Discrete Event Simulation Design Optimization Ball Mills ABSTRACT High energy ball mills are used to grind powder material down to a particle size below one micron Up to now the detailed physical mechanisms of the grinding process inside the mill have not been fully understood Hence the design of these mills as well as

The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the specific impact energy of the balls calculated from Discrete Element Method simulation This relationship was successfully used for the scaleup of a rocking ball mill and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy

Ball mill is a 12 type of rotating drum mainly used for grinding and the particle motion in a ball mill is a major factor affecting its final 13 product However understanding of particle motion in ball mills based on the present measurement techniques is still 14 limited due to the very large scale and complexity of the particle system

Apr 01 1999 · Therefore the discrete element method is a suitable choice for modeling the internal dynamics of ball mill where balls and the mill shell are treated as geometrically inviolate elements The discrete element analysis starts with a mathematical representation of the entities

In the early 1990s the discrete element method DEM was used for the first time to simulate media motion in tumbling mills Although it has been over a quarter of a century since this tool was first used to predict media motion it has not yet reached maturity to be used in predicting product size distribution and throughput of tumbling mills

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

Abstract Based on the research on the grinding media motion in the ball mill the discrete equation of grinding media motion about ball mill is established and the motion regimes of grinding media is simulated using the discrete element method DEM with simplifying the contact model of grinding media and rock material

Keywords modeling discrete element method ball mills mechanistic 1 Introduction In spite of the development and increase in popularity of several other technologies such as vertical roller mills stirred media mills and highpressure grinding rolls ball mills still retain a significant part of their importance in

The Essa ball and rod mill range includes Essa BM Series Laboratory Ball Mills – ideal for producing finer particles Available in 63 L 123 L and 21 L barrel volumes Essa RM Series Laboratory Rod Mills – suitable for larger and more coarse materials Available in 78 L

1999 Analysis of Power Draw in Ball Mills by the Discrete Element Method Canadian Metallurgical Quarterly Vol 38 No 2 pp 133140

Discrete element method simulations of a 15scale laboratory ball mill are presented in this paper to study the influence of the contact parameters on the charge motion and the power draw The position density limit is introduced as an efficient mathematical tool to describe and to compare the macroscopic charge motion in different scenarios ia with different values of the contact parameters

Running a ball mill is quite noisy so it is a good idea to operate it in a closed room or basement Normal materials will take a couple of hours to mill but harder things like metals can take days or even weeks so be patient Uses Grind your own bird feed obviously dont use lead balls for this

Jun 20 2010 charge motions of the mill for different fill level cases are simulated with the discrete Both the results of the theoretical calculation and the 3D DEM simulation show the accumulated volume of the steel balls inside the mill Ball mills normally operate with an approximate ball charge of 30 Read more
