Investigation of Operational Conditions for Fine Grinding of Limestone with a Super Centrifugal Mill

Abstract

In the present work, the fine grinding of limestone was performed by using a super centrifugal mill (SC-mill) which was a kind of circular-type stirred mill. The effects of the grinding conditions in the SC-mill such as the rotor speed, the grinding time, the mass of the grinding media, and the mass of the feed sample (or slurry concentration) on the fine grindability of limestone were investigated. As the results, the mass and the specific surface area of the fine particles produced by the SC-mill could be expressed as a function of the grinding conditions as mentioned above.
