Effects of grinding parameters on product fineness in jet mill grinding
Ritva Tuunila,L. Nyström +1 more
TL;DR: In this article, the influence of several grinding parameters on the product fineness in jet mill grinding was studied experimentally with a laboratory scale spiral type jet mill, and the most significant variables in the jet mill were feed rate, volumetric flow rate of grinding air and the height of an inside classification tube for grinding at constant pressure.

Effect of nozzle inclination on jet attrition
TL;DR: In this paper, the effect of the inclination of a supersonic Laval-type nozzle on the formation of new particle surface was investigated, where a baffle was inserted downstream of the jet tip to test its effect.

Circular fluid energy mill
P.B. Rajendran Nair,M. Ramanujam +1 more
TL;DR: In this paper, an operational matrix was established with its elements representing the particular angle between the nozzles giving maximum performance for a given nozzle size and grinding pressure, and the results and observations were used of to develop a circular fluid energy mill, which can be an efficient alternative to the existing mills.

Analysis of hold-up and grinding pressure in a spiral jet mill using CFD-DEM
TL;DR: In this article, a spiral jet mill was simulated using Discrete Element Method (DEM) and Computational Fluid Dynamics (CFLD) models and the particle behavior and fluid motion were analyzed as a function of hold-up and grinding pressure.
