High Alumina Grinding Ball Manufacturer
Application
Grinding Balls are are widely used in various manufacturing processes across industries like ceramics, enamel, glass, and chemical plants. Particularly in grinding processes, from fine to deep processing of even the thickest and hardest of materials. Thanks to its grinding efficiency and wear resistance (compared to ordinary ball stones or natural pebble alternatives), alumina ceramic balls are commonly used as the preferred grinding medium for ball mills, pot mills, vibration mills and many other grinding equipment.
