A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.

The ball mill is a common mineral processing equipment in the industry. Its working principle of the cylinder and the lining plate of the cylinder work together to raise a part of the steel ball to a certain height, and the free fall movement generates impact force, which hits the material in the cylinder and completes the grinding operation. .

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 or by weight based on product's bulk density.

 · Ball mill is the core equipment in the process of cement combined grinding. Load of ball mill is an important index to characterize the running state of ball mill. Cement particle size is a key index to determine the quality of cement products. In this paper, the load of ball mill and the particle size of cement are studied. In view of their strong coupling and uncertainty, it is …
