ALUMINAS: 70% up to 99.99%
Aluminas are one of the most versatile medias used for grinding as it is available in a wide range of purities, sizes, shapes and formulations depending upon the type of mill and product being ground. It is also a very economical media with the combination of low price and long life. The high purity and precision grades are more costly.
Alumina Silicates are becoming a more popular category of media for small media milling as it offers longer life than silicas and lower cost than aluminas. It is excellent for use in industries requiring a high volume of media.
