data of diameters of the ball in a mill

THE OPTIMAL BALL DIAMETER IN A MILL

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Chart of End Mill Diameter Sizes

End Mill Sizes Many people have asked that we create a chart showing all of the end mill diameters. So we have done that, and want to make all of our customers aware. You can find this in the tab called "Technical Info" and the link "End Mill Sizes". As you view the chart you will notice some sizes are linked also. This will take you to a page where all of that diameter's end mills are listed.

Ball Mill an overview ScienceDirect Topics

The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Ball mill Wikipedia

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.
