ball mill process variables

Variables in Ball Mill Operation Paul O. Abbe®

In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables.

Ball Mill an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Comparative Study on Improving the Ball Mill Process

2021-2-19 · The ball mill process parameters discussed in this study are ball to powder weight ratio, ball mill working capacity and ball mill speed. As Taguchi array, also known as orthogonal array design, adds a new dimension to conventional experimental design, therefore, Orthogonal array (L9) was carefully chosen for experimental design to understand the effects of the ball mill process factors [ 16 ].
