Granulated Single Super Phosphate Plant

Granulated Single Superphosphate:

The granulated SSP is produced by granulation of SSP in the granulation plant. The granulation is done because the nutrients remain available for a longer time. The granule releases the nutrients very slowly. This process improves the nutrient utilization.

PROCESS OF MANUFACTURING OF GRANULATED SINGLE SUPER PHOSPHATE:

The measured quantity of the cured SSP is mixed properly with filler in a mixer. The homogeneous mass is then processed in the granulator drum.. The granulator drum rotates at very low RPM. The material goes up with the wall of granulator for some height and then starts rolling back. A fine spray of water at this stage starts the process of granulation and as the material rolls on, the size of the granules increases. This material is transferred to the dryer drum with the help of a conveyor belt. The Furnace attached to the dryer generates hot air which is made to pass through this wet material. The evaporation & condensation of water gets deposited on the small granules and further enhance the size of the granules. With the hot air stream the material gets dried. The material is then passed through the cooler drum for cooling. The cooled material is transferred to the screens to remove the oversize & undersize granules from the product. The oversize granules after crushing & under size granule are mixed with the raw feed for reprocessing. The plant is equipped to deal with air pollution inside the plant and stack flue gases.

The product is packed in 50 Kg bags.
