This study addresses sustainable agriculture and income generation for small to medium-
scale root crop farmers through an innovative fertilizer production solution. Focused on the

"Design and Development of a Compact Crushing and Pulverizing Machine to Produce
Fertilizer Using Chicken Bones," it introduces a multifunctional machine driven by a 1HP
motor, integrating a drying mechanism, crusher, and high-speed pulverizer or streamlined
production.
The drying process at 180 degrees Celsius for 1 hour successfully removed 42.792% of
moisture from chicken bones, slightly below the 50% to 45% target. Subsequent crushing
operations yielded 12-to-5-millimeter bone fragments, surpassing traditional hammer
mills. The high-speed pulverizing machine refined bone particles to an impressive 400-450
microns. In rigorous testing, the machine produced 0.823kg of dried chicken bones. Quality
assessment revealed elevated nutrient content, with phosphorus, nitrogen, calcium, and
moisture levels at 5.497%, 1.355%, 1.440%, and 17.208%, respectively, surpassing
market-available bone fertilizer.
Comparison with market values emphasized the project's success, outperforming existing
fertilizers in all tested categories. The "Design and Development of a Compact Crushing

and Pulverizing Machine" offers a sustainable, cost-effective solution for chicken bone-
based fertilizer production, addressing agricultural needs and creating additional income

streams for farmers.
