增效碳铵挤压造粒性能试验研究

Test Study on Properties of Granulation for Ammonium Bicarbonate Based Blending Fertilizer

试验研究了普钙系列增效碳铵和磷铵系列增效碳铵的压缩性能、颗粒强度与模孔直径和长度、挤压力的关系，为造粒机的设计提供依据。

The compressibility of two kinds of smmonium bicarbonate based blending fertilizers is tested. The relationships between the strength of fertilizer particles and the diameter and the length of the hole in the mould plate, the extruding force are also studied. The results can be used for designing extruding granulaters.
