01-04-2016 0183 32 It is also evident from Fig 8c that in comparison with WC balls, Si 3 N 4 balls have a more negative effect on the milling efficiency at high BPR n valu The event stems from the weight difference between the two types of balls with the explanation that when a large volume of the milling vial is filled, the lighter Si 3 N 4 balls lose their kinetic energy more quickly than WC on...

For ball milling, you can assume a porosity of about 035 to 040 the volume of space between the balls and you can normally assume the pulp surface level is equal to the ball charge surface level So do a crash-stop and measure the volumetric filling of the charge, then multiply that volume by ,...
