A higher Blaine indicates higher fineness and vice versa. Lower than prescribed cement fineness indicates poor quality of the finished product resulting in more recycling and thereby increases the grinding cost further. After grinding, the cement is separated from the carrier gas (hot air) in the bag house.

Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.
Of course, customers can adjust the fineness range according to their own requirements. As for the output, the output of the ultra-fine mill ranges from 0.7-8t/h, which depends on the model of the mill. set.
