WhatsApp: +86 18838072829The 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.
WhatsApp: +86 18838072829Characterisation of Separator Efficiency in a Ball Mill Circuit 18. Separator efficiency is defined as specific power consumption reduction of the mill opentoclosedcircuit with the actual separator, compared with specific power consumption reduction of the mill opentoclosedcircuit with an ideal separator.
WhatsApp: +86 18838072829A 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.
WhatsApp: +86 18838072829A 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

WhatsApp: +86 18838072829Figure 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 ...
WhatsApp: +86 18838072829crushed 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.
WhatsApp: +86 18838072829Where the finished product does not have to be uniform, a ball mill may be operated in open circuit, but where the finished product must be uniform it is essential that the grinding mill be used in closed circuit with a screen, if a coarse product is desired, and with a classifier if a fine product is required.
