1. Definition What is the PSD ? Particles in a sample of powder don't have all the same size.In order to characterize the solids for some applications where the size is an important parameter, it is necessary to measure the size of the population of the particles and describe which proportion of the sample corresponds to a given size (or range of size) : the distribution of particle size is ...

Ball milling can be done periodically or can be continuous process. The speed of the ball mill can be adjusted from low to high and so is the rotation and vibration. A ball mill should be made of porcelain or other very hard surface since the grinding takes place between the walls and balls and it requires maximum efficiency.

When the amount of ore in the mills was the same, no appreciable difference between batch and continuous open-circuit ball-mill grinding was found. This should be so, because the progression in particle size for the duration of a batch run would be expected to be the same as the progression from the feed to the discharge ends in a continuous run.
