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 3000 tph, enabling it to process hard rock and ores efficiently and economically in underground mining operations. As the centerpiece of a mobile or semimobile 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.

Torsten Gerlach, CEO of the Mining Technologies business unit of thyssenkrupp Industrial Solutions, said: “Our customers are looking for dependable, safe and easy-to-install crushers that permit maximum productivity even underground. To meet these requirements we have combined our many years of experience with different crushing technologies and our comprehensive engineering expertise. The new eccentric roll crusher from thyssenkrupp offers a wide range of possibilities for effectively processing ore and hard rock both underground and on the surface as part of mobile and semi-mobile systems.”

One of the key advantages of the new crusher is its flat and compact design with integrated screen. It is 20 to 50% lower than conventional primary crushers. This greatly simplifies transportation, installation and maintenance below ground. If required, the crusher’s height can be reduced further for installation by removing individual components, saving additional time and costs.

The newly developed and patented design featuring a roll mounted eccentrically between the crushing and the screening chamber offers greater efficiency and productivity compared with other crusher types. The large, constant stroke of the ERC25-25 crusher combines with the integrated screen to provide very high crushing intensity and throughputs of up to 3000 tph.

In the large crusher infeed area, the material to be reduced is divided into two material flows: The first with fine material is screened out and passes through the screening chamber to a discharge conveyor. The second stream with coarse material is transported to the crushing chamber and reduced between the eccentrically mounted roll and the chamber walls.

In addition to higher production, this design also requires less maintenance. Keeping the fine material out of the crushing chamber reduces the power consumption of the electric motor and significantly reduces the load on the machine. An integrated automatic gap adjustment system with overload safety device also offers good protection in the event of non-crushable foreign material.

The arrangement of the roll permits the eccentric roll crusher to be balanced with great precision. With additional balancing weights it can be balanced almost completely. This lowers machine vibrations when idling and significantly reduces the loads on surrounding structures compared with other primary crushers. That makes the new crusher ideal for use in mobile crushing systems.
