An improved free swinging hammer mill hammer design is disclosed and described for comminution of materials such as grain and refuse. The hammer design of the present art is adaptable to most hammer mill or grinders having free swinging systems. The improved hammermill hammer may incorporate multiple comminution edges for increased comminution efficiencies.

Our paper presents the hammer mill working process optimization problem destined for milling energetic biomass (MiscanthusGiganteus and Salix Viminalis). For the study, functional and constructive parameters of the hammer mill were taken into consideration in order to reduce the specific energy consumption. The energy consumption dependency on the mill rotor spinning frequency and on the sieve ...
