In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
The ball mills. It was expected a loss on mills performance as predicted by grinding tests, showed on Figure 8. Figure 8 Comparison to standard charge and balls scraps. Thankfully, the performance of the vertical mill was still better than the ball mills, which reinforces the use of this technology.

Media and Product Ball Mill Loading Guide. (Percentages are based on total volume of cylinder) NOTE With media load at 50 , voids are created equal to 20 of cylinder volume. These voids are filled when product is loaded into the mill. Mills can be loaded by volume.
Operation of the mill in automatic mode, reduction of specific energy consumption for grinding a unit weight of the solid material (by 5 to 30 depending on the type of the mill) as well asconsiderable increase of the grinding productivity of the mill. Keywords ball mill.
A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. The materials are ground by moving the container. Because the structure of ball mills is simple and it is easy to operate, and so they are widely used.
BALL MILL DRIVES, LOADED, WAVEFORM LEVELS, SEPTEMBER 1A 1B • Above is a plot of the waveform vibration levels at both the 1A 1B ball mills when loaded (acceleration). • Note how waveform levels at 1A ball mill are higher than that at 1B ball mill for every measurement and especially at points PIH PIA (pillow block, coupling end bearing).
2.1 Pengertian Ball Mill Ball mill merupakan salah satu jenis mesin penggiling yang berbentuk silinder yang berfungsi dan digunakan untuk menggiling material keras menjadi material yang sangat halus.
