The effects of some constructive properties and operational parameters of rotary fertilizer spreaders on fertilizer flow rate

Bu çalışmada diskli gübre dağıtma, makinalannda, amonyum sülfat ve üre gübrelerinin disk üzerine olan akışı incelenmiştir. Bu amaçla, değiştirilebilir farklı orifıs şekilleri (üçgen, kare, trapez, uçları kavisli kare ve dikdörtgen) değişik alan büyüklüklerinde (150, 300, 450, 600, and 750 mm2), depo tabanı ve depo yan yüzeyi olmak üzere iki orifıs konumunda kullanılmıştır. Denemeler 300, 540 ve 780 $min^{-1}$ karıştırıcı hızlarına göre yürütülmüştür. Sonuç olarak, incelenen tüm faktörlerin debi Üzerine etkili oldukları belirlenmiştir.

Diskli gübre dağıtma makinalarında bazı yapısal özelliklerin ve işletme parametrelerinin gübre debisine etkisi

This study aims at investigating the flow rate of urea and ammonium sulfate through different orifices onto disc in rotary fertilizer spreaders. For this reason, interchangeable orifices with different shapes (triangular, square, trapezous, square-like, and rectangular) in various sizes (150, 300, 450, 600, and 750 mm2) at two positions (bottom and wall of hopper) were used in a hopper. Experiments were conducted according to three agitator rates of 300, 540, and 780 $min^{-1}$. As a result, all the factors investigated had significant effect on the flow rate.
