Alumina Ceramic Grinding Balls
Introduction
Aluminum Bead is superior to natural pebbles and conventional grinding media and is the best option for grinding processing in many industries because to its high density, regular shape, ease of sorting, high crushing efficiency, and low cost.
Application
Aluminum Bead is frequently used as a grinding medium in the mining, cement, coating, color, and ceramics industries as well as the chemical, pharmaceutical, and coating industries. The ball mill with high alumina ceramic balls is superior to natural pebbles and conventional grinding media and is the best option for grinding processing in many industries because to its high density, regular shape, ease of sorting, high crushing efficiency, and low cost.
Advantages
Second only to diamond in hardness
Low abrasion, high grinding efficiency
Shape rules
Corrosion resistance
No pollution
Long service life
