### Grinding time for ball mills - Grinding Classification ...

2021-6-29 Then take the volumetric feed rate of the new ore per time. Divide the unit capacity by the feed rate and you have the nominal retention time. Say your unit capacity is 1/2 cubic meter and you are feeding 6 cubic meters per hour, your retention time would be about 5 minutes. smartdogmining/. David.

### Analysis Of Grinding Time Of Planetary Ball Mill: No ...

In our fixed mind, the longer the grinding time of planetary ball mills is, the finer the material will be, but during the experiment or production process, the grinding time is not proportional to the size of the material being discharged.
