Pneumatic conveying moves powder and granular materials through a closed pipeline with air.
Pneumatic conveying moves powder and granular materials through a closed pipeline with air. In dilute phase the material is carried suspended in a high-velocity air stream; in dense phase it moves slowly in dense plugs pushed by compressed air.
Dense phase is advantageous for abrasive and fragile products and long distances; dilute phase is simpler and more economical.
