Studies in fluid energy grinding
M. Ramanujam,D. Venkateswarlu +1 more
TL;DR: In this paper, the results of 239 experimental runs on grinding calcite of particle size range 0.15-1.70 mm in an experimental jet mill of 20 mm diameter, using feed rates of 5-150 g/min and air pressure of 3-6 kg/cm 2 G are reported.
Journal ArticleDOI
Internal pressures in flowing granular materials from mass flow hoppers
V. Lakshman Rao,D. Venkateswarlu +1 more
TL;DR: In this paper, the internal pressure of perspex mass flow hoppers was studied using a radiopill receiving system. But the results were compared with the Jenike-Johanson theory, and the effects of stop/start operation and compaction of the fill material prior to the initiation of flow were also studied.
Journal ArticleDOI
Static and Dynamic Wall Pressures in Experimental Mass Flow Hoppers
V. Lakshman Rao,D. Venkateswarlu +1 more
TL;DR: In this paper, the static and dynamic wall pressures measured by a small pressure sensitive radiopill, in axial-symmetrical and plane-strain experimental perspex mass flow hoppers, are reported.
Journal ArticleDOI
Determination of velocities and flow patterns of particles in mass flow hoppers
V. Lakshman Rao,D. Venkateswarlu +1 more
TL;DR: In this article, an instrumentation set-up for the determination of particle velocities and flow patterns in mass flow hoppers is described, which includes a pressure sensitive radiopill as flow tracer, ferrite antenna system, transistorized tuned amplifier and potentiometric recorder.
Journal ArticleDOI
Studies in vibration milling
TL;DR: In this article, the results of 300 experimental runs on vibration milling of soapstone, graphite, cXte, magnesite, rock phosphate, granite and zirX sand covering particle size range of (−0.25+0.10) to (−1.00+ 0.80) mm, density range of 2.29−4.59 g/cm3, hardness range of 1-7 Mho's hardness number and surface energy range of 4.50−38.66 kgf m/m2, are presented.
