  • Ball Mill Grinding Media Options

    Apr 26, 2019A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

  • EFFECT OF AUTOGENOUS AND BALL MILL GRINDING ON

    Abstract. The effects of grinding on the floatabilities of copper-nickel sulfides from Duluth gabbro were investigated. At the same mesh-of-grind copper, nickel, and cobalt recoveries were higher and residual sulfur in the tailings was lower with autogeneously ground pulps. With ball-mill ground pulps the residual sulfur could not be lowered even
