In 1942, the idea of assessing the wear by marking some of the balls from the mill load was raised, carrying out the test in a batch ceramic mill. Later, in 1948, other researchers introduced marked balls in industrial mills [23] .

As the ball mill rotates, the steel balls in the cylinder rise up on the mill's inside surface and eventually tumble down to the bottom. The raw material is fed into the ball mill at the ends and the steel balls impacting together eventually grind the material into a powder, which is collected through slots at the centre of the mill.
