ball mill grindability

Steel Slag - an overview | ScienceDirect Topics

Preliminary work was carried out by using a laboratory ball mill to investigate the grindability of the steel slag and OPC clinker when ground separately and interground for periods of 30 and 60 min. OPC clinker having particle sizes in the range of 8.0–13.2 mm and steel slag having particle sizes in the range of 8.0–13.2 mm and 2.34–4.75 ...

Back To The Grind: World Cement Grinding Q&A with Fives ...

Apr 15, 2021· Nevertheless, in some instances, for raw meal grinding, the conventional ball mill remains a more appropriate solution, in particular in cases where there are large differences in the physical properties (grindability) of the different components in the raw mix or high abrasiveness of some components. With this perspective, Fives has developed ...

Steel Glossary | Glossary of Terms | Platts

This measure of grindability of coal was developed by an American, Ralph M. Hardgrove. The test involved indicates how difficult it would be to grind a particular coal to a certain particle size. Grindability is assigned an oH value (eg. 55oH), and the smaller the numerical oH value, the more difficult the coal is …
