Get Pricemill contents of an autogenous industrial mill was measured in terms of size and mineral distribution, during a survey conducted at LKAB operations in Sweden. The breakage and transport in AG/SAG mills was found to depend on the physical properties and proportion of the different components in the mill feed.
Get PriceEF5BM=[ P80+10.3 1.145×P80] ( 3 ) 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 to ball

Get PriceA suitable ore feed size distribution is critical in order to achieve high grinding efficiency and throughput, especially in the grinding circuits of AG or SAG mills. Plant operators traditionally use visual information about ore appearance and size distribution when making key operational decisions.

Get Price01-01-2016· The feed to high aspect AG/SAG mills are usually preferred from gyratory crushers, while the feed to low aspect mills are preferred from jaw crushers. Depending on the set, the maximum size of the particles discharged from gyratory crushers is about 300 mm and from jaw crushers is about 180–100 mm; thus, the optimum feed size may be taken to range between 150 and 300 mm.
