Within these limits a rod mill is usually superior to and more efficient than a ball mill. The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or

Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large

Effect of ball size and powder loading on the milling efficiency of a laboratory scale wet ball mill. Salili et al. reported the importance of the small ball size and small mass ratio of powder to ball for the efficient ball mill, while only two sets of experimental data for these variables were provided. Thus, the optimization of ball size

Earlier work by Fuerstenau and Kapur on the comminution of quartz in a single particle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm.
