2004-1-14  The maximum fineness attainable by open circuit stirred mill tests is 6200 cm 2 /g. #x02022; During the open circuit tests, specific energies excessively increases beyond Blaine values of 4500 cm 2 /g which corresponds to a specific energy consumption of 60 kW h/t. Beyond this point, further grinding can be obtained for the speeds above 600 rpm.

Even in open circuit, there is no such general rule, because it depend on the mill and its charge and all its internals, and even the grinding aids. A very simple model would assume a specific power consumption proportional to the finenes, for low finenesses, and a saturation when the fineness reaches a certain level.

open-circuit grinding, closed-circuit grinding - Xinhai

2020-1-15  The open-circuit grinding is suitable for the first grinding. The material discharged from one section of the rod mill enters other grinding equipment and is then ground (fine). In this way, the first section of the rod mill has a smaller crushing ratio and higher production capacity, and the process is relatively simple.

Comparison of open and closed circuit HPGR application

In general the material fed to the circuit has a top size of 50 mm which is very coarse for the ball mill. For this purpose, later in 1980s, high pressure grinding rolls (HPGR) has found applications as a pregrinder which increased throughput of the grinding circuit at the same fineness. In early applications, HPGR was operated in open circuit.
