Hammermill
A hammer mill is a mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of small hammers These machines have numerous industrial applications, including: • Ethanol plants (grains)• A farm machine, which mills grain into coarse flour to be fed to livestockHigh mass density for efficient storage and transportation; Flowability as a bulk granular solid; High aerobic stability to minimize mass and energy losses during Optimizing hammer mill performance through screen selection

The hammer mill is a power mill making use of a highspeed rotating disc, which is stationary to a number of hammer bars that move superficially by a centrifugal forceIt was observed that on the overall, the disk mill consumed the highest energy compared to the hammer mill Benue Yam specie recorded lesser energy consumption across the mills compared to Delta Yam specie, signifying appreciable characteristics In the hammer mill, the highest energy consumption was recorded in screen size 4 mm for Delta YamA Comparative Technique for Performance Evaluation of Hammer Mill
Modeling of maize breakage in hammer mills of different scales
In addition, Kwon et al [13] used a PBM to study the breakage characteristics of lowrank coal in a laboratory swing hammer mill The experimental results were used to fit the parameters of the breakage functions of the continuous steadystate hammer mill model developed by Austin et al [16]The objective of this study was to investigate the breakage characteristics of LRC by swing hammer mills for use in clean coal technology Generally, the appropriate range of particle size distribution for the brown coal upgrading process is 100–3,000 μm, and thus, the process considered in this work is designed for this rangeInvestigation of breakage characteristics of low rank coals in a
