Granular compound fertilizer production technology/mechanism/principle of granule formation:
There
are two technology/ways/principles for the production of granular compound
fertilizer. These are:
i)
Agglomeration Type Process
ii)
Accretion Type Process
i) Agglomeration Type Process:
In
this process, 50-75% of the raw materials are dry solids. These solid particles
are assembled and joined together by a combination of mechanical interlocking
and cementing - much as a stone wall by using stones of a various size and
mortar as cementing agent. The cementing medium for fertilizers is derived from
salt solutions, for example Ammonium Phosphate Slurry.
