SUMMARY

To design a fertilizer pellet machine producing suitable pellet shapes for fertilizer spreader, a

research group of Institute for Engineering Development, Hanoi University of Agriculture has

designed and manufactured a model of fertilizer pellet machine (mortar-pestle principle). Testing

results In actual working conditions showed that the machine working principle and main part

designs are reasonable. The produced pellets have approximately spherical shape with size and

compression degree met agronomic requirements. The pellets are suitable for working of the

fertilizer spreader to bury them into the soil. However, the productivity and reliability of the machine

are still low.

This article presents some research results on improving design of the fertilizer pellet machine to

increase productivity and reliability of the machine. The results will be a basis for manufacturing a

new commercial possibility machine and contribute to mechanization of spreading fertilizer for rice

and some other crops.

Key words: Fertilizer, fertilizer pellet, fertilizer pellet machine.
