The embodied energy in steel grinding media was found to add 15% to 40% on top of the electrical energy consumed by the mill. Together, the embodied energy of the grinding media and ancillary power added 45% (average) to the electrical power of the mills and crushers. By calculating these values, they can be visualised using the Comminution ...


to specific ball/SAG mill operations. Mill capacity, ball size and other parameters are used to select and specify the design features for each installation. Besides removing worn grinding media from the ball mill discharge and saving energy, trunnion magnets have other advantages that appeal to SAG mill operators:

SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear - the sound of the mills standing still.

Grinding Media - Growth Steel

Media to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.


Steel wear calculation. The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off ...


The even wear allows for the new life potential of media rejected from ported SAG mills. The rejects are totally recyclable since the media retains their integrity for ongoing deployment in a secondary mill. Recycling to a ball mill as supplementary media or possibly as resale to other users provides additional value for our clients.


This relation is used to evaluate the impact liner wear. Abrasion liner wear is evaluated using the procedure suggested by Radziszewski. To have the experimental data, a laboratory mill is used. A small specimen is inserted in the liner face of the laboratory mill to measure its wear during the mill operation.


Ball Mill Principle. The ball mill machine is mainly composed of cylindrical cylinder, end cover, bearing and big gear ring. Cylinder: The cylinder is filled with a ball mill grinding media (steel balls or steel cylpebs) with a diameter of 25mm-150mm. The loading capacity is 25%-50% effective volume of the whole cylinder.
