An investigation of mixtures of grinding media of different shapes is worth it to understand how they affect the milling kinetics. Our hypothesis is that the volume of grinding zones can be increased when there is an optimal mixture of two grinding media with different shapes and, therefore the milling kinetics will be improved.

به خواندن ادامه دهیدAbstract The effect of grinding media on milling kinetics has been generally studied using one media shape. However, very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts, the volume of grinding zones can be efficiently increased when there is an optimal mixture of two or more grinding media with different shapes ...
