The optimal ball diameter in a mill

And with the decreased grain size, the necessary ball size also decreases (olejnik, 2010; 2011). for each grain size there is an optimal ball size (trumic et. al., 2007). the bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. in both

Speeding up your organic synthesis with ball mills

Apr 07, 2015· investigation of the technological parameters reveals that the type of ball mill, whether it is a mixer ball mill or planetary ball mill, does not influence the outcome of the reaction. however, variables such as the size and count of the grinding balls, the milling material and the filling degree of the grinding bowls play an important role.
