H-Series™ Impact Mills

The Stedman H-Series multi cage mill is best at pulverizing, grinding, crushing and mixing abrasive and non-abrasive materials – wet, sticky or dry. H-Series Models work more efficiently than other types of pulverizer machines and provides a finer, more uniform grind.

H-Series impact mills can handle up to 240 tons per hour and are reversible for extended wear life. The H-Series cage mill is engineered and constructed to operate at or near-peak efficiency longer, providing a greater return on capital investment over its life than competing equipment.

Each H-Series Impact Mill housing can accommodate two-, four-, or six-row cage assemblies. This versatility is further enhanced by the capability to vary the number of pins in each row, to vary the rotational speed of each cage in relation to the other(s), and to change the relative direction of rotation of the cages.
