Adaptability Ballistic Model for Granular Manure Fertilizers Spreading

Abstract

The ballistic model adaptability for the granular manure fertilizers spreading is a key to investigate the most effective model to spread fertilizes and to find the most economic use of the organic fertilizers. This method is suggested to minimize the quantity of expensive and extremely time consuming experiments. The object of this research is to investigate if ballistic model can be used to optimize spreading of granular organic fertilizer from agricultural waste products. The aim of the investigation is to check the adaptability of the ballistic model for granular manure fertilizers spreading. Granular organic fertilizers have different physical characteristics that is determined by the process of preparation. These physical characteristics of fertilizer can change the spreading characteristics and it is important that the ballistic model gives the opportunity to change these characteristics and check the most optimal fertilizers characteristics and way of the spreading.The variance method was used to investigate issues around spreading of granular manure fertilizers. For the evaluation of the aerodynamic properties of the pallets were used test stand - classification K- 293, air flow meter Delta OHM DO 9847 and electronic scales IPC 3WP. The FEM pallets aerodynamic and ballistic models were created. The pellet aerodynamic properties model was created with the complement FlowSimulation program SOLIDWORKS software. 500 pallets were randomly chosen to be characterized and each measurement was repeated 5 times to get statistically meaningful results. After the analysis was completed and arithmetic averages were evaluated results showed that the diameter of the granular compost fertilizer was: Manure I 5.28 ± 0.8 mm, Manure II 4.75 ± 0.12 mm.The prevailing length of the pellets was: for Manure I was 10 to 12.5 mm and for Manure II was 5-7.5 mm.[...]
