Grindability Ball mil Dimensional Analysis approach and Fractional Factorial DesignVarious parameters viz particle size number of balls time of grinding particle density and speed of the ball mill rpm have been considered for the present work to determine the performance of the ball mill
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 The performance of a ball mill is measured with reference to the quantity of undersize or fines
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
parameter of ball mill Correlations for the grindability of the ball mill as a parameters on the performance of a ball mill The parameters studied in time High energy ball milling process for nanomaterial Dimensional analysis and ball mill performance Products parameters effecting cement ball mill performance drying cement
Nov 01 2004nbsp018332The analysis was based on the threedimensional filming of the motion of balls in a model rotary mill Powell and Nurick 1996b These definitions are considered by the authors to be useful and consistent and have been the basis for the ongoing analysis of the motion of grinding media in mills

Mar 01 2011nbsp018332To measure throwing performance we used a square of 12151 m at about eye level 175 m high and instructed the participants to throw the ball with a maximal ball velocity to the center of the target Horizontal distance between the ball and the target at ball release was about 8 m except for the standing and pivot throw about 7 m
increased performance in computers in recent years it on ball motion in mills using the discrete element method has been proposed by Mishra et al2 and Yanagi et al3 So far reports on analyses simulating threedimensional analysis and complex liner shapes4 5and research on mill power consumption 6 7 have been published

73 DIMENSIONAL ANALYSIS AND SIMILARITY In most expp y periments to save time and money tests are performed on a geometrically scaled model rather than on the fullscale prototype In such cases care must be taken to properly scale the results We introduce here a powerful technique called dimensional analysis
However in this situation the ball mill has to supply this energy and it has a different higher work index than the crusher ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction Hence from equation 7 to crush to the ball mill
