Pneumatic Conveying Characteristics of Fine and Granular Bulk Solids

On the Electrostatics of Pneumatic Conveying of Granular Materials

In this work the electrostatics of the pneumatic conveying of granular materials in a non-conducting (PVC) vertical pipe is studied using Electrical Capacitance Tomography (ECT) system. The non-conducting wall in general attains static charges arising from particle-wall collisions in the initial periods of conveying process and then reaches equilibrium with the surroundings. The polarity of par...

Microstructural characteristics of planar granular solids

The microstructure of granular materials is the main factor determining their macroscopic behaviour. We study systematically the statistical characteristics of volume elements (called quadrons) of microstructures of monoand polydisperse planar disc packs granular and report a number of new results. The packs analysed were of different intergranular friction coefficients ,μ , contained about 20,...

Pneumatic Conveying System: an Overview

3 Design engineer, Scorpio, Industries ltd., (India) ABSTRACT Pneumatic conveying system has always been economic and efficient means of conveying materials. From the historical background it is evident that there has been a considerable development to that extent where in even high density materials can be easily conveyed. With many advantages over conventional conveying system, it stands in a...

Electrostatics of the Granular Flow in a Vertical Pneumatic Conveying System

The phenomenon of electrostatic charge generation in a pneumatic conveying system was studied. The main parameters used for quantitative characterization of the phenomenon included induced current, particle charge density and equivalent current of the charged granular flow. These were measured using a Digital Electrometer, Faraday Cage and Modular Parametric Current Transformer (MPCT) respectiv...
