Neem-based pesticides are well known to reduce agriculture pollution. It was earlier found that free flowing fine powder of whole dry neem fruits (called PNF-powder neem formulation) of size range 300 μm to 390 μm, i.e. (−44 + 60 mesh) was the optimumsize range. Azadirachtin which is a key ingredient of neem is quite stable in PNF. This article delineates material and energy balance to produce 1 tonne of PNF on a commercial level by using hammer mill. The particle size distribution models and classical energy consumption models were used to fit the experimental data generated by changing the hammer millscreen.

Abstract


Neem-based pesticides are well known to reduce agriculture pollution. It was earlier found that free flowing fine powder of whole dry neem fruits (called PNF-powder neem formulation) of size range 300 μm to 390 μm, i.e. (−44 + 60 mesh) was the optimumsize range. Azadirachtin which is a key ingredient of neem is quite stable in PNF. This article delineates material and energy balance to produce 1 tonne of PNF on a commercial level by using hammer mill. The particle size distribution models and classical energy consumption models were used to fit the experimental data generated by changing the hammer millscreen.
