By M. Adams, M. Linnemann– Coal deposits with thin seams and many interlayers can be mined economically by surface miners, which can cut the exact depth of the coal layer and deliver the coal ready for belt conveyance without further crushing.

Windhagen, Germany – West African Guinea is known for possessing the largest reserves of high-quality bauxite in the world. This potential has prompted the country to continually expand its bauxite mining sector in recent years, making substantial investments. Wirtgen surface miners are playing a decisive role in this development process, as many of the country’s bauxite mining operations rely on Wirtgen’s technology as their standard extraction technique.

With the development of a completely new type of crusher, the so-called eccentric roll crusher type ERC25-25, thyssenkrupp has achieved a quantum leap in primary crushing. The new crusher features a particularly flat and robust design and high throughputs of up to 3,000 tons per hour, enabling it to process hard rock and ores efficiently and economically in underground mining operations. As the centerpiece of a mobile or semi- mobile system the eccentric roll crusher also enhances cost efficiency in surface mining. In the future, the new series will be supplemented with further models to enable both smaller and higher throughput capacities for different applications.
