Investigation on the Relations of the Dynamic Parameters of Dense-phase Pneumatic Conveying with Plug Flow System

Base on the dense phase pneumatic conveying experiment of cement, the relations among plug pressure, plug velocity and plug length were investigated. The result showed ,with a given plug velocity, plug pressure increased when plug length increased and ,with a given plug length ,plug pressure and plug velocity have the same relation. The ratio of solid and gas velocity may be assumed to be 0.9 in industrial application.
