To determine the weight of the required balls, the "calculated weight of
a ball" is multiplied by the "number" of balls required.
Example: A 10 ml zirconium oxide bowl is to be filled with 30 zirconium
oxide balls with a diameter of 5 mm.
Calculation: 0.37 g * 30 St = 11.1 g
11.1 g of grinding balls can be weighed and inserted in the grinding bowl,
thus avoiding the time required for counting the balls.
6.2 Filling the grinding bowl
NOTICE!
Fill a maximum of 1/2 the volume of the grinding bowl with
grinding balls and grinding stock.
Do not fail to comply with the following sequence:
1.
Place the grinding balls in the empty bowl.
2. Pour grinding stock onto the balls and possibly add liquid for wet
grinding.
All sealing surfaces must be absolutely clean to guarantee
impermeability, particularly during wet grinding. The best
cleaning method is to use standard fleece.
