Abstract
The shearing characteristics of eight kinds of fertilizers were investigated to analyse their fluidity.
The fluidity of fertilizers is affected by how they expand and change their void-ratios and internal friction, when sheared. Cohesion in wet fertilizers obstructs their expansion and reduces their fluidity.
The larger in size and the uniformer in its distribution the particles of fertilizers are, the more their expansion and decrease of internal friction by shearing are. So that, the granularization of fertilizer is fundamentally effective to improve their fluidity.
