The Bond Index conforming ball charge consists of: 43 x " balls. 67 x " balls. 10 x 1" balls. 71 x " balls. 94 x " balls. The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of grams.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

The cellulose fibres (2 g) were pretreated in a vibratory ball mill (Retsch CryoMill, Retsch , Germany) for 15 min at 25 Hz in a 50 mL vessel using five grinding balls (stainless steel) with a diameter of cm and one with a diameter of 1 cm to obtain fluffy fibres (this pretreatment only increased the initial reaction kinetics and is ...
Grinding tests were performed in a RETSCH centrifugal ball mill (S100). The grinding jar (500 ml) rotates in a horizontal plane and was charged with 106 balls ranging from to 10 mm diameter with a total ball load weighing g, grinding balls with different particle sizes being used to increase the grinding rate [17].
The extractive free sawdust was finely ballmilled in a Retsch S100 centrifugal ball mill with toluene (150 h). After this treatment, the milled wood was submitted to an extraction (4=24 h)
