ec@shyychina.comProject Scope: GSSP production line equipment, process design and plant engineering services. Finished fertilizer products are not supplied.
SYM provides integrated process and equipment solutions covering the complete GSSP production route from raw material preparation to granulation and final packaging. The plant combines controlled acidulation and curing with granulation, drying, cooling, screening and material recycling systems to support stable operation and consistent particle-size control.
Raw Material-Based Process Design: Conduct lab tests using your specific phosphate rock to determine optimal acid-to-rock ratio and granulation parameters, providing a customized process package.
Site Layout & General Plot Plan: Design the most efficient production line layout based on your existing workshop or new land plot, minimizing footprint and ensuring smooth logistics.
Deep Customization of Core Equipment: Customize granulator size, dryer heat source (coal, gas, steam) based on capacity and product specifications.
Environmental & Control Options: Dust collection, fluoride-containing gas treatment and PLC or DCS control systems can be configured according to the process and local project requirements.
Installation & Commissioning Support: SYM provides installation guidance, commissioning assistance and operator training according to the agreed project scope.
Cured powder SSP is continuously fed and conditioned before entering a rotary drum granulator or disc granulator. The suitable granulation process is selected according to the feedstock properties, required capacity and target granule size.
Once formed, the wet granules immediately enter a heavy-duty rotary dryer to rapidly eliminate moisture, followed by a rotary cooler that thermally stabilizes the particles and increases their mechanical hardness to prevent crushing. The hardened granules are then transferred to a multi-deck vibrating screen, which strictly classifies the product, routing on-spec sizes to the final coating machine for anti-caking surface treatment, while directing fines and oversized material back into the recycling loop.
