Global High Pressure Grinding Rolls (HPGR) Market Overview. The Global High Pressure Grinding Rolls (HPGR) Market is growing at a faster pace with substantial growth rates over the last few years and is estimated that the market will grow significantly in the forecasted period i.e. 2019 to 2026.

High-pressure grinding rolls were first applied in the minerals industry in 1985 in cement plants. The main objective for the use of HPGR was the significant energy savings achievable. Today, they are also being used by diamond mines and for the communition of coal as well as for the grinding of slag, iron and chromium concentrates (Figure 4).

Further energy efficiency can be achieved by grinding taconite in a hybrid mode, whereby the material is first ground in a high-pressure roll mill and then in a ball mill. However, optimal partitioning of energy between the two mills is necessary for attaining maximum efficiency. 10 refs., 5 figs.
