:: Donhad Support CEEC to Improve Grinding Efficiency


Extracting a desired grade ore from a complex ore body is a multifaceted task. A fine balance must be struck between achieving desired throughput and product size with a unique mix of ore and grinding media.

Working closely with a grinding media partner is key to accomplishing improved grinding outcomes. Donhad, the most recent company to sponsor CEEC, collaborates directly with its clients to ensure they meet their targeted results. The recently released high carbon grinding media is the result of this close work with clients.

ďCEECís focus on improving grinding efficiency closely parallels Donhadís own work. Advanced grinding efficiency results in increased processing performance. At Donhad we work with our clients to monitor and cross correlate grinding media consumption alongside mill performance. Improved particle size stability, throughput and planning flows from this deeper understanding of the grinding mediaís effectiveness.Ē Paul Shelley, Donhadís Managing Director.

Donhad Pty Ltd is a privately owned company founded in Bassendean, Western Australia in 1965. The company manufactures forged steel grinding balls, engineering forgings and a range of specialised fasteners used by mining and mineral processing industries. Donhad has three manufacturing sites in Australia to provide a reliable supply of top quality grinding balls. The advent of increased grinding media competition - including overseas producers, meeting customer demands for lower cost and higher productivity, steel prices, exchange rates and lowering minerals commodity prices have all played key roles in Donhadís focus on innovation in the grinding media industry.
