thyssenkrupp - New Crusher Design Combines Low Profile With High Output

A new crusher recently unveiled by thyssenkrupp is expected to “revolutionize” material processing in both underground and surface operations, according to the company, which describes its ERC25-25 series model as a quantum leap in primary crushing.
thyssenkrupp said the first model to be released can provide throughput of up to 3,000 metric tons per hour (mt/h), and the line will be supplemented with additional models to enable both smaller and higher throughput capacities.
A key element of the new crusher is its flat, compact design and integrated screen. It stands 20%–50% lower than conventional primary crushers, according to the company — simplifying transportation, installation and maintenance in underground applications. If necessary, its height can be reduced further for installation by removing individual components.
The patented design features a roll mounted between the crushing and the screening chamber. Material entering the crusher infeed area is divided into two streams: Fines are initially screened out and removed on a discharge conveyor; and coarse material is transported to the crushing chamber and reduced between the eccentrically mounted roll and the chamber walls.
The company said the large, constant stroke of the ERC25-25 combines with the integrated screen to provide high crushing intensity. In addition to higher production, thyssenkrupp said keeping fine material out of the crushing chamber reduces motor power demand and significantly reduces the load on the machine. An integrated automatic gap adjustment system with overload safety device offers protection against non-crushable foreign material.
The symmetric arrangement of the roll permits the eccentric roll crusher to be balanced with high precision. In fact, with additional balancing weights, it can be balanced almost completely, according to the company. This reduces machine vibration when idling and significantly lowers stress on surrounding structures when compared with other primary crushers — making it well suited for mobile crushing systems.
Torsten Gerlach, CEO of the Mining Technologies business unit of thyssenkrupp Industrial Solution, 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 offers a wide range of possibilities for effectively processing ore and hard rock both underground and on the surface as part of mobile and semimobile systems.”
