High-Energy Ball Milling - an overview | ScienceDirect Topics
High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods

Ball Mill Loading - Dry Milling - Paul O Abbe
The starting point for ball mill media and solids charging generally starts 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 10%-15% above the ball charge for total of 23% .

Ball Mill Charge - Metallurgist & Mineral Processing Engineer
The ball charge is determined by the operator targeting the balance between grind and throughput, the higher the ball charge the more aggressive the milling becom With softer oxide ores lower ball charges are usual however the harder sulphides does need more media energies to meet the P80 target and an acceptable throughput
