Ball Charge and Grinding Efficiency (22 replies) If the ball charge rate is between 812%, it will be SAG mill. If it is more than this, it will be ball mill. SAG Mill's effect is mainly crush the big ores and then use ball mill to grinding the small ores.

Live Chat>The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R=R. 0.

Live ChatOPTIMIZATION OF THE MAKEUP BALL CHARGE IN A GRINDING MILL 239 CONCLUSIONS The following conclusions may be drawn from the present work: ( 1 ) The joint solution of the grinding and ball wear models leads to the con struction of a graph (Fig. 1 ) showing the performance index (circuit ca pacity) versus the restriction (steel consumption by ball wear) for mon osized makeup ball charges

Live ChatBall Mill Charge (1 reply) The ball charge and ore charge volume is a variable, subject to what is the target for that operation. The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 4045%. If it is a grate discharge you will have more flexibility of the total charge.

Live ChatSimulation of a ball mill operating with a low ball charge level and a balanced ball size distribution . Simulação de moinho de bolas operado com baixo enchimento e com distribuição balanceada de bolas . Keywords: Grinding, simulation, optimization, ball mill. RESUMO.

Live Chat>mill diameter, mill length, grates openings, and pebble ports size the power equation is also function of all the operational variables selected for this study. The applied force is a function of the mass inside the mill and it is composed of balls, ore and water. The ball charge is a function of the bulk fraction of the SAG mill volume (Jb)

Live ChatBall mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in

Live Chat>Optimization of mill performance by using online ball and pulp measurements. In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency

Live ChatThe combination of a grinding circuit simulator with a model of ball wear in a grinding mill leads to a method to calculate, with a preselected accuracy, the makeup ball charge that optimizes the operation with respect to a given objective for the grinding process.
