Interaction Effect of Operating Parameters of Blade on Vermicompost Quality under Drum Condition

The curve blade, operational parameters and vermicompost physical properties are the key parameters come to pronouncement for breaking, churning and mixing clods condition. C, L and J curve blades was tested in the churning machine under drum condition for large, medium and small textured clods at vermicompost physical properties namely moisture content (15.24-35.48 % db.), bulk density (646 -732kg m-3) and crushing force (30 N). The performance results were analyzed in terms of mean mass diameter of vermicompost with the effects of three operating parameters namely moisture content % db, blade speed m s-1 and blade type. Experiments were designed by opstate software and statistically analyzed and evaluated by RBD method. The average values of vermicompost mean mass diameter were found to be minimum 4.31 mm with their optimum moisture content % db, blade speed m s-1 were found to be 25.42 %, 5.34 m s-1 and C-curve blade respectively.
