Overview

Granulated Urea Superphosphate for Better Handling and Better Use

A phospho-nitrogenous fertilizer route built around urea and superphosphate to deliver a usable and market-ready granulated product.

Jobson’s granulation page presents Urea SSP Granulation as a complex NP fertilizer route, highlighting a composition such as 5:12:0:10 and positioning the product as a practical nutrient source delivering nitrogen, phosphate, calcium, and sulfur in granulated form.

The page also emphasizes that urea superphosphate can support bulk blending and can be combined with other fertilizer materials when required for target nutrient formulations. Compared with powder forms, granulation improves handling, reduces wash-away losses, and helps the product remain in soil for longer practical utility.

Process Background

Two-Stage Preparation Logic for USP

The website frames the preparation route as a two-stage process that links reagent preparation with SSP granulation and ratio control.

The process background explains that Urea Superphosphate is made using urea as a cost-effective nitrogen source and phosphate rock as a cost-effective source of P₂O₅. It describes a method in two stages: first, preparation of a urea-based solution or reagent under controlled conditions, and second, feeding that preparation with SSP granulation while maintaining process ratio and granulator control.

The page also notes that the reaction is exothermic and that the process can produce USP granules suitable for granulation, bulk blending, or further blending with other fertilizer materials such as MOP / KCl, potassium sulphate, MAP, or DAP for broader NPK product strategies.

Process Description

Plant Flow from SSP Powder to Screened Granules

A drum-based granulation line with drying, cooling, screening, recycle, and dust-control integration.

According to the Jobson page, Urea Granulated Single Super Phosphate is manufactured by feeding SSP powder to the granulation plant. Inside the rotating granulator drum, the SSP powder is mixed with water up to about 12%, allowing granules to form from the powder feed.

The granules are then discharged to a dryer drum, where heating is used for drying, followed by transfer to a cooler drum. After cooling, the material moves to vibrating screens for desired mesh separation, while undersize and oversize fractions are handled through recycle and crushing loops to stabilize the plant output.

Granulation Drum: Powder feed mixed and conditioned for granule formation.

Dryer Drum: Moisture reduction after granulation.

Cooler Drum: Product cooling before screening.

Screening & Recycle: Size control through undersize return and oversize crushing loop.

Feed & Conditioning

SSP powder is fed into the line and mixed in the granulator with moisture addition for granule build-up.

Drying & Cooling

The freshly formed granules move through dryer and cooler drums for stabilization before classification.

Screening & Recycle

Undersize is recycled to granulation, while oversize material is directed for crushing and return.

Final Product Handling

Desired product fraction is separated for packing and sale as granulated fertilizer.

Screening Logic

Two Vibrating Screens Maintain Product Size Control

The website highlights separate undersize and oversize screen functions for product quality and recycle efficiency.

The first stage is the undersize vibrating screen, where material below 1 mm is separated and returned to the granulator drum. The oversize material from this screen is then sent onward for the next screening stage.

The second stage is the oversize vibrating screen, where the page identifies the desired product fraction around +1 to -4 mm. Material retained as oversize is sent to the crusher and recycled back to the granulator, while finished granules are packed in 50 kg HDPE bags for sale as GSSP.

Environmental & Process Control

Dust Capture and Discharge Management

Granulation dust evolved in the process is managed through cyclone-based scrubbing and controlled air discharge.

Dust Evolution

The process description notes that USSP dust evolves during granulation and associated plant operations.

Twin Cyclone System

Dust is handled through a twin cyclone arrangement associated with the blower provided for the dryer drum circuit.

Stack Discharge

Air is discharged through a chimney indicated on the page at a height of 30 meters.

Operational Value

Why Granulated USP Adds Practical Value

Improved physical form, easier handling, and compatibility with downstream fertilizer use patterns.

The Jobson page specifically highlights improved nutrient uptake efficiency and positions the product as a more useful form than powder because it does not dissolve as easily or get washed away as quickly. In practical plant and market terms, this supports better handling, better storage behavior, and stronger application performance.

The page also notes that one advantage of the process is production of urea superphosphate compatible with bulk blending alongside fertilizers such as urea and triple superphosphate, creating wider formulation and marketing flexibility.
