The range between 40 and 60 m/s is precisely of interest for operation of the special hammer mill, however. By means of tests, the factor may be determined to be: f = 0,4/vU1,5. A constant peripheral speed of 55 m/s for fine comminution and 40 m/s for coarse comminution applies, irrespective of equipment size, as a design criterion.
