Ball Milling Theory Introduction: Figure 1: Ball milling terminology I was first given the formula for gunpowder by my Uncle at age 14, after he had observed my apparent obsession with class C fireworks Being a scientist who had experimented with the ancient recipe himself during his youth, he thought I should try making my own fireworksequation for ball mill circuits • Define and calculate the classification system efficiency of a ball mill circuit • Define and calculate the grinding efficiency of the ball mill in a ball mill circuit • Relate overall ball mill circuit output and circuit efficiency to specific design and operating variablesMODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLINGThe physical constants used in these calculations are given in Table 1 In a discrete element method simulation of the inside of a ball mill, the coefficient of friction of the balls is the most important factor, and it has been reported that the spring coefficient and damping coefficient calculated from Young’s modulus and PoisDesign Method of Ball Mill by Sumitomo Chemical Co, Ltd
