Since 2025, the phosphorus chemical industry has maintained a high prosperity level. Phosphate rock, as an upstream resource, has gained prominent strategic value with prices staying firm. The supply-demand relationship of midstream and downstream products has improved alongside orderly structural optimization. Looking ahead, driven mainly by changes in phosphate rock supply and demand, the phosphorus chemical industry chain will continue to enjoy robust market conditions.
As a non-renewable strategic mineral resource, phosphate rock is a key raw material for ensuring food security and supporting the development of the new energy industry. Sustained agricultural demand and explosive growth of the new energy sector have pushed up domestic procurement of phosphate rock, tightening the supply-demand balance. To ease supply shortages, China's imports of phosphate rock have risen sharply year on year.
Currently, the phosphate rock industry chain extensively covers agriculture, industry, new energy, high-end manufacturing and other vital fields. While its applications are shifting toward high value-added products, agricultural production remains its core application. Globally, around 60% of phosphate rock demand comes from phosphate fertilizer production.
Production Process of Phosphate Fertilizer
Phosphate is one of the three essential nutrients for crop growth. As the world's largest phosphate fertilizer producer, China relies on the industrial chain of phosphate rock - phosphoric acid - ammonium phosphate to guarantee phosphorus supply for domestic grain production.
Phosphate fertilizer production is mainly divided into two categories: wet process (acid process) and thermal process, with specific procedures varying by raw materials and end products.
Sulfuric Acid Process (Wet-Process Phosphoric Acid)
It is the dominant technology for producing high-concentration phosphate fertilizers worldwide. Featuring superior economic efficiency, it is ideal for large-scale continuous production. In this process, phosphate rock powder is decomposed with sulfuric acid to extract phosphoric acid. The product is then neutralized, concentrated and granulated to make monoammonium phosphate (MAP), diammonium phosphate (DAP), single superphosphate (SSP), triple superphosphate (TSP) and other products.
Thermal-Process Phosphoric Acid
Phosphate rock is reduced in an electric furnace to produce yellow phosphorus, which is then combusted and hydrated to prepare high-purity phosphoric acid. This process yields products of high purity, applicable to the production of electronic-grade and high-quality food-grade phosphoric acid, which are further processed into high-purity phosphate fertilizers and fine phosphate products.
Core Equipment for Phosphate Rock Pulverization
The wet process is currently the mainstream route for phosphate fertilizer production. As the pivotal pre-process of the entire production line, raw phosphate rock grinding directly affects the contact area of materials in subsequent reactions, chemical conversion rate, finished product grade and overall energy consumption. It is a critical upstream procedure to ensure stable and efficient operation of phosphate fertilizer production lines.
In response to actual production demands of the phosphate fertilizer industry, SBM has developed four core product portfolios. They cater to customized requirements for different production capacities and diverse working conditions, delivering a full-coverage and highly adaptable overall solution for phosphate rock grinding. Integrating outstanding advantages such as high grinding efficiency, low energy consumption, intelligent control and eco-friendliness, our equipment provides solid core support for stable production, quality improvement and cost reduction in phosphate fertilizer processes.
Targeting the characteristics of phosphate rock, SBM has accumulated extensive experimental data and engineering experience, helping clients in the phosphate industry successfully launch projects and realize tremendous value enhancement from raw ore to high-value products.
Amid the upgrading of the phosphorus chemical industry, SBM provides intelligent equipment and systematic solutions to address the triple challenges of resources, costs and environmental protection, and helps enterprises build an efficient, eco-friendly and intelligent production system. Driven by the new energy revolution and agricultural modernization, phosphate rock processing is advancing toward refinement and sustainability. SBM is willing to take technology as the link and work with the industry to create a new landscape of high-quality development.
