cement grinding high pressure grinding roll efficiency

High-efficiency cement grinding International Cement Review

More than 65 of the presses are working in highly-efficient clinker grinding systems around the world. By using the POLYCOM as a stand-alone grinding machine (finish grinding circuit) a reduction in specific power consumption of around 50 per cent compared to conventional ball mill circuits is achievable.

Comparing energy efficiency of multi-pass high pressure

Benefits of using high pressure grinding rollsEnergy efficiency is the main benefit of HPGR. Large energy savings of around 20-50% relative to dry grinding ball mills have been achieved in the cement industry (Otte, 1988;Patzelt, 1992); however, such savings have not been reproduced in the minerals industry when comparing HPGR with wet grinding ball mills. Direct energy savings of around 10-20

Circuit high pressure grinding rolls (HPGR) in a cement

Summary: In this paper, the performance of a closed circuit HPGR operation was evaluated by the data obtained from six measurements in a cement grinding circuit operating in Turkey. Flowrates of the streams and classifier performance were evaluated after mass balancing. The average specific energy consumption of the HPGR for six measurements was 9.62 kWh/t for grinding from 17.9 mm to 57 µm
