Characterization of the Model 2.7 fertilizer treatment equipment shaped granular to optimize fertilizer application granulation of pearl fertilizer

Abstract

The technique of application of fertilizer has evolved and nowadays agronomists propose to producers the
application of fertilizer pellets in plot. This practice has several advantages including the reduction of
application time and the gradual release of nutrients. The fertilizers available on the markets are in pearl
form, hence the need to make pellets. The aim of this study is to evaluate the technological performance
of the Model 2.7 fertilizer granular, in order to optimize its yield for the production of urea granules, in
order to make nitrogen fertilisation more profitable in a context of rising fertilizer costs. In addition, the
use of urea pellets should make it possible to optimize the efficiency of fertilization while minimizing
environmental nuisances related to common practices.
Five (5) granulation tests of the urea samples (15 kg) were performed. The optimization parameters
measured in the gold of the operation of the equipment are: the rate of granules, the rate of broken
granules, the rate of non-carbonated fertilizer in losses of uncompressed powder, and the overall
granulation yield. The obtained results show that the average pellet flow rate is 432.8 ±35.7 kg/h, the
broken pellet flow rate is 48.3 ±32.7 kg/h or 10.04% of the total pellets. An uncompressed powder loss
rate of 31.8 ±2.5%. The overall granulation yield is 67.34 ±2.8%. This performance is low, the tool must
be improved to avoid product losses during the granulation operation. Tests have shown that equipment
maintenance after each operation takes long time.
