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.
Normally, grinding bowls and balls of the same material are used. In principle, the grinding bowl materials must be harder than the material to be ground. Important: Pay attention to the specified useful capacity as this is not identical to the bowl volume!
It may also be useful to work here with grinding balls ≤ 3 mm diameter. We have not listed these here because we would like to advise you regarding your application. Please contact Mr. Gerber, email: gerber(at)fritsch.de
