Grinding Media & Lining Media Liner Wear Rate Modelling

 · 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 ...5.2 The Principle of Dimensional Homogeneity Re p Re m 25.3 998V 0. p 0 (0 0. 1 001) or V p 0. m/s 2.53 cm/s Ans. C Fp C Fm 1.14 or F p 7.31 10 7 N Ans. It would obviously be difficult to measure such a tiny drag force. Historically, the first person to write extensively about units and dimensional … · and, after applying the usual methods of dimensional analysis, this leads to. ... The relationship between rate of wear of the metal surfaces and the ball charge in the mill is shown by the data of Gross, plotted in Fig. 8.9. This curve is seen to be, very roughly, of the same form as that of Fig. 5.18, relation to the total surface produced.

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.The present analysis of the radial velocity and the square of spinnumber functions use some geometrical factors reported in the literature. The most important factor is the ratio between the mill ... · The analysis was based on the three-dimensional filming of the motion of balls in a model rotary mill (Powell and Nurick, b).
