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/v U 1,5. 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.
Over-size particles, not easily broken, drop through the mill and may be re-cycled or discarded. Thus foreign materials, such as metal and stones, are discharged before they are forced through the screen causing damage. Fig. 1 Hammer Mill. 2.2 Attrition Mills.
