In this study, we used a planetary ball millin laboratory scale. The powders dis-tribution, the balls distribution, and the wear were modeled using DEM. The simulations of dry mill were conducted by using a standard coefficient of restitu-tion of 0.3 and a friction coefficient of 0.75 (ball-ball and ball-liner collisions) [20].
in many situations it was 10:1, for effective ball milling conditions you can go up to 20:1. But efficiency of ball milling depends upon many factors like Ball dia, PCA used, Rotational speed

Types of ball mill: wet grinding ball mill, dry grinding ball mill, horizontal ball mill, vibration mill, large ball mill, coal mill, stone mill grinder, tumbling ball mill, etc. The ball mill barrel is filled with powder and milling media, the powder can reduce the ball’s falling impact, but if the power is too much that may cause balls to
There are basically two methods of producing nano-scale particles: the “Bottom-Up” technique involves synthesizing the particles from atoms and molecules. With the “Top-Down” method the particles are reduced to nanometer size by grinding. Suitable tools for this method are planetary ball mills, such as Retsch’s new PM-series grinders, which provide the necessary energy input.
Ball milling of graphite with appropriate stabilizers is another mode of exfoliation in liquid phase. 21 Graphite is ground under high sheer rates with millimeter-sized metal balls causing exfoliation to graphene (Fig. 2.5), under wet or dry conditions.

Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33; Dry Ball Mill = kg / kWh = 0.023A i 0.5; Replacement Ball Size. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media size. Azzaroni (1981) and Dunn (1989) recommended the use of the following expression for the size of the makeup media:

The optimization of processing plants is one of the main concerns in the mining industry, since the comminution stage, a fundamental operation, accounts for up to 70% of total energy consumption. The aim of this study was to determine the effects that ball size and mill speed exert on the milling kinetics over a wide range of particle sizes. This was done through dry milling and batch grinding

The composition of mill scale (MS) obtained from the hot rolled steel line was established with a wavelength dispersive X-ray fluorescence (XRF) spectrometer (AXS S8 Tiger, Bruker, Billerica, MA, USA). Previously, 10 g of MS were ground to a manageable fine grain size of about 4 µm using a Retsch PM 100 type ball mill, containing WC balls.
