The Effect Of Hammermill Screen Hole Diameter And . 2019-6-26 speed is a function of hammermill diameter and motor speed it is necessary to have a variable frequency drive VFD on the hammermill motor to adjust tip speed. The VFD allows the operator to adjust hammer tip speed while requiring minimum idle time
Anderson 1994 stated that when drive speed and screen sie were kept constant the increased hammer-tip speed obtained from increased rotor diameter produced particles of smaller mean geometric sie. Particles produced using a hammer mill will generally be spherical in shape with a surface that appears polished
