How to use ceramic grinding ball in ball mill of

When ball mill cement grinding system is used in steel ball and steel forging, it is a common operation habit to "add material after starting empty grinding and stop grinding after discharging empty material". However, using ceramic grinding balls, these habits become the most common "killer" of "broken balls". The collision and friction between porcelain ball and steel lining plate will produce numerous micro-cracks, which will accelerate the expansion of cracks and finally lead to grinding ...
