:: Compact, Robust and Powerful: New Crusher from Thyssenkrupp Revolutionizes Material Processing in Both Underground And Surface Operations
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 semimobilesystem 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.
Innovative design for greater efficiency
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 3,000 tons per hour.
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 tothe crushing chamber and reduced between the eccentrically mounted roll and the chamberwalls.
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.
Low-vibration machine also offers advantages in mobile use
The symmetric 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.
