Ball milling is a simple but effective method that transfers the kinetic energy of moving balls to the solid substance (Lyu et al., 2017). Recently, ball milling has been frequently applied in the filler production to enhance the fillerrubber interaction through refining the particle size (Beckert et al., 2014; Muttalib and Othman, 2016; Xu et ...

A ball mill is simply a container that is filled with pebbles (either of porcelain or stones Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, lowspeed ...
