1. Introduction

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters.

Mechanical alloying of Si and Ge in a planetary ball mill

Aug 10, 1994The external parameters geometry and frequency of a planetary ball mill were adjusted in order to minimize the duration of mechanically induced Si-Ge alloy formation. Experimental results were compared with theoretical calculations on impact energies and milling power. It was found that a planetary

Study on particle size and X

In this work, micro and nano B 4 C powders were prepared by high energy ball milling. The effects of milling parameters on particle size and X-ray peak ratios were investigated using response surface methodology (i.e. central composite design). Central composite design was implemented to determine the effects of milling parameters (milling time, ball to powder ratio and milling speed) on the

Sep 01, 2012Ball milling is one of the most common unit operations used for size reduction across a range of industries. However, it is also a notoriously inefficient process, often contributing substantially to operational costs. In this work, we investigate the influence of rotation rate, grinding media fill level and grinding media size on the optimal production of a product of intermediate size.
