Full Circle Hammer Mill

Stedman designs, develops, and delivers high-performing, long-lasting full circle hammer mills that provide a finer grind than standard hammer mills.

What is a Full Circle Hammer Mill?

Our standard hammer mill uses a rain of hammer blows to shatter, crush and disintegrate materials, usually rocks and minerals, upon impact. The size of the finished product depends on the openings in screens or grates; the number, size and type of hammers; the grinding plate setting; and the rotor speed.

Our full circle hammer mill incorporates a turbulence channel at the bottom of the rotor which interrupts the material flow before returning it to the path of the hammers. This unique design delivers a finished product with much smaller – usually medium to fine – particle size.

Stedman’s full circle hammer mill is perfect for a wide variety of industries where materials must be ground into a smaller particle size than a standard hammer mill.
