Abstract. The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.

Wet ball milling for 120 min produced smooth, creamy slurries. The resultant products were hotpressed at 180 °C and exhibited a plasticlike glossy surface and a high Young's modulus ( GPa), which was attributed to an increased bonding area. However, hydrogen bond formation occurs more predominantly during wood molding than ...
