Abstract

The aim of this study was to establish the rotation in?uence of the meter component and the aperture of the hopper over the mass ?ow rate of solid fertilizer in a meter equipped with two outputs for dosed material, intended for use in small capacity planters. The meter was evaluated in laboratory using the fertilizer NPK 05-20-20, characterized according to water content, bulk density, particle size and repose angle. The experiment was designed to evaluate the combined effect of the angular speed of the rotor blades and the aperture of the hopper over the meter mass ?ow rate, in a factorial arrangement 4x4, with fve replications. The mass ?ow of this fertilizer was found to be directly proportional to the angular speed of the two output meter rotors and to the aperture between the hopper and the rotor. There was interaction between the variables. The metering system developed was able to dispense the fertilizer with estimated distribution ratios compatible with agricultural practices.
