A preliminary simulation model for fine grinding in high speed hammer mills
Table 2 gives the tip velocity and assumed dimensions of the high speed hammer mill and other assumed parameters, plus the predicted mill power and rate of mass impact. Table 3 gives the results, as product size distributions for a feed of 0.10 kg/s, with and without allowing for damage accumulation and internal classification (Fig. 4).

Full Circle Screen Hammer Mills
The high-speed 24 Series Circ-U-Flow hammer mill is designed for mid-range production grinding of a variety of products. The nearly full circle screen translates to a large screen open area and thus the highest possible production rates on materials that do not require initial grinding against a breaker plate.
