  • Pneumatic Cement Conveying Systems

    Dense-phase pneumatic conveying relies on transferring materials at much lower velocities than normally experienced with screw pump conveying technology. The reason is that the Macawber conveying process does not depend on complete fluidisation of the cement and complete mixing of the cement with the conveying air.

  • Introduction to Pneumatic Conveying of Solids

    What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.
