Two-stage method for the simulation of the comminution process in a high-speed beater mill [PDF]
The paper presents a two-stage simplified method for the simulation of comminution process which takes place in a beater mill. The first stage of the proposed method is a simulation of the flow of gas and ore particles through a mill based on a two-phase

Study of Comminution Kinetics in an Electrofragmentation Lab-Scale Device
A significant challenge in mineral raw materials comminution is the improvement of process energy efficiency. Conventional comminution techniques, although globally used, are far from being considered power-efficient.

Study of the Effect of the Mineral Feed Size Distribution on a Ball Mill Using Mathematical Modeling [PDF]
In this paper, the effect of the feed size distribution was studied for a ball mill. Copper ore of 0.5% was tested using batch-grinding tests. Samples were carried out using three reconstructed feed size distributions in an experimental ball mill.

Particle Size Distribution Models for Metallurgical Coke Grinding Products
Six different particle size distribution (Gates–Gaudin–Schuhmann (GGS), Rosin–Rammler (RR), Lognormal, Normal, Gamma, and Swebrec) models were compared under different metallurgical coke grinding conditions (ball size and grinding time).
