Working together to improve plant performance.


Refurbishing a high-pressure grinding roll (HPGR) brings clear benefits to the customer. A refurbishment costs less than a new supply, yet can offer a similar service life. Refurbishments are done in local workshops, which allows for better control of logistics, quality, and schedule. Moreover, the refurbishment process can be extended to include ongoing improvement and optimization. Over time, this benefit increases as the thyssenkrupp team becomes more and more familiar with the customer’s plant.

An Australian customer asked ­thyssenkrupp to carry out a total refurbishment of their HPGR. thyssenkrupp were asked to deliver the refurbishment instead of the original manufacturer because the HPGR’s previous performance had not come up to the er’s expectations. As the HPGR was third-party equipment and not a thyssenkrupp design, the refurbishment project presented an extra challenge that required close collaboration between the regional office in Australia and the design teams in Germany. The refurbishment was carried out within the ­thyssenkrupp Service Center in Australia, while parts were provided by thyssenkrupp Germany – a highly successful example of working together for the customer’s benefit. This Australian customer was very happy with the way the entire project was carried out and the enhanced performance of the HPGR.

The experience gained on this HPGR project has provided the thyssenkrupp service team in Australia with new options for refurbishing this type of third-party equipment. In addition, the design and implementation processes developed during this refurbishment project are now being shared with other thyssenkrupp Service Centers globally. By working together so closely within its global network, thyssenkrupp is engineering high-quality service solutions that bring the customers long-term added value.

Refurbishments are done in local workshops, which allows for better control of logistics, quality, and schedule.

The bottom line: Refurbishing a high-pressure grinding roll (HPGR) brings customers cost- and time-saving benefits as well as improved control of logistics and quality. Close collaboration between thyssenkrupp teams in Australia and Germany made an all-in HPGR refurbishment possible at an Australian site and brought the customer the added value of a comprehensive engineering solution.
