1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen. For example, 250ml agate ball mill jar, normally is matched with 250g mixed agate grinding balls.
Type of ball mill: • There is no fundamental restriction to the type of ball mill used for organic synthesis (planetary ball mill, mixer ball mill, vibration ball mill, .). • The scale of reaction determines the size and the type of ball mill. • Vessels for laboratory vibration ball mills are normally restricted to a volume of 50 cm3.

There is a class of grinding apparatus called "ball mills", and are manufactured by firms such as Spex Certiprep, Glen Mills, Inc., Retsch and other fine ball mill manufacturers. The concept of operation is easy enough to understand: Balls of a particular hardness are tumbled in a closed container to erode the size of the material being ground.
Scale‐up of power consumption in agitated ball mills. Herbert Weit, J. Schwedes. Published 1987. Engineering. Chemical Engineering Technology. Des essais experimentaux en l'absence de corps a broyer avec des fluides newtoniens sont effectues pour mettre en place des modeles de prediction de la consommation de broyeurs a boulets projetes.

12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.
Typically, the mixed KCl/NaCl (n(NaCl) = n(KCl) = 5 mmol) was used as a flux, and the mixture of Bi 2 O 3 (130 mg), BiOCl (67 mg), and Nb 2 O 5 (350 mg) (stoichiometric molar ratio of 3: 2: 1) was grinded in an agate ball mill for 4 h. The mixture was calcined at 750 °C for 60 min using a muffle furnace in a porcelain boat.
Agate ball mill The agate ball mill (planetarytype rotating machine, Fritsch Pulverisette 5/4; Alfred Fritsch Co., Oberstein, Fritsch Japan Co., Ltd., Brazilian Agate) was cleaned by ultrasonic cleaner with MilliQ water for 15 minutes for three times and then by crushing the quartz sand for five times (mill rotation speed at 300 rpm for
