Aggregate Hammers: Heavy-Duty for High-Abrasive Environments

hammer-01A recent Unicast innovation on typical Aggregate Hammer design resulted in a wear life improvement of 350% on the hammers in a Penn 7620 hammer mill from 26 weeks to 22 months. The design innovation involved taking wear material from the neck area and moving it to the impact surface. This redesign improved the heat-treat capability of this alloy to eliminate elongation and cracking. Further, weight was reduced by 13%. Download the World Cement article here.
