Product fineness during grinding in stirred media mills is mainly influenced by the specific energy input, stress transferred colliding and frequency. The from collisions heterogeneously distributed mills. Herein, order to characterize distribution local collision frequencies, motion was calculated using discrete element method (DEM) simulations coupled with computational fluid dynamics (CFD). ...

Grinding aids are commonly used in grinding to disperse the material system effectively and improve performance. Most of time, different with varying dosages tested laboratory conditions by trial error. A simple methodology is required compare results batch milling. In this study, utilization modelling approach comparing effect aid types were aimed. order achieve this, an experimental program h...

BLACK Luffa sponge, derived from dried fruits of Luffa aegyptiaca Mill. (Sponge gourd, Hindi – Ghiya tori), could be a suitable matrix for tissue culture in aseptic liquid culture media. To test this, the response of aroid Philodendron ‘Xanadu’ Hort., an exquisite indoor-ornamental with its beautiful leaves and tangled aerial roots, was studied in vitro by Gangopadhyay and others. A study on in...

This work addresses the model-based optimization of the operation procedure of an emulsification process using a stirred vessel in combination with a colloid mill and a recycle. The computation of input trajectories (i.e. the stirrer and rotor speed in time), for reaching a certain predefined drop size distribution in minimal time, is studied. It is argued that gradient based optimization techn...
