"The increasing adoption of HPGR in the mining and cement industry is expected to propel the market growth" The global High Pressure Grinding Roller (HPGR) market is anticipated to witness a robust growth owing to the increase in the adoption of the mining and cement industry.
Term high pressure grinding rolls Acronym HPGR Category drive system Application HPGR Definition Grinding equipment that consists of two counter rotating rolls (one floating, one fixed) enclosed in a strong frame. Pressure is applied to the floating roll by means of a hydropneumatic spring system while the other is fixed in the frame.
HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
ABB has manufactured variable speed drive systems for over 50 years. We have delivered more drive systems for grinding solutions than any other supplier, including 125 GMDs, 112 RMDs and 46 HPGRs. We have also increased drive performance through innovation, enabling mills and rollers to become more powerful, productive and profitable.

From high pressure grinding rolls to traditional primary and secondary grinding mills, ABB has worked with the industries leading mechanical suppliers to develop the most efficient and reliable electrical solutions. The electrical design plays a role in determining the most economic and efficient grinding solution for a given plant.
High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
High pressure grinding rolls (HPGRs) have seen an increased global popularity over the past decade, due to the development of more powerful variablespeed drive (VSD) systems. ABB''s VSD solution plays an integral role in providing highthroughput and energy efficient grinding – making HPGRs a competitive alternative to SAG mills.
