• ### How to Calculate Grinding Mill Operating Efficiency

In grinding, operating Efficiency compares the operating work index of a comminution machine to the Bond work index from bench scale crushing and grindability tests or/and pilot plant tests. Economic Efficiency is comparing the income from production to the planned income from production. Energy as consumed in comminution machines and the required energy as determined, from bench scale

• 10/9/2017· Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load

• ### Ball Mill Grinding Theory Crushing Motion/Action Inside

In Fig. 4, the equation of the parabola, origin at p1, is y = x tan α1 gx²/2V1²cos²α1 and the equation of the circle of the mill, origin p1, is x² + y² — (2r1 sin «i) x 4- (2ri cos α1) y = 0. The simultaneous solution of these two equations will give the co-ordinates of the point d, where the two curves intersect.
