circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed 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 ...

Figure shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is ...

Mills can be open or closed circuit. In open circuit, the ore passes through the mill once and on to a classifier which separates fine and oversize material, the former going to a product stream and the latter to a secondary mill. In a closed circuit the discharge flows from the mill to a sump and is pumped to hydrocyclones.

Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turnkey ...

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...
