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 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 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
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
The B series grinder 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.
