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 The wood chips were successively ground in a hammer mill using screen sizes of 25.4, 10, 6.4, and 3.2 mm. The input power and the flow of material into the hammer mill were recorded continuously.(PDF) Development of size reduction equations for

Austin A preliminary simulation model for fine grinding in high speed hammer The highest corn size-reduction productivity using hammer mill was 113 kg h −1 with a screen hole diameter of 6 mm, rotor speeds of 1440 rpm and feeding rates of 120 kg h −1 recorded by Ibrahim et al. 2019. Beaters were made of heat-treated high carbon-steel to resist abrasion and distortion and to improve the overall performance.Modified and improved performance of local hammermill

An agricultural hammermill achieves fine grind at practical production rates. Hammer tip speeds of 7620m/min are provided at 1800 rpm by providing hammers (140) of sufficient length to provide a tip path diameter of approximately 1.37m. In order to avoid excessive centrifugal stresses on the hammer rotor and components, hammers are tapered to a hammer mill, producing maize flour of acceptable quality. These mills are in widespread use in rural parts of the world in areas where no electricity grid is available. Diesel-powered grain mills are limited to areas with access to fuel and spare parts.
