Ball Mills work by employing various types of media (either steel, ceramic or lead balls) to crush the material in the barrel. To use the Mill, the material to be ground is loaded into the barrel which contains grinding media. As the barrel rotates, the material is caught between the individual grinding media balls which mix and crush the ...

The Operating Principal. P ulverization takes place in the central chamber of the MicronMaster® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the highvelocity collisions between particles of the process material itself.
