Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Aug 15, 2012 · ball mill rpm - posted in Newbie Questions: ok so I know this is a question I should be able to figure out on my own I thought I know of some web sites that had the equation but I must have been wrong any way the jar is 7.75 inchs wide and 10.5 inchs long and I`m using 50 cal round musket balls for media (it will be half full of media) so what rpm should I run it at Thanks so much

2. Literature Ball mills are cylindrical or conical shell rotating about a horizontal axis, partially filled with a grinding medium such as natural flint pebbles, ceramic pellets or metallic balls. The common classification of ball mill is any type of mill in which mild steel or iron balls are used.
ball or rod mills for further size reduction. Types of Mill Different types of mill are in operation e.g. rod or ball mills, so called depending on the steel based media placed internally to assist the grinding process. If no media is used i.e. the tumbling ore itself causes breakdown then the mill .

Ball Mills vs Rod Mills ... The term "overgrinding" is much used in conversation with mill men, but search of the literature indicates that a good definition does not exist. This is due probably to the absence of a satisfactory antonym. Selective and non-selective grinding are used here to compare products that have the same amount of the ...

the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application. The critical speed of a ball mill is calculated as 54.19 divided by the square root of the radius in feet. The rotational speed is defined as a percentage of the critical speed.

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". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Ball/Rod mill Literature . The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
