The devices used in classification processes are called classifiers. They are matched to the grinding machines in close circuit for operating over- and undersize particles accordingly. Classifiers are nearly always used to enhance and close the final stage of grinding and so strongly influence the performance of these circuits.
The hammer mill will produce discharge in the 20-30 mesh size. If additional size reduction is needed, a ball mill is a conventional choice instead of the hammer mill. Take a look at …
Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

The purpose of a gold mill, at least a simple one, is to crush and grind rock fine enough to release small particles of gold. After liberating the gold from the rock or gangue, it is then run through a gravity separation step, which will concentrate most of the gold and wash off the lighter waste rock. Step 1.

(Horst 1985, p. 3A-5). Average grinding sizes for the ore can be brought down to 10-15 microns at the very most, if using long grinding periods on a product which has already passed a -200 mesh sieve. Some specific mills are reported to be available, which are capable of grinding the ore down to sizes of 5 microns or less.

Here is a trick for knowing if your flotation feed grind size is fine enough to achieve adequate mineral liberation without doing a full mineralogy study. If your key mineral is sufficiently liberated, it should float and be recovered in the first few minutes in an initial %mass that stabilizes quickly = the green curve. ... Grind Size & …
Tune the grinding circuit to only grind fine enough to attain the commercially-viable liberation size. If gold is found in the 200-300 or <325 mesh fractions, it is likely gold-bearing sulfides or free milling gold <~400 mesh. This gold is not practical to recover via gravity concentration, so flotation or leaching could be used. Additional notes
