Grinding balls with diameter 3 mm and smaller must be weighed out. The above table provides you with the necessary weight to be included per grinding bowl.
The quantity of grinding balls can be reduced by up to 15%; however, increased wear should be expected in this case. The specified number/mass of balls per bowl is the minimum quantity; depending on the material behaviour, it may be necessary to increase this.
In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, larger or heavier balls with a higher density can be used, e.g. tungsten carbide balls in a steel bowl or zirconium oxide balls in a silicon nitride bowl.
