- Model A&B Series - Hammer Mill Grinders


Selecting the right method of animal feed grinding is a critical decision in that it directly affects the blendability, digestibility and performance of your livestock greatly. The ideal grind necessary is determined by feed size, feed rate, operating conditions and desired product output for feed processing. Stedman offers two types of hammer mill grinders that transform the consistency of soft and rough animal feeds by using the pulverizing technique of a hammer mill grinder to produce a finished particle.

What is the difference between A and B Series Grinders?

'Up running,' or the A Series, Stedman Hammer Mills provide multiple size reduction stages for friable animal feed materials and 'down running,' or B Series Hammer Mills, are most suitable for fibrous animal feed materials due to high concentration of shearing actions within the unit.

Type A “Up Running” Hammer Mill

This series uses perforated screens or grate bars for reducing soft to medium hard feed materials. The material to be reduced determines the rotor construction of a Stedman Hammer Mill. The rotors used in the Type A hammer mills are adjustable to compensate for wear.

  • Shattering by revolving hammers
  • Impaction against housing liners
  • Grinding on the adjustable grinding plate
  • Shearing by the grate bars or screen 

Type B “Down Running” Hammer Mill

This series utilizes specially designed heavy reversible hammers, working in conjunction with Stedman’s adjustable breaker plate enables the Hammer Mill to produce exceptionally uniform product with the lowest possible maintenance.
