Calculate and Select Ball Mill Ball Size for Optimum Grinding

Calculate and Select Ball Mill Ball Size for Optimum Grinding. Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the singlesized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.

The effect of ball size on mill performance ScienceDirect

EFFECT OF BALL DOETER Results of many tests suggest that the form of the S function for normal breakage in ball mills is St=Wa (5) It is consequently very convenient to have a more general fitting function which reduces to this for lower values of x, to the left of the maximum shown in Fig. 2.

EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe, light emitting diode, phototransistor and video photographs were used to

Effect of ball size and powder loading on the milling

Effect of ball size. The effect of ball size on the particle size reduction has been investigated first for varying rotation speed of the container. Percent passing and size distributions of the milled Al2O3 powder are shown in Fig. 1, Fig. 2, respectively, as a function of particle size for varying ball size.

How Ball Mill Ore Feed Size Affects Tonnage Capacity

Under the right operating conditions, high power rate crushing can bring mill feed size down to near 80% passing 7,000 microns and finer, which can be handled more efficiently by ball mills.

How can one select ball size in ball milling and how much

Popular Answers ( 1) If the quantity of charge is very less then milling balls will start to collide with each other and no milling will take place. Ball size depends on initial size of charge and ranges from 10mm150mm dia. For particular material and initial size the ball size must be optimized.
