However, if ball mills are able to accommodate the requisite amounts of material for processing, laboratory mills are occasionally deployed in small-scale battery production pilot plants. In commercial-scale production processes, agitator bead mills, vibrating bead mills, or continuous horizontal axis bead mills are the most common-place machines.
Each ball mill works on the same basic principle: the concept being that sample materials are agitated with grinding balls inside a closed jar system. This agitation means that materials are frequently subjected to strong mixing and crushing forces. The apparent difference, which can be seen immediately, lies in the different ways the jars move.
In commercial-scale production processes, agitator bead mills, vibrating bead mills, or continuous horizontal axis bead mills are the most common-place machines. Yet, in Giga factories and large recycling plants, laboratory ball mills still play a primary role in quality control processes when preparing material samples for analysis.
A third and essential characteristic of a ball mill, which greatly influences the outcome of the milling process, is the mill’s power. This is usually determined by the application.
For this reason, heat generation is typically higher in planetary ball mills than it is in mixer mills. Irrespective of the type of ball mill used, if the temperature reaches too high a threshold, it may be necessary to reduce the speed of the mill or insert grinding breaks.
However, the impact intensity is not only dependent on the speed and the movement of the jars, but also on how the jars are filled. Friction is also a main factor when it comes to generating heat during the ball milling process. For this reason, heat generation is typically higher in planetary ball mills than it is in mixer mills.
