When grinding spices, the importance of a consistent, precise finished particle size cannot be overstated. The key factor in determining finished particle size is the screen covering the mill’s discharge opening.
Since the output frequency of the cycloconverter is derived from the main frequency, it must be lower than the system frequency. In practice the output frequency can be continuously varied from zero to about 50 percent of the system frequency. For GMD applications the operational output frequency is typically from 0.3 Hz up to about 6 Hz (Fig. 7).
