Grinding in Ball Mills Modeling and Process Control

An important characteristic of an industrial ball mill is its production capacity which is measured in tons of production per hour The production capacity depends 53 on mill dimensions the type of the mill (overflow or grate discharge) the speed of rotation the mill loading the final product size required from a given feed size (coefficient of reduction) the work index of the material

Vibration characteristics of an operating ball mill

A ball mill which is used to finely grind materials causes high levels of vibration and sound during grinding operations The vibration and sound of mills provide significant information about the internal conditions and can be used to estimate the status of the ground material We developed a simulation model for the vibration of a mill wall to better understand the relationship between the
