SSP Production Line | Turnkey Phosphate Fertilizer Plant Solutions

Turnkey SSP Fertilizer Plant Solution

SYM provides complete SSP production line equipment and turnkey plant solutions based on proven sulfuric acid wet-process technology. Each system integrates phosphate rock preparation, precise acid dosing and mixing, controlled acidulation and curing, crushing, dust and fluorine gas treatment, and final packaging.

Each SSP plant is configured according to phosphate rock characteristics, sulfuric acid specifications, required capacity, site conditions and automation requirements. This supports stable production, controlled emissions and reliable plant operation for the specific project.

Powder SSP Production Line vs. GSSP Production Line

Powder SSP is produced by reacting finely ground phosphate rock with sulfuric acid, followed by curing, crushing and product conditioning.

Granular SSP is produced by adding granulation and related finishing steps to the SSP process.

Key Differences:

Appearance: SSP – powder; GSSP – uniform granules.
Application: SSP – direct application & fertilizer blending; GSSP – easier handling, storage & mechanized spreading.
Production: GSSP adds a granulation step to the SSP base.

Product Advantages

The process is configured according to phosphate rock composition, reactivity, fineness and available sulfuric acid specifications.

Accurate acid dosing and controlled mixing help maintain stable acidulation conditions and consistent production.

Pan den or continuous belt den configurations can be selected according to plant capacity, operating requirements and site layout.

Dust collection and wet gas scrubbing systems can be configured according to phosphate rock characteristics and local environmental requirements.

The plant can be supplied with semi-automatic control or centralized DCS control according to the project scale and operating plan.

SYM provides process design, equipment manufacturing, plant layout, installation guidance, commissioning and operator training for new SSP plants and existing plant upgrades.

FAQs

What raw material information is required for SSP plant design?

Please provide the available phosphate rock analysis, particle size or grinding conditions, sulfuric acid specifications, target product requirements and required plant capacity.

Can different grades of phosphate rock be used?

Different phosphate rock sources may require different grinding, acid dosing, mixing and curing conditions. The raw material analysis should be evaluated before determining the final process and equipment configuration.

What is the difference between an SSP and GSSP production line?

A powder SSP line focuses on acidulation, curing, crushing and product conditioning. A GSSP line adds granulation and related drying, cooling and screening equipment to produce uniform granules.

How much does an SSP production plant cost?

The plant cost depends on capacity, phosphate rock preparation requirements, curing system, gas treatment configuration, automation level and scope of supply. A preliminary budget can be prepared after reviewing your basic project information.
