2. Numerical Methods. The mill geometry used for the simulations is based on the Hosokawa AS50 spiral jet mill. However, the geometry is based on an inhouse drawing made at the University of Leeds and shown in Figure 1 [28,29].The milling chamber is 50 mm in diameter and has four jets angled at 50 ∘ from the radius. A special feature of the AS50 is its classifier design.
