Effect of ball and feed particle size distribution on the milling efficiency of a ball mill: order to optimize the process across an entire circuit rather than individual units the output from a unit must be such that it gives result to an optimum system However, use of …

Ball Mill: Operating principles, components, Uses

The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form he fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition

High-energy ball milling technique for ZnO nanoparticles

The broad band with maximum intensity at 440 nm was found to shift to the higher wavelength region and become more prominent at the smallest particle size (30 nm) This shift in band position resulted in a change in color of the samples The initial color of the sample was white, but the color of the final product became green The band at 384 nm is the UV near-band edge emission

Feed Size VS Ball Size - Grinding & Classification

A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semi-self locking taper One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill A f80 = 6 mm would need a ball size of 75 mm
