The Cement CGB (Abbr. Ceramic Grinding Ball) is made of high purity alumina.The alumina based products feature high temperature tolerance,hard wear resistance and high performance in anti-erosion.It has the excellent grinding efficiency in ball mill and cement industry.
TOPNEWER, as a supplier of CGB, provides high-quality CGB and comprehensive solutions for high efficiency grinding of ball mills.
The typical properties of cement CGB are:
- High density, 3.6g/cm3.
- Ultrahigh hardness, Mohs scale 9, second only to Diamond in mineral.
- Good corrosion resistance, resistant to most acids and Alkalis.
- Excellent wear resistance, very low wear loss, less than15‰.
- Uniform and regular in shape.
Chemical and Physical of properties
|Chemical Properties||Typical Value|
|Water absorption rate（％）||0.01|
|Bulk density (g/cm3 )||≥3.60|

Industrial test Standard reference:
GB/T 2997 – 2000 for bulk density,porosity.
GB/T 6900.9 – 2006 for alumina purity
GB/T 6900.10 –2006 for chemical composition
GB/T 8488.5-2001 for water absorption
Criterion of Fracture Strength
|Diameter (MM)||Pressed CGB||Rolled CGB|
|As CGB is normally used in the 2nd or 3rd chamber,the application diameter is in thesmall range.|
|For the time being,2 shaping methods are adopted to produce CGB.One is by Isostatic press machine,so called pressed CGB; Another is made by rolling machine, so calledrolled CGB.|
25kg double plastic bags or as request.
