Calculate and Select Ball Mill Ball Size for Optimum Grinding
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”.

Standard Sizes For Ball Mills
Ball Mill An Overview | Sciencedirect Topics. 3.5.2.2 ball mills. the ball mill accepts the sag or ag mill product. ball mills give a controlled final grind and produce flotation feed of a uniform size. 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.

Particle Size Distribution of Grinding Mill Products
The ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. 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.

SAG Ball consumption is “average” at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t. Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved. You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill. The ore is “hard” and “bulky”.

Ball Mill Loading
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%

The Effect of Ball Size Diameter on Milling Performance
An investigation was conducted to determine the effect of the ball diameter sizes on milling operation. A laboratory size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2 mm +1.4 mm

Need help figuring out which size ball mill I need.
Here is a print. I need a ball mill to cut this radius. I cannot seem to figure out the effective cutting diameter for any standard size ball mill. I am going to make some calls tomorrow but I figure I will see what the knowledgeable people here have to say. Thanks in advance.

Supervisory expert control for ball mill grinding circuits
The general objective of mill circuit optimization is maximizing the feed rate at a stable product particle size. Ball mill grinding circuit is a typical multi-in-multi-out (MIMO) system characterized by time-varying and nonlinear. Much work has been done to control grinding process variables.

Why use Different Size Balls in a Mill
In test 3, in which the grid was used to segregate the different sizes of balls, a further advantage of about 4 percent in efficiency is shown. The conical mill in test 4 increased the efficiency to 58 percent more than in test 1. The efficiency with the long (6-foot) conical mill was about the same as with the short (3-foot) one.
