Size Reduction
— It consists of a metal cylinder that can rotate on a horizontal axis and grinding medium (i.e. stainless steel or porcelain balls). Grinding of particles is accomplished by the impact and attrition of the balls in the rotating ball mill. Speed of the ball mill plays an important role in the size reduction process.
