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.

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.

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.

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.

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.
