On May 23, 2026, a fertilizer manufacturer from Bulgaria contacted us to discuss a new 50,000 TPY NPK compound fertilizer production line. The company supplies compound fertilizers to agricultural distributors and farming cooperatives across Bulgaria and neighboring countries. As demand for customized NPK formulas continued to grow, the customer’s existing production line could no longer meet market requirements. Besides increasing annual output, the customer also wanted to improve production flexibility, batching accuracy, energy efficiency, and long-term operating profitability. After reviewing the raw materials, production targets, and workshop layout, our engineers designed a complete rotary drum granulation production line. The solution integrates automatic batching, granulation, drying, cooling, screening, coating, automatic packaging, and centralized PLC control.
How Can I Build a 50,000 TPY NPK Fertilizer Production Line with Multiple Formulas?
The customer’s first concern was production flexibility. They wanted one production line that could manufacture approximately 50,000 tons per year (8–10 T/H) while switching easily between different NPK fertilizer formulas.
Next, the production line transfers the mixed materials to the rotary drum granulator. We selected this model because it delivers stable continuous production and supports medium- and large-scale NPK fertilizer manufacturing.
The entire production line allows the customer to manufacture multiple fertilizer grades, including 15-15-15, 20-10-10, and other customized NPK formulations without changing the core equipment.
How Can I Maintain Accurate Batching and Consistent NPK Quality?
The customer also wanted to keep fertilizer quality consistent while producing multiple NPK formulas. Frequent recipe changes and inaccurate weighing could increase raw material losses and reduce nutrient consistency.
How Can I Reduce Operating Costs While Meeting Environmental Requirements?
Besides production capacity, the customer focused on operating costs. They wanted to reduce energy consumption and labor requirements while maintaining a cleaner production environment.
In the end, YUSHUNXIN delivered a customized 50,000 TPY NPK compound fertilizer production line tailored to the customer’s production goals and future expansion plans. By combining automated batching, rotary drum granulation, PLC control, and environmental protection systems, the solution helps improve fertilizer quality, production efficiency, and long-term operational reliability while supporting the customer’s continued growth in the Bulgarian fertilizer market.
