size reduction by ball mill

A specific energy-based size reduction model for batch ...

2015-1-1  A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10 –t n relationships and the mass-size balance approach.

Size Reduction. Size reduction can be accomplished in a variety of ways, based on the specific polysaccharide structure, such as thermal hydrolysis, chemical hydrolysis (acidic, alkaline, ozonolytic, and free radical), sonication and homogenization, by leading to a random size reduction often resulting in an increase in sample polydispersity.
