ball mill and screening of iron ore
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones. get price
process and design of ball mill
Design Method of Ball Mill by Sumitomo Chemical Co., of motion for each. In a ball mill, the collisions between two balls or a ball and the mill wall are expressed by a Voigt model that expresses elastic spring (spring coefficient K) where elastic and inelastic properties of the objects are introduced between the points of contact as shown in Fig. 1and the viscosity .
