Typically, feed to rod mills comes from closed circuit crushing with screens with a top size of 1 to 1¼", or 25 to 32 mm (F80 of 15,000 to 20,000 µm). Deviations above this size have often been associated with extremely poor efficiency, as measured by the Bond Operating Work Index, especially on ores with high Bond Laboratory Work Indexes.

Target Particle Size To Save Feed National Hog Farmer. The participating farms and mills feed about 580 000 hogs/year. The team found that the average micron size of feed ground in a hammer mill was 916.5 microns. Roller mills averaged 720 microns. The location of feed manufacture was also significant.
mean particle size (in microns or µ) is commonly referred to as the "average" or the "micron size". Another common calculation performed in the size analysis procedure is to determine the "log-normal standard deviation". For most feed materials ground through a roller mill, the log-normal
CIRCUIT AND MODEL DESCRIPTION The grinding mill circuit and model used to test the performance of feedforward control is described next. The grinding mill shown in Fig. 1 consists of three elements: mill, sump and hydrocyclone. The mill is supplied with mined ore (MFO), water (MIW ), steel balls (MFB) and underflow from the hydrocyclone.
In order to explore the influence of voltage on the particle size distribution of chalcopyrite ore, the high voltage pulse discharge breakage experiments were carried out under the feed particle size of −12.5 + 10 mm, pulses numbers of 60, voltage varying from 95 kV, 120 kV, 145 kV, 170 kV and 195 kV, as shown in Fig. 4, Fig. 5.

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.
The roller mill produces a more uniform particle size distribution with lower a proportion of fines (GMD, <500 μm) than the hammer mill (Nir and Ptichi, Reference NIR and PTICHI 2001), although the particle size and spectrum may vary with the type of corrugation on the rollers and the type of the grain (Martin, Reference MARTIN 1985).

The example below shows a particle size distribution with 5% oversize. Here, 95 % of the particles are below 1 mm, the oversize has a size of 1 - 1.25 mm. This can be quantified by Q3 (1 mm) = 95% or 1-Q3 (1 mm) = 5%. This example also shows that the addition of oversize increases the mean particle size, while the median remains unchanged.

The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions. For light ball loads the ball mill is less efficient as might be expected.
