Laboratory Attritor Grinding Media GRINDING MEDIA SELECTION OF MEDIA There are only three real factors controlling the choice of media: How heavy it is, (specific gravity, typically in g/cm3) How big it is, (diameter, usually expressed in millimeters or mesh size) What it is made of (strength, wear life, abrasiveness, inertness, cost)

The motions of grinding media and powder in an attritor canister were studied by means of filming the agitated charge and frame-by-frame scrutiny of the footage. In conjunction with auxiliary experiments, this permitted semiquantitative analysis of the milling action. In particular, the mill can be divided into several regions characterized by different balances between direct …

Grinding is an energy intensive process and grinding more finely than necessary wastes energy. Cement consists of clinker, gypsum and other components mostly more easily ground than clinker. To minimise over-grinding modern ball mills are fitted with dynamic separators (otherwise described as 'classifiers' or more simply as 'separators').

Within the attritor mill the grinding media motion is driven by rotation of the impeller arms and, depending on the operating impeller speed, the media can act either as a solid or as a fluid. Fig. 14 shows the solid fraction of the media bed visualised across vertical and horizontal sections as a function of both impeller design and impeller ...

Positron emission particle tracking (PEPT) was used to investigate the grinding media dynamics in a laboratory-scale attritor mill in the absence of powder. The grinding media motion was analysed as a function of the equipment’s typical operating parameters: impeller speed, impeller clearance and bead fill level. It was observed that the impeller speed had the …
