Common types of grinding mills include Ball Mills and Rod Mills This includes all rotating mills with heavy grinding media loads This article focuses on ball and rod mills excluding SAG and AG mills Although their concepts are very similar, they are not discussed here Photographs of a glass ended laboratory ball mill show action of ball mass within the mill
The EF4 formula requires both the rod mill and ball mill work index rod mill Wi is used to calculate the optimal feed size and because this is a single stage ball mill calculation, the F80 is actually the rod mill feed size 10,000 µm from Table 1 and the P80 is the ball mill circuit product The EF5 factor only applies below 75 µm
The effect of scats on ball mill productivity was tested and it was concluded that scats may not have an adverse effect on productivity in secondary ball mills and composite mills, if large balls are present The use of a trommel on the ball mill is suggested to solve related problems in the classification circuit
After closed circuit secondary crushing, the SAG mill feed 80 passing F80 size was 25 mm to 30 mm Installed grinding power is split equally between the two mills with the SAG mill fitted with a variable speed drive VSD

ﬁrstly predicted using the SAG mill feed F80 and the ball mill cyclone overﬂow P80 Morrells model Morrell, 2011 relates the feed, mill geometry and operating conditions to the speciﬁc energy of the circuit However, the F80 is not enough to represent properly different size distributions, because different size distributions can
The secondary grinding stage consists of a ball mill fed with material coming from the SAG circuit Finally, a tertiary grinding stage consisting of a ball mill in closed circuit is fed from the secondary grinding stage The secondary and tertiary ball mills have individual classification stages where the cyclone overflow reports to
mills and onto the secondary ball mill circuits, alleviating a common bottleneck There are, however, different methods of making a circuit board Some professionally made circuit boards use a different method to remove extra copper from the circuit board The mill removes the copper around the wires on the board This leaves extra copper
SAG Mill Grinding Circuit Design A variant of this method is to direct pebble crushing circuit product to the ball mill sump for secondary milling: while convenient, this has the disadvantage of not controlling the top size of feed to the ball mill circuit
