  • ACHIEVING HIGH RELIABILITY FROM GRAVITY FLOW

    A. Conveying through a Pipline. There are basically five classification categories for pneumatic conveying systems as shown in our Figure 12 depending on range of velocities and pressures. "Dilute phase" are usually the high velocities and low pressure systems while "dense phase" are the low velocities and high pressure systems. The air-
