Cement Alumina Pressed Ball

Cement alumina pressed ball is made of high-quality materials and advanced cold isostatic pressing technology to form high-quality grinding media after high-temperature calcined.

It is normally used in the 2nd or 3rd chamber,the application diameter is in the small range.

Cement alumina pressed ball is made of high-quality materials and advanced cold isostatic pressing technology to form high-quality grinding media after high-temperature calcined.

Topnewer has two and eight cold isostatic pressing machines for 1550 °C high temperature tunnel kilns, which ensures the stable quality of alumina balls.

 

The typical properties of cement alumina pressed ball are:

1. Super hardness

2. High density

3. Low wear loss

4. Regular shape

5. Good corrosion-resistance
