Carbon Carbon Bond Formation In Ball Mill

Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the crosssection of the balls charged to the mill with this in mind it is interesting to make a qualitative comparison of the ball size distributions which should be generated by 76 mm pearlitic carbon steel balls versus 76 mm martensitic.Learn More
