Manual or mechanical small ball mills should operate 40% full to have good performance. Ball mills are loaded with 1 part of ore, 1 part of water and 2 parts of steel balls . Small balls are best for fine grinding, but big balls help break the larger chunks of ore. Ideally a mixture of small and big ball mill should be used. Always use the same mixture of ball …

Request PDF on ResearchGate | Effect of Media Size in Stirred Ball Mill Grinding of Coal | As a prerequisite to producing super-clean coal with any physical coal-cleaning process, such as microbubble flotation, the feed coal must be micronized to liberate finely disseminated mineral matter.
How Ball Mill Ore Feed Size Affects Tonnage & Capacity
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 per day.
Calculate and Select Ball Mill Ball Size for Optimum …
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”.

As shown in this figure, the breakage rate decreases with decreasing particle size and, more importantly, there is an optimum ball size for each feed size, which decreases with decreasing feed size. - 1.8 'G W 1.2 Q io W a Y a W m 1.4 F- 0.4 ~.
The effect of ball size on mill performance - ScienceDirect
EFFECT OF BALL DOETER Results of many tests suggest that the form of the S function for normal breakage in ball mills is St=Wa (5) It is consequently very convenient to have a more general fitting function which reduces to this for lower values of x, to the left of the maximum shown in Fig. 2.

A typical particle size distribution of the feed to ball mill (from one installation) is given as under. In front of, and inside the first compartment partition in a close circuit ball mill, the following particle size distribution is expected.
Ball mill - Wikipedia
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Ball Mill VS Rod Mill - Xinhai
After long time grinding, the material be grinded to the correct size. For details, the grinding theory of ball mill and rod are different in many ways. For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral.
Mill (grinding) - Wikipedia
SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
