Abstract Talc powder samples were ground by three types of ball mill with different sample loadings, W, to investigate rate constants of the size reduction and structural change into the amorphous state. Ball mill simulation based on the particle element method was performed to calculate the impact energy of the balls, E i, during grinding. Each rate constant correlated with the specific ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
