Abstract. The application of vertical mills in regrind circuits is consolidated. This type of mill is now attracting interest in primary grinding applications, due to its higher efficiency when compared to ball mills, which are usually used at this stage. In this study, a coarse sample of iron ore was tested in a pilot scale grinding circuit ...

We observed that, particle size decreased significantly due to regrinding while floatability of the feed was more than discharge. Moreover, floatability of each fraction ( 400, +400325) in mill feed and discharge was studied. Results indicated that, the floatability of all fractions in the mill feed was more than the mill discharge.

PEBBLE MILLS. No steel grinding media is used in a fully autogenous mill. When choosing primary autogenous grinding, run of mine ore up to 200300 mm in size is fed to the mill. When using a crushing step before the grinding, the crusher setting should be 150200 mm. The feed trunnion opening must be large enough to avoid plugging.

For the Vertimill a specialized tumbling test is used (Jar Mill test). I should also point out that if you are thinking of a regrind application then you cannot use the fresh feed (or core for a greenfield project) as a test sample. You do need to perform a laboratory rougher flotation (or whatever is the separation step before regrind).
