Review of vane design influence on centrifugal fertilizer spreading outlet properties

Glademir Karpinski Junior, Jose Antonio Portella

Abstract :

Particle motion on disc and early ballistic flight are reviewed. Resistance and propelling forces are discussed to acquire fundamental information on their interaction with vane design and outlet properties. The influence of the metering device, hopper, and later ballistic flight of the granular fertilizer are not addressed. Unlike lengthwise profiles, transversal design effects on the overall kinetic energy loss are not well known and may have an influence on ballistic throwing quantities and spatial fertilizer distribution evenness on the soil, by imposing extra resistant components on the particles.
