HPGR High Pressure Grinding Rolls

The most common HPGR based circuit involves feeding primary crusher product to a secondary crushing circuit with of cone crushers in closed circuit with screens, followed by tertiary crushing with HPGRs, also operating in closed circuit with screens. The product of these two stages of crushing and screening then passes to secondary milling.

Developments in HPGR technology - Mining Magazine

The typical application of HPGR in heap leaching will be replacing the conventional tertiary crusher. With the larger, super HPGR systems of the future, additional metallurgical options exist, shifting more of the crushing load to the HPGR. When processing leachable ores through an HPGR, micro-cracks are created.

Chapter 6 - Roll Crushers - ScienceDirect

As the product size from HPGR is fine, the present trend is to replace the conventional secondary and tertiary crushers with a single HPGR unit. Thus, liberation size is more economically achieved and the product acceptable for down stream operations such as flotation.

First choice for HPGR technology and service

a tertiary crusher (e.g. cone crusher) would produce. The reason is that the compressive force not only acts on the coarse end of the PSD, but throughout the particle bed on both coarse and fine particles, including the fine particles derived from the initially coarser fractions. A wide range of ores appear to generate products of a similar P80.
