Secondary rock milling can be applied to any ore or rock containing sufficient material which is sufficiently hard in the required size range to be used as grinding media. Automation of secondary rock mill circuits helps keep them operating at optimum capacity by adjusting media addition and feed rate to suit conditions in the mill.
SAG mills usually have a larger diameter than length and are used to reduce large feed size ore (typically ~300mm) down to ~3mm, often for further grinding in a secondary process. Ball mills are smaller in diameter than length and can be used in either primary, secondary or tertiary grinding applications to reduce material from ~20mm to very ...
Autogenous mills can be operated in tandem with secondary grinding mills (either a ball or a pebble mill) or they can be operated as single-stage mills in closed-circuit with a classification or sizing device. If a critical size builds up in the charge of the autogenous mill, it is usually extracted through pebble ports and crushed for recycle. ...
Hammer mill is the most widely used grinding mill and among the oldest. Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer ...
The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these …

18.9.3 Grinding Mill Control in Closed Circuit. The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables.
