Hammer mills use large rotating drums with protruding metal bars (, hammers) that impact the material at high veloc ity to shatter and tear material particles. Typically, the metal bars swing freely from the drum, but fixed hammers are also common in hammer mill designs. Hammer mills are recognized as technology capable

Among those styles, the functionality of a hammer mill remains basically the same: Material is fed into a grinding chamber. Contact with moving hammers, and interior mill components reduce the material's size. Material remains in the hammer mill's grinding chamber until it is able to pass through a screen or grate with certain size openings.

By the late 1980s and 1990s a new type of shredder was needed. The generic term "super sized shredder" is being applied to a series of machines with a hammer swing of approximately 120 inches in diameter, with about million foot pounds of energy generated. The internal width of the machines seems to be in the 104 to 110inch range.
