Improving particle size distribution and flow properties

Sep 17, 2013 Grinding can generate varying particle size distributions (PSD), which again influence flow parameters. The latter are very important for downstream processing as well as mouthfeel and consumer acceptance of the final product. The objective of the work was to influence and control PSD and flow properties of ball mill chocolate

Silicon Powder Properties Produced in a Planetary Ball

Jan 15, 2020 Mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. In this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead size (20 mm, 2 mm, 0.25 mm) and
