Alumina Grinding Mill & Media

High density Alumina lining mill & media can be used widely in the mineral processing, ceramic, white cement, abrasive material and paint industry. For general purpose grinding, we supplies two materials : A90, which offers superior density and abrasion resistance, and A995 has recommended for the highest purity media in critical environments where corrosives may attack the media, or media induced product contamination is a concern.

The ball shape is preferred for converting large-size feed material into finely ground products. Natural shape is best when there's little requirement for primary size reduction and it's an extremely efficient shape for dispersing solid into a vehicle. The rod media are particularly effective in vibration mills and should be used when a uniformly fine product of limited size range is required.

Size requirements differ with the material being ground or dispersed the feed size and finish size. Generally, the largest media selected should be at least 5 time larger than the largest feed particle.

Maintain the media charge at48%~55% of total mill volume in batch-type mills and 38%~42% in continuous mills.

We recommends 55% to 65% of critical mill speed for optimum grinding performance.

Dry grinding requires faster mill speeds than wet grinding
