1. AL2O3 content: 70%, 92%,size 30-60mm
2. Ideal grinding media for ceramic
3. High bulk density,Anti-corrison, High Quality
Inert Alumina balls:
It is produced with the following technology: advanced spray drying granulation, dry type full automatic iso-static pressure process and high temperature roller kiln sintering technology.
Under the latest check technology, it is known as high quality product with high hardness, high density, high strength, good toughness and same structure inside and outside.
With its high efficiency and low wear lost, it is particularly fit for architectural pottery and fine chemcial industry for ball-milling glaze and raw materials. It can greatly improve production efficiency without adding ball mill equipments and other infrastruction facilities
