摘　　要：通过建立模型试验说明,为预防化肥粉末结块,传统采用喷雾或者喷洒的方法,液体包裹剂或惰性粉体包裹剂包裹粉末时,虽有较好的防结块效果,但包裹剂用量较大,同时在包裹时往往存在操作死角,造成包裹不均匀,影响防结块效果。Through model test, this article showed that, to prevent fertilizer powder from caking, traditional methods, such as spraying liquid package or inert powder package, often need larger dosage and have operation dead angle, resulting in uneven package, then affect Anti - caking effect, although have better anti - caking effect.
