requirement of air pressure in pneumatic conveying system

  • a :

    Pressure Systems The basic components of a pressure system are a rotary air lock feeder valve, a high pressure air compressor system or a low-pressure positive displacement blower or fan to serve as the power source A pressure vessel, the conveying line, and the receiver make-up the balance of the systempneumatic 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 loss.
