The closedcircuit grinding system of the ball mill is shown as follows: materials mixed in a certain proportion will firstly enter the cement ball mill for grinding and then be sent to the powder concentrator by bucket elevator. The powder concentrator divides the materials into coarse and fine materials.

A ball mill for this throughput would have a diameter of m, assuming it works in a closedcircuit system. In order to assess the economy of the roller mill fin ish grinding process, it is necessary to determine the overall operating costs and compare these with the corresponding figures applicable to a ball mill grind ing process.

A simple and costeffective circuit for a small mill that requires a fine grind is a singlestage SAG or AG mill (no secondary ball mill). The mill is closed with a hydrocyclone (just as a ball mill would be) and may include a pebble recirculation and/or crushing system. These tend to be inefficient, but the simplicity makes them

Closedcircuit ball mills have been operated for cement milling for decades [[7], [8], [9]].Fig. 1 shows the process flow of a closedcircuit, twocompartment cement ball mill. The closedcircuit operation helped to reduce overmilling of particles [10], resulting in lower specific power consumption [11] in comparison with opencircuit operation, where the ball mill is operated without the ...

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 ...

crushed ore is fed into a SAG/Ball mill circuit with a median size of approximately 12,000 microns. Most SAG Mills are operated in closed circuit with a screen. The screen fi lters undersized ore, normally minus ½ inch, to a ball mill discharge sump. The combined mill discharges are pumped to undergo classifi cation, normally via hydrocyclones.
