The invention relates to a system and method for changing liners of a mill, the configuration of which allows the automated robotic manipulation of liners of mills for ore grinding in comminution processes. The configuration and operation of the system allows the task of manipulation to be improved, having a greater degree of freedom and/or flexibility in its movements, thereby providing a greater degree of certainty and efficiency to the method and thus optimising the time that the mill is halted for maintenance, and also preventing the risks to which maintenance staff may be exposed. The system comprises at least one support structure, at least one system for supplying and moving liners, at least one robotic manipulator system for manipulating the liners, at least one liner manipulation tool, at least one artificial vision system, and at least one control system.

A method for preparing nanometer MAX phase ceramic powder or slurry having a laminated structure by means of ball milling and regulating the oxygen content of the powder. Micron-sized MAX phase ceramic coarse powder is adopted as a raw material, during ball milling, a gas or a liquid-state gas having a special effect is introduced into a ball milling tank, and by means of multi-dimensional functions and regulation such as ball milling parameters and gas reaction, the nanometer laminated MAX phase ceramic powder or the slurry containing the component is obtained. The surface components and the activated state of the powder are regulated while the particle size adjustment control of the powder is realized.
