Hammermill

The rotor is spun at a high speed inside the drum while material is fed into a feed hopper.

The material is impacted by the hammer bars and is thereby shredded and expelled through screens in the drum of a selected size.

Large hammer mills used in automobile shredders may be driven by diesel or electric motors ranging from 2000 to over 5000 horsepower (1.5 - 3.7MW).

The screenless hammer mill uses air flow to separate small particles from larger ones.

[1][2][3] The water-powered trip hammer mills were powered by minor hill flowing stream that was connected to a large river beneath the high banks.
