Crushing and Grinding Optimization• 2003, D50 = 15-35 µm• 2006, D50 = 18-24 µm• 2013, D50 = 16-19 µm• 2014, D50= 17-19 µm
In 2012, seasonal cyclic behavior of PSD wasnoted and a customer/AVEKA DMAIC initiated

AVEKA

DMAIC Results and Questions• PSD results (D50 =15-35 µm →16-19 µm) realized byadding proprietary grinding aid• This proprietary addition not sufficient for total PSDcontrol• Control of ball mill temperature as critical as proprietary
addition
