Drying & Handling Equipment for Fertilizer Production

Fertilizer granule production requires precise moisture and temperature control at the drying and cooling stages to produce a free-flowing, non-caking product with good mechanical strength. Fluidized bed dryers provide the precise temperature and residence time control needed for NPK granules, urea and ammonium nitrate products — where over-drying causes brittleness and under-drying causes caking in storage. Fluidized bed coolers reduce product temperature to safe handling levels after drying.

Rotary coolers are the standard for high-capacity operations where fluidized bed footprint is a constraint. Bucket elevators are the preferred method for vertical transport of dry fertilizer granules — enclosed, dust-tight, and capable of handling the fragile granule product without attrition. Product silos with cone-bottom discharge provide the buffer storage between production and bagging or bulk loading operations.
