  • Influence of Hammer Mill Screen Size on Processing

      The effect of hammer mill screen size on processing parameters and particle size of milled sorghum were examined Sorghum grains were ground through two levels of hammer mill screen size: 2 mm and 6 mm and then subsequently fractionated by size on a set of eight sieves ranging from 0045 mm to 28 mmhammer mill screen size (2 and 6mm) on processing parameters: production output, energy consumption, average particle size (dgw), geometric standard deviation (sgw) and to characterize the influence of particle size, after segregation by sieving, on starch enrichment and bulk density The results of this study show thatThe Effect of Hammer Mill Screen Size on Processing Table 1 Effect of hammer mill screen size (2 mm and 6 mm) on processing parameters of milled sorghum (data were presented as means ± standard deviation) Hammer mill Processing parameters Energy Production Temperature screen size j § (Wh/kg) (kg/min) (°C) 2mm 0525b±002 183a±005 140" ± 14 133b ±015 428" ± 13Influence of Hammer Mill Screen Size on Processing The effect of hammer mill screen size on processing parameters and particle size of milled sorghum were examined Sorghum grains were ground through two levels of hammer mill screen size: 2 mm and 6 mm and then subsequently fractionated by size on a set of eight sieves ranging from 0045 mm to 28 mm The objective of this experiment were: i) to characterize the influence of hammer mill screen Influence of hammer mill screen size on processing A larger screen size of the hammer mill (127 mm) and higher moisture content of 18 % (wb) increased the briquetting energy consumption for both the woody and herbaceous biomass Larger hammer mill screen size (1905 mm) and moisture content of 15 % (wb) resulted in lower density and durability rating of the briquettes producedEffect of Moisture Content and Hammer Mill Screen Size on

  • Influence of moisture content and hammer mill screen size
