Drum granulation of NPK fertilizers
Powder Technology, 2000Nitrate-based NPK fertilizer was granulated in a bench scale drum granulation unit. The initial fertilizer possessed a particle size distribution similar to those in industrial granulation units. In this work, three factors are identified affecting the degree of fertilizer granulation, these are solution to solid phase ratio, the binder viscosity and ...

Compression testing of granular NPK fertilizers
Nutrient Cycling in Agroecosystems, 1997The crush strength of granular NPK fertilizer has been accurately determined using Instron compression testing equipment. Stress-strain analysis shows a distinctive break point followed by break up of granule fragments. The force required to crush the granules is a function of the granule diameter but the calculated pressure required to crush each ...
