Abstract In view of the need to improve automation and weighing accuracy solid energetic materials in process, reduce process safety risk automatic conveying loading equipment control ability, a weight-loss pneumatic vibration device is designed, which adopts method weight loss measurement. Through sensor installed on platform, hopper fed back controller real time, The obtains reduction per uni...

In this study, the degradation of wood pellets and dry roasted coffee beans in a pneumatic conveyor was evaluated for high-speed impacts. The change particle size generation fine particles were used as an indicating parameter degradation. A four-bends industrial scale conveying system study lean phase conveying. effects operating parameters on investigated, including velocity concentration. exp...

Modeling of pressure drop in fluidized dense phase conveying (FDP) powders is a tough work as the flow comprises various interactions among solid, gas and pipe wall. It difficult to incorporate these into model. The depends on flow, material geometrical parameters. existing models show high error when applied other pipeline configurations varying lengths or diameters. current study investigates...

Aiming at the problems of high energy consumption and particle breakage in pneumatic conveying process large-scale breeding enterprises, this paper, based on theoretical calculated value suspension velocity, a computational fluid model discrete element are established dynamics (CFD) method (DEM). Then, through numerical simulation gas-solid two-phase flow, influence four factors wind speed, mas...
