Demonstration of the Feasibility of Predicting the Flow of

202028 · Understanding and predicting the flow of bulk pharmaceutical materials could be key in enabling pharmaceutical manufacturing by continuous direct compression (CDC). This study examines whether by taking powder and bulk measurements and using statistical modelling it would be possible to predict the flow of a range of materials likely to be used in CDC.

It is especially suitable for grinding to slag and cement clinker with worse grind ability and can satisfy the demand of high specific surface area of slag powder. It can grind slag thin to 430m<2>/kg in one time while it is provided with low flow speed of grinding material small equipment wear and long service life.

Improvement of process parameters and evaluation of

 · The current ball mill process results in a broad multimodal but not in a bimodal particle size distribution which confirms previous findings 9 11 . Due to the lower package density this can be seen as a disadvantage when compared to roller refiners 7 9 30 . On the other hand there are less fine particles and specific surface.
