Prediction of product size distributions for a stirred ...

In this paper, the difference between ball mill grinding and stirred ball milling is discussed. A size-energy model is proposed for simulation of stirred ball milling. The product size distributions below 10 μm from a stirred ball mill were simulated by the model satisfactorily. The model is

Dec 01, 2018  A population balance model originally developed to predict grinding in ball mills by Austin et al., 1984, Rajamani and Herbst, 1984 was used to analyze the test results. The results show the applicability of using population balance modeling in estimating the product particle size distribution from a laboratory vertical stirred mill.

Dec 01, 2006  For the pilot Tower and SAM mills, the slope of the product size distribution described by the (P 90 − P 10)/P 50 ratio remains relatively unchanged whereas the P 80 /P 20 ratio reduces in the whole product size range tested. Visually there is a narrowing of the PSD in the fine particle sizes but it is not as evident as in the pin stirred ...

A Review of Advanced Ball Mill Modelling

mation used to date to describe size reduction in mills. DEM makes it possible to predict how collisions vary in magnitude and frequency as the geometry, the ball charge and the mill speed are varied. Therefore, instead of cor-relating each individual parameter such as mill diameter, filling, speed and ball size, for instance, to the product

The aim of this work was to optimize the ball mill based refining process of chocolate, in terms of refining time and energy consumption. Experiments were planned following a central composite design (CCD), considering refining time (rt) and agitator shaft speed (as) as factors. The experimental variables measured were chosen from the main characteristics that describe unmoulded chocolate.
