Abstract The most famous machines type of solid chemical fertilizers is the centrifugal distribution machine, because the advantage of low power necessary, simplicity of mechanical design, ease of maintenance, high performance and wide operation width. But, the most important thing wrong with these machine is the lack of distribution accuracy of fertilizers at the rate desired. The objective of the study:- The aims of this study are: 1- To establish and evaluate a computer simulation to be a useful part for developing mathematical model, which simulates the discharge and spread of the real fertilizers particles from centrifugal spreader. 2- To determine, the possibility range of using this model with the different fertilizers particles, and conclude the using possibility range of the same model to deduce the fertilizers distribution patterns after that. |
