High pressure grinding roll (HPGR) technology has become an acceptable size-reduction option for many global mining projects to increase ROI while taking advantage of significant ESG benefits. In general, the mining community understands how an HPGR works and its benefits. However, since the number of installations is somewhat limited with many coming online over the next few years, there is much to learn about overall HPGR circuit design and ensuring the entire system will function as expected.  

This presentation will review HPGR project design considerations to ensure a robust system ready to produce at startup and for the duration of the mine. The focus will be on HPGR circuits containing screens, partial product recycling, or air classification to review potential issues to consider as part of the project design. Some of the items covered within specific HPGR circuits will include material handling, dust generation, automation, screening, tramp metal reject and transfer points. It will also cover general HPGR considerations around testing, spares and service, which will play a role in overall installation success from commissioning through long-term operation.

Utilizing actual field experience and lessons learned from HPGR sites now in operation, the webinar aims to help ensure the best possible outcomes for projects coming online in the future.
