Costea et al. developeda fuzzy logicbased control architecture in which the ball mill grinding process was considered as a single input and single output system (SISO) and the total feed into the mill was maintained by manipulating fresh feed flow. However, in reality the process considered here is a multiinput and multioutput (MIMO) system ...

The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the mass loss, as influenced by three basic wear ...

A mechanical ball milling method for ultrafast synthesis of a nickelbased metal organic framework (NiMOF) has been proposed. The NiMOF was successfully synthesized in merely one minute without any solvent, additives, or preliminary preparation. The effect of milling time, mechanofrequency, type of assistant liquid, and amount of assistant water were systematically explored.
