Compound partition diaphragm for use in a ball mill
A partition diaphragm which divides a grinding chamber of a ball mill into several chambers is formed into a compound structure comprising a primary screen plate and a secondary screen plate, with the slit clearance of the secondary screen plate being smaller than that of the prior art while avoiding the occurrence of blinding. The secondary screen …

The toroidal region of high velocity fluid that rotates in the outer part of the chamber (green ring in the velocity maps of Fig. 11) is pushed towards the mill walls when the chamber radius is decreased, indicating that the rapid flow moving near nozzles is influenced by the spiral jet mill diameter and the gas motion tends to erode the crusts ...

However, it is reported that the secondary drying is insensitive to chamber pressures in the range of 0–0.2 Torr, but either diffusion in the solid or evaporation at the solid–vapor boundary is the rate-limiting step to mass transfer process for drying an amorphous solid, suggesting that relatively high chamber pressures (0.1–0.2 Torr ...

Analysis of the particle collision behavior in spiral jet milling
The fluid forms a vortex over a whole grinding chamber and rotates approximately axisymmetrically around the center of the grinding chamber. The velocity increases with approaching the center from the side wall of the grinding chamber. In contrast, the points where the fluid flows from the inlet nozzles cross each other cannot …
