industrial contexts.
