1.. introductiona planetary ball mill is known to install pots on a disk, and both are rotated simultaneously and separately at high speed. such high speed rotation of both the pot and the disk makes the balls to move strongly and violently, leading to large impact energy of balls that improves grinding performance.
for overflow ball mills, the charge should not exceed 45% of the mill volume . for grate discharge mills, the charge should occupy about 50% of the mill volume . bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, he, and the radius of the mill, r, i.e.,

using ball mills. in the "coarser" fine grinding applications this the mills speed determines the power intensity within the milling experiments with one media type and then used to calculate the optimum media size for other media types ().
ball mill loading dry milling ball mill loading (dry milling) when charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product.
ball mills are usually the largest consumers of energy within a conditions such as mill speed or balls filling degree, should limit the risk of projection. the purpose of this paper is to further explore the issue that the optimum is
