Jun 25, 2008 An attempt has been made to develop correlation for the performance of the ball mill by correlating these variables with the grindability on the basis of dimensional analysis approach as well as fractional factorial design method. It is observed that these parameters influence the performance of the ball mill significantly.

A dimensional analysis of the ball mill process is carried out through the Buckingham-Pi method. The dimensionless quantities identified are discussed and used in order to suggest scaling criteria for ball mills. The flowability and the particle size distribution of an alumina powder ground in laboratory ball mills of various dimensions are ...

The number of lifters of mill shell liners, mill rotation speed, and filling percentage of grinding media are three of the most important parameters influencing the charge behavior and the trajectory of ball motion inside the SAG mills, and consequently, their performance. In this paper, the milling operation of pilot-scale SAG mills using the discrete element method (DEM) is investigated.

Preliminary Analysis The preliminary or one-dimensional analysis of a propulsor is a very important step. It is from this step that the designer selects the type of propulsor which is to be employed and matches its performance param- eters to those of the vehicle in question. In order to conduct this step,

Through the research of the paper, the power of the ball mill increases with the increase of the friction angle. The higher the energy is, the less the number of impact is, the number of impact on the liner with the lower friction angle will reduce quickly. ...
