What Are The Common Problems Of Alumina Ceramic Balls?

1. The main components and forming process of commonly used alumina ceramic balls:

The main chemical composition of alumina ceramic ball is Al2O3, accounting for about 92%, and 8% of modified and toughening materials such as zirconia

Its forming process is mainly divided into two categories: press forming and rolling forming, there are various specifications, roll forming is used for diameters below 20mm, and pressing is used for diameters above 20mm.

2. Physical properties of alumina ceramic balls:

The Mohs hardness of the alumina ceramic ball is 9.0, the Rockwell hardness is 80~83; the density is 3.6g/cm3, and the bulk density is 2.2t/m3.

3. What technological processes are suitable for ceramic balls used in cement grinding systems:

Ceramic balls are suitable for various technological processes of dry cement final grinding ball mill system, especially the roller press-ball mill combined grinding system, which requires the average particle size of the grinding material to be less than 1mm; other cement grinding open-circuit or closed-circuit ball mills Ceramic balls can be used instead of steel balls (steel forging).

4. Influence of the use of ceramic balls on the mill liner and partition board

The density of the ceramic ball is 3.6g/cm3, which is nearly half lighter than the steel ball, so it has less impact and wear on the mill liner, partition board, activation ring, etc. Extended life.

5. How to adjust the grinding ball in the ball mill after using the ceramic ball.

Under the current process conditions, ceramic balls are used in cement grinding, mainly in the tail bin of the mill, which plays a role in grinding, instead of steel balls or steel segments. After replacing the ceramic balls, the filling rate of the tail tank should be increased by about 10%, and the loading capacity should be about 60% of the loading capacity of the original steel balls or steel forgings. The loading capacity of the steel ball bin before the ceramic ball should be appropriately increased, generally by about 20%.
