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.
