Ball Mill Motor Power Draw Sizing and Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

Electromechanical Dynamic Behaviour and Start-Up ...

The evaluation of the start-up process of the ball mill aims to ensure successful start-up without the drive or clutch protection device that causes the mill to stop. Considering this condition, the start-up process is made as short as possible to reduce friction disc wear and heat generation. Therefore, the quantitative evaluation indexes of the start-up process of the ball mill can be set as ...

Variables in Ball Mill Operation Paul O. Abbe®

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it’s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent ...
