The grinding circuits are complex and processing units include vertical roller mills, high pressure grinding rolls (HPGR), tube mills, Horomills and several types of air separators. Studies in several cement plants by a research group at Hacettepe University have shown that the performance of existing circuits can be improved.

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

Abyek cement plant is equipped with four clinker grinding lines; every grinding line consists of a two-compartment tube ball mill. Recently, in a retrofit project, two high pressure grinding rolls (HPGR) units were installed in two grinding lines before the tube ball mills to grind clinker feed. The efficiency of these HPGR units is reported to ...

HPGR Studs-Zhuzhou Cemented Carbide Works Imp. &Exp . Co.-High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and cement industry. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals and cement.

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid […]
