500ml Highly Polished Tungsten Carbide Grinding Jar with Lid
Grinding jars
The selection of the right grinding jar and the correct filling level has a big impact on the grinding result. According to the application you have to select the correct material and amount/volume for the grinding jar and the grinding balls.
A jar filling should consist of about 1/3 sample and 1/3 ball charge. The remaining third is the free jar volume that is necessary for the movement of the balls. The following table provides recommendations.
Selection guide for grinding jars and balls
We recommend to select always grinding jars and balls built from the same material
