Alumina Ceramic Balls as Grinding Media
Alumina grinding balls with raw materials calcined alumina is mainly applied in wet grinding mill of glaze milling , tile body milling etc. Wet ball mill smashes materials mainly through grinding instead of impacting, so good proportion of using ceramic balls is required to calculate exactly ,Chemshun Ceramics have great capabilities of calculating 92% 95% Al2O3 grinding balls proportion quantity , size according to customer's offered information including : granularity of raw materials , diameter and rotary speed of ball mill . too many alumina balls filled in the ball mill will bring mill bricks abrasion damage more quickly .
