Hammer Mill Constant Torque Or Variable Torque 4

Hauhouot et al., (1997) mentioned that a hammer mill with 16 hammers, a 4.58 mm screen, and an operating speed of 3600 rpm was more effective at grinding a mixture of 1.24 mm (minor diameter) cheat seed, chaff, and straw than a roller mill set with a roller gap greater than 0.1mm.
