Modeling breakage rates of coarse particles in ball mills

01/06/2009· It is worth analyzing the mass balance equation for the case where the magnitude of the lowest impact energy in the mill is higher than the fracture energy of the toughest particle in the charge. This condition is approached by a mill that is fed with particles contained in a comparatively fine size range when compared to the ball size. In this case, Eq.

Grinding control strategy on the conventional milling

by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure 1 for a schematic of the process flow. The

Metcom Expertise Metcom Technologies

As it turns out, a valid "mass-balance" formula can be derived from the following two questions: A. How much new product is being generated by the circuit? B. How much new product is generated by each pass through the ball mill? Then the circulating load ratio is equal to 'A' divided by 'B', the number of passes through the mill needed to generate the total amount of new circuit product

AMIT 135: Lesson 2 Circuit Mass Balancing Mining Mill

Given the mass and component balance equations : F = C + R. Ff = Cc + Rr. Mass yield (Y) can be solved as a function of the stream, assays which yields the two-product formula: R = F- C. Ff = Cc + r (F C) Mass Yield Formula Example. Mass Yield = 1.5%. Component Recovery. In many mineral processing applications, the focus is to maintain maximum recovery of the valued mineral or element
