bearing balls are the component of a ball bearing that permit smooth, friction-free rotary motion. they are typically manufactured out of steel, but can also be made from other materials such as silicon nitride ceramic, plastic or even glass. steel bearing balls are easily the most common ball material, with tens of millions produced annually.
the grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the spe cific impact energy of the balls calculated from discrete element method simulation. this relationship was successfully used for the scale-up of a rocking ball mill, and the optimum design and
mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. in this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead size (20 mm, 2 mm, 0.25 mm) and rotational
6 size distribution 9 it is an important consideration because it affe cts the processing characteristics of the powder. 9 the distribution of a particle is given in terms of frequency-distribution plot (section 36.7). the maximum is called the mode size. other properties of metal powders that have an effect on their behavior in processing them are:
