  • Pneumatic Conveying Characteristics of Fine and Granular

    Fine and granular products possess significantly different pneumatic conveying characteristics. Fine products usually have smooth conveying characteristic curves from dilute-to dense-phase. Between dilute-and dense-phase there is a pressure minimum curve.

  • Pneumatic transport of granular materials through a 90

    01-11-2004· Pneumatic conveying is an important process in the food and pharmaceutical industry for transportation of granular particles. The transport phenomenon of the conveying process in gas–solid system is not fully understood despite numerous studies, both experimental and numerical, have been conducted on different pneumatic conveying systems to characterize the flow profiles of the solids in

  • Granular Attrition due to Rotary Valve in a Pneumatic

    Pneumatic conveying system The experimental setup used in the study was the same as the pneumatic conveying system used by Yao et al. (2004). Granular material was introduced into the rotary valve and entrained by air flowing from the compressor mains. The conveying pipe was made of transparent PVC material and had a wall

  • Material handling of granular and powder ingredients in

    Transfer via pneumatic conveying . Granular and powder ingredients are transferred within and between stages by use of pneumatic conveying. This type of conveying occurs generally within and between the unloading and processing stages. There are four types of pneumatic conveying used, and which method is used depends on many factors.

  • Pneumatic conveying of granular solids in horizontal and

    Computational fluid dynamics simulations are used to investigate the pneumatic conveying of granular solids through an inclined pipe at different inclinations. Model predictions agreed reasonably well with the measurements reported by Tsuji and Morikawa in 1982 for mean gas and solids velocities. The results of influence of model parameters, inclination angle, and feeding conditions on the

  • Electrostatics of the Granular Flow in a Pneumatic

    The phenomenon of electrostatic charge generation and its effects on granular flow behavior in a pneumatic conveying system was studied. The main parameters used for quantitative characterization of the phenomenon were the induced current, particle charge density, and equivalent current of the charged granular flow.
