thyssenkrupp Industrial Solutions, one of the leading engineering, construction and service provider for industrial plants and systems, and Maschinenfabrik Gustav Eirich have agreed to cooperate on the further development of the EIRICH TowerMill, a highly energy-efficient agitated media mill for the wet grinding of ores and minerals (Fig.). The aim of the partnership is to build high-capacity, powerful TowerMills capable of delivering high throughputs even for fine and superfine grinding.
Technological requirements in mines are growing ever more complex. Mineral deposits around the world contain ever-decreasing ore grades combined with increasingly finegrained ore bodies. The partnership is thyssenkrupp and EIRICH’s response to the rising demand for grinding equipment capable of achieving a high degree of mineral liberation at ever higher throughput rates.
EIRICH acquired the license to market TowerMills from the Japanese Kubota Corporation in 1999. Today the company supplies TowerMills of various sizes up to a power rating of 1500 hp. Worldwide over 40 mills with a combined power rating of 26 MW have been installed. Together with thyssenkrupp, the expanded product line will include units of up to 6000 hp to guarantee the processing of fine and ultrafine grained minerals of < 20 μm at high throughput rates. EIRICH TowerMills are an important addition to thyssenkrupp’s existing one-stop product portfolio, which ranges from primary crushers to ultrafine grinding mills.
