Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill. With this in mind, it is interesting to make a qualitative comparison of the ball size distributions which should be generated by 76 mm pearlitic carbon steel balls versus 76 mm martensitic ...

Ball mill | PyroData

Ball mill. 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.

There's something other than steel in the ball you have. Perhaps it's filled with something denser than steel? A 3" (diameter) sphere is ~231.67 cubic centimeters. Steel is ~8.05 g/cubic-centimeter, so that would be ~1864 grams, or 4.1 pounds. A solid lead ball 3" in diameter would weigh about 5.8 pounds, so even lead isn't that dense.

The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in the industry as the "angle of break." This angle can be between 40 to 65 degrees as measured from the horizontal. If the angle is too shallow, the media will not cascade much from one end to the other.
