Commercial ball sizes 10 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dV = 0.40 KF dB = ball size (cm) F = feed

and with the decreased grain size, the necessary ball size also decreases (Olejnik, 2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both
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 quot;Emerging Trends in Mineral Processingquot;, 2005, is

the feed particle size is 15 to 25mm; Suitable for coarse grinding, the upper limit of particle size is 1~3 mm; Application range the first section grinding of two stage (or three stage), especially suitable for processing brittleness ore materials.
In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size
In the large and medium sized mining project, when grinding fineness is less than 0.15 mm, the two stages grinding process is the economy method, and the product particle size composition is uniform. gold ore ball mill. In gold ore beneficiation process, many crushing, grinding and beneficiation equipment will be involved.
General diameter of ball mill is in accordance with a formula hard ore. 5 times of feed particle size, such as,if the feed granularity is 20 mm,the steel ball generally choose 100 mm. Medium hardness ore. 4 times of feed particle size , such as, the feed granularity is 20 mm,the steel ball generally choose 80 mm.

Objective The dimensional properties of iron ore pellet feed including specific surface area and particle size distribution in the ball mill was studied using response surface area method.
The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is
F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles.  But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
