F. Delogu, G. Mulas, in High-Energy Ball Milling, 2010. 5.2 Fundamentals of mechanical alloying processes in ball mills. A ball mill is a relatively simple apparatus in which the motion of the reactor, or of a part of it, induces a series of collisions of balls with each other and with the reactor walls (Suryanarayana, 2001).
Ball Mill Power Load Relationship. The working characteristics of a wet ball mill can be directly described by the useful power consumed.When the mill and its rotating speed are fixed, the theoretical calculation and actual test results show that there is a certain relationship between the active power of the ball mill motor and the load of the ball mill.With the increase of the.

Ball Mill Power Load Relationship. calculating a grinding circuits circulating loads based on screen analysis of its slurries compared to solids or density based circulating load equations a more precise method of determining grinding circuit tonnages uses the screen size.
ball mills, the reason for the huge dif-ference in circuit efficiencies shown by the Davis relationship suddenly became clear. With the low circulat-ing load, the ball mill was relatively full of fines (P80 product size or finer material). Therefore, most of the grinding energy of the mill was be-ing wasted. With the high circulating
