On Predicting Roller Milling Performance IV: Effect of ...

First Break milling of both hard and soft wheat samples under a S-S disposition gave an even distribution of particle sizes over the range 250–2000 μm, which could be described by linear breakage functions. The effect of changing roll gap was to change the slope of the line i.e. to change the balance between small and large particles, with ...

Mechanical Milling for Pharmaceuticals - Catalent

Mechanical milling with a pin design can provide a smaller particle size than a hammer mill. Conical Mill– This mill can be used to reduce the size of material in a uniform manner. It is an alternative to the hammer mill or other forms of pharmaceutical grinding mills. Particle size reduction takes place via a rotating impeller.
