What Are the Differences between Dry and Wet Type Ball Mill?

The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform. The wet ball milling can not only grind agglomerate into fine particles, but ...

Ball Mill Loading

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

Making dark aluminum powder

As far as i know, the only kind of powder we can make from (ball)milling metals is "flake". The main issue i see is the particle size. Stuff tends to clump together the way we mill it. Also, adding charcoal to aluminum isn't how they make "dark aluminum powder" but it just might prevent some of the clumping action.
