A tumbling mill is a collective name for the generally known ball mills, rod mills, tube mills, pebble mills and autogeneous mills. For all these kinds of mills the mechanics can be dealt with together, there being no substantial difference in the grinding process. There are two kinds of grinding body movements: either they describe an

Apr 4, 2020. The name "ball" or "pebble" refers to the type of grinding media that is introduced into the mill. The media when combined with ores or other subtances accelerate particle size reduction by virtue of their impacting on the particles as the mill rotates. The grinding action is as described in our article about how grinding ...

A simple and costeffective circuit for a small mill that requires a fine grind is a singlestage SAG or AG mill (no secondary ball mill). The mill is closed with a hydrocyclone (just as a ball mill would be) and may include a pebble recirculation and/or crushing system. These tend to be inefficient, but the simplicity makes them
