Rod Mills, How Do They Work?

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Roll-Forming Guide . determination of suitability for the application by professionally qualified personnel. This can alter the working surface of the roll and result in panels with radii that are less „crisp‟ or precise. Roll wear is generally offset by reducing the roll gap on one or more stands.

This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process 1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a
