The Study of Particles Size of CassavaStems to Effecting Fuel Pellet production

Abstract

         The objective of this study is in to investigate sizes of cassava stems passed through the screening sieve sizes of 3, 4, 5 and 6 mm can be summarized as follows. And study physical properties after chopping and pelleting

         The test of the cassava stems shredder showed that the capacity and percentage of shredding were 43.85 kg.h-1 and 64.79%, respectively, at a 6 mm screening sieve with a tendency to increase the sieve hole. After shredding. While the highest total density was 139.28 at 3 mm screening sieves, which tended to decrease as the sieve size increased. and the pile angle result tended to increase according to the sieve hole size, which was the maximum of 50.70° at the 6 mm screening sieve. and the highest modulus of fineness 2.45 mm and 4.65 mm respectively, at the 6 mm screening sieve, with a tendency to increase according to the sieve size.

   Biomass pellet machine testing revealed that the maximum compression capacity was 61.49 at a 5 mm screening sieve and the highest percentage of forming was 98.05% at a 4 mm screening sieve. Maximum 29.21° at a 6 mm screening sieve. The results of the study were the diameter and length of pellet fuel of the same size. It was found that the maximum fuel pellet weight was 0.96 g at the 4 mm screening sieve, the actual fuel density was 1323.76 at the 6 mm screening sieve, and the total fuel density was according to the industry standard. Solid biomass fuel pellets of all sizes and the durability that passed the standard was screening sieve size 3 and 4 mm, equal to 98.39 and 98.25 % respectively.
