Ball Mill Circulating Load

As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw. The operator can be misled to conclude that the mill is overloaded due to the ...


Leaking Mill Shell Bolts

The cause of the bolts leaking is running the mill with a density that is to light or feed that requires a high impact to grind. This could either be due to hard or large ore. "Leakers" are common on SAG and AG Mills as well as Rod and Ball Mills. This extra impact on the liners will come from the rods because there isn't enough fine ore ...

An improved method for grinding mill filling

The height from the trunnion base to the mill roof can be used to calculate the mill diameter, although the accuracy by this method is lower than a direct measurement of diameter during a mill entry. The centreline length ( CLL ) can be used to calculate the belly length L using the equation: (7) L = C L L - D - T FE 2 t a n α FE + t a n α DE
