The ball load and pulp slurry detection is performed, on a mill section, at every revolution. Those raw signals are sent through a wireless link to a central unit where they are processed. The four angles are then computed and made available online to the customer supervision system via a standard OPC link or 4–20 mA electrical signals.

The radius and angle position of the mill charge centre of mass is commonly used for the ball mill dynamic model during start-up. This model considers that the mill load maintains its resting shape and that the mill is lifted to a certain angle depending on the mill speed and existing operating conditions during its rotation [ 3 ].

The gears of the ball mill drive experience an intense impact stress, which reduces the resource of their operation and the mill as a whole due to wear. The article presents research on developing rational parameters of involute gearing, aimed at increasing the loading capacity of the gear as well as reducing the overall dimensions, noise, and ...

The process has been optimised and its mechanism explored by CV measurements, radical trapping, and EPR spectroscopy. Control experiments identify the action of ball milling rather than mortar and pestle is necessary to realise the effective activation of manganese, which can then be used in either solution or a ball mill for subsequent reactions.

The dynamic analysis of the charge inside the ball was done using Discrete element, EDEM software which resulted in the time varying load applied on the drum. This load was then applied to the FE model using ANSYS software for dynamic analysis of the ball mill structure. The ball mill was modeled in Autodesk Inventor 17.
