Sep 29, 2015 Air jet milling is found to be the most effective in reducing particle size from a d 90 of 37 m to 2.9 m compared to planetary ball milling (30.2 m) and single ball milling (10.5 m). XRD and TEM studies confirm that the planetary ball mill causes phase transformation to the less desired -Alumina resulting in a notable decrease in surface area from 136.6 m 2 /g to 82.5 m 2 /g as measured

Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Purpose Rosuvastatin calcium (ROSCa) nanoparticles were fabricated by planetary ball mill to enhance ROSCa dissolution rate and bioavailability. Methods Milling time factors (milling cycle time and number as well as pause time) were explored. The effect of different milling ball size, speed, and solid-to-solvent ratio were also studied using Box-Behnken factorial design.

Based on powder particle size and impact energy required, balls with size of 10 to 30 mm are normally used. If the size of the balls is too small, impact energy may be too low for alloying to take place. In order to increase impact energy without increasing the rotational speed, balls with high density such as tungsten balls may be employed.
