Although the ball mill is significantly less efficient than the vertical roller mill in producing slag powder, the materials can be retained for a longer time in a ball mill, and the degree of structural disorder increases under mechanical force, producing more activation sites on the particle surface. Therefore, the hydration activity is higher.
