Fig. 5 shows the variation of size class 1 (M1) with the milling time for the two feed size distributions. For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate.

How Coarse Can Ball Mill Feed Be Grinding. Feeding 15mm to a ball mill this size is not typical - much larger ball mills 21 or 7.0m diameter typically get 12-16mm feed from what I have seen in my experience With regards to 3.5 - 4 media, typically for Ball mills of this size 16, max size of ball used should be around the 50-60mm.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of …

One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm. An empirical model from "Emerging Trends in Mineral Processing", 2005, is ...

For this work, our objective is to identify a feed size distribution from which maximum production of the target size can be achieved. Just to shed light on the target size, the mill product is defined by three classes; m 1 the feed size, m 2 the target size (−150 + 25 µm) and m 3 being the fines (<25 µm).

Wet Grid Ball Mill | Capacity: 0.5-500TPH Feed Size: ≤25 mm.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
