Studies on the Grinding Kinetics of Limestone Ore ...

The present study is focused on the grinding kinetics of Limestone ore. During the process of achieving the required particle size of the material with required properties, grinding process is considered to be an energy-intensive stage in the overall process. Large amounts of energy consumption is the major problem in grinding in grinding process.

A study of the grinding of magnetite/limestone mixture in ...

May 01, 2021  For the limestone (b), the breakage rate followed the first-order breakage kinetics at the grinding time range of 0 to 14 min. With a further increase of the grinding time, the breakage rate of limestone deviated from the first-order breakage kinetics. S 1, L decreased as the amount of magnetite increased in the mixture. The relationship ...
