مصنع لتجهيز البوكسيت/Chromium High Pressure Roller Grinding
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.

Grinding and ultrafine grinding.
Used in mining appliions for the last 30 years, high pressure grinding rolls (HPGR) reduce 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 volume, exceeding its compressive strength with equal pressure being applied to ...
polycom® highpressure grinding roll for grinding of binding agents 5. Full of energy – but efficient! As the grindability of the feed materials increases, so does the effi ciency of the highpressure grinding – and the polycom ® reveals its full potential. In these cases, compared to a roller mill, up to 20 percent of the energy required for grinding can be saved; compared to a ...
High Pressure Roller High Pressure Grinding Roller . Since its introduction in 1985, high pressure comminution with roller presses (also known as HPGR) has been proving its significance in energy efficient crushing and grinding circuits in the cement industry In more recent times, HPGR technology with its technical and economical advantages has not only carved a niche in the process of diamond
· Primary grinding in the highpressure grinding roll increases the capacity of an existing dry ball mill operation. Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode. Hybrid grinding means that a part of the separator tailings (which are recirculated to the ball mill) is diverted and fed to the Polycom together with the fresh feed. Thus, some of the ...
