Barite-Fluorspar-Zinc Ore Grinding. The ore for treatment is of such a nature that conventional grinding to —65 mesh using a ball mill classifier circuit results in excessive overgrinding of the barite. To avoid this condition a rod mill is used instead of a ball mill for reducing the feed for flotation. This circuit, consisting of a ...Web

Barite is being produced in various region of Turkey, mainly in Adana, Konya, and Isparta that is widely used as oil drilling, painting, paper and plastic sector, etc. In these industries, grinding of barite mineral is needed (Deniz, 2012). It is well known that it is very difficult to reach ultraf-ine sizes by dry grinding in a tumbling ball mill.Web

Recently, we came across some batch grinding size distribution data in the literature that met our requirements for the ball and particle size distributions quite well. The data analyzed in this section were taken from two sources: the M.S. dissertation of Siddique [45] and a project report prepared by Rémillard and Vachon [46].Web
