I-positive pressure dense phase pneumatic conveying system isebenzisa umoya ocindezelwe njengendlela yokudlulisa.Epayipini, izinto ezisetshenziswayo zithuthwa ngesivinini esiphansi, isimo sendunduma yesihlabathi, i-fluidization noma isimo se-agglomeration, esibizwa ngokuthi i-positive pressure dense phase transportation pneumatic.
