DISCRETE ELEMENT METHOD MODEL OF THE FIRST BREAK

mechanical properties may affect the size reduction process. The discrete element method (DEM) is a numerical modeling technique that can be used to study and understand the effect of physical and mechanical properties of a material on processing. The overall objective of this study is to develop a DEM model of the 1st break wheat milling process.

IsaMill Wikipedia

The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft loed along the central axis of the mill.
