The phosphorus chemical industry chain is enjoying sustained prosperity. Phosphate fertilizer production accounts for the largest share of phosphate rock consumption. As a mainstream product, diammonium phosphate (DAP) is critical to safeguarding food security and the sustainable development of agriculture. Grinding it down to a specific fineness effectively increases its specific surface area, thereby accelerating its dissolution rate and improving mixing uniformity, enabling precise adaptation to refined application requirements across diverse agricultural scenarios. Currently, the core demand of modern agriculture lies in promoting high-value and efficient utilization of phosphorus resources, so as to achieve higher quality, reduced application dosage and improved efficiency for fertilizers.
A major state-owned enterprise, a leader in phosphate rock mining and phosphate fertilizer manufacturing, planned to build new production lines to meet the phosphate fertilizer industry's demand for refined, intelligent and green development. Relying on comprehensive strengths across multiple dimensions, including reliable equipment performance, sophisticated processing technology, guaranteed delivery and high-quality after-sales service, SBM gained the recognition and trust of this state-owned enterprise.
The customer purchased three complete sets of SBM MTW European Trapezium Grinding Mills in one go, establishing two high-efficiency diammonium phosphate grinding production lines. The lines meet strict requirements for the fineness and quality of finished products, setting a benchmark demonstration project for the intelligent, green and high-efficiency application of phosphate fertilizers in the region.
Material: Diammonium Phosphate (DAP)
Fineness: 100 mesh
Application: Phosphate Fertilizer
Equipment: Three Complete Sets of MTW European Trapezium Grinding Mills
SBM assembled an expert team to conduct all-round consultation, assessment and site planning for the project. The team held repeated discussions, revisions and optimizations of the technical scheme with the customer. Considering safety, energy conservation, environmental protection and other key factors, we customized a systematic solution covering feeding, dosing, grinding, collection, drying, conveying and intelligent control.
As the core main equipment of the project, SBM MTW European Trapezium Grinding Mill adopts multiple innovative technologies including integral bevel gear transmission, curved air duct and thin oil lubrication, effectively solving traditional pain points in the grinding process such as low efficiency, high energy consumption and uneven fineness. The equipment operates under negative pressure and fully enclosed conditions, with supporting pulse dust collectors preventing dust leakage, achieving a win-win result for both economic and environmental benefits.
Technical Features of MTW European Trapezium Grinding Mill
It adopts integral bevel gear transmission technology, featuring precise transmission ratio, low energy loss and high grinding efficiency. It can deliver a stable production capacity of 3–55 tons per hour, satisfying the continuous and large-scale production demands of phosphate fertilizer manufacturing.
Equipped with a variable-frequency controlled classifier, the fineness of finished products can be adjusted within the range of 80–325 mesh, ensuring uniform powder particle size and meeting the strict raw material fineness requirements of phosphate fertilizer production processes.
Both the main shaft transmission system and fan transmission system of the equipment adopt thin oil lubrication. Compared with traditional grease lubrication, it delivers lower lubrication resistance and lower operating temperature, effectively extending bearing service life.
It features a negative-pressure fully enclosed operation system and is fitted with pulse dust collectors. The dust emission concentration is lower than national environmental protection standards, which greatly reduces environmental pollution and complies with green production specifications.
It is equipped with a PLC automatic control system, which ensures easy operation and low failure rates. The mill can run continuously around the clock, reducing manual labor intensity and improving overall production efficiency.
Since the project was put into operation, the two grinding production lines have maintained stable working conditions, and the processing capacity of each individual line has fully met the design targets. Especially during peak agricultural seasons such as spring ploughing and autumn sowing when demand for agricultural materials surges, the lines can operate continuously at full load, providing solid support for the customer to seize key production windows and ensure adequate phosphate fertilizer market supply.
From the commissioning of every single component to the high-speed operation of the entire production line; from the on-site follow-up by the engineering team throughout the project to the timely responses of the after-sales service team; from the supply of standalone equipment to end-to-end full-process service support - SBM has always maintained a professional and reliable approach, rapidly responding to equipment maintenance and operation requirements. It minimizes risks such as unplanned downtime and constrained production capacity, ensuring sustained and stable operation of the production lines. The thoughtful and comprehensive services provided by SBM have received high praise from the customer.
Going forward, SBM will continue to focus on the core production pain points of the phosphorus chemical industry. With more advanced equipment technologies and improved full-lifecycle services, we will help more industry customers achieve high-quality development.
