Austone is a supplier of fine grinding media to the mining industry for use in stirred mills, we have a history of successful use in mines across Australia.

Stirred Mills are used in fine and ultra fine grinding as they are an energy efficient alternative to regrind ball mills and the media used in these units has a major influence on their performance.

Austone Quartz media is a highly effective option, our product is comparable with Zirconia media beads in terms of hardness. Austone grinding media can be utilised in fine grinding mills for the size reduction of sulphide or oxide material and coal.

The media is classified as inert and sub angular to sub rounded sphericity. It is hard, strong and durable making it ideally suited as a fine grind media with no effects on the pulp chemistry of the ground product.
