Industrial Hammer Mill Grinders

The ideal grinder necessary is determined by feed size, feed rate, operating conditions and desired product output for processing. Stedman offers two types of industrial hammer mill grinders - Type A "Up Running" Hammer Mills and Type B "Down Running" Hammer Mills - that transform the consistency of soft and rough materials by using the pulverizing technique of a hammer mill grinder to produce a finished particle.

What is the difference between A and B Series Industrial Hammer Mill Grinders?

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

Type A “Up Running” Hammer Mill Grinder

The A series grinder uses perforated screens or grate bars for reducing soft to medium hard 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 Grinder

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