A large Bulgarian manufacturer of agrochemical products has entered a new stage of development. The company has set a strategic goal to expand its presence in the market. This required a significant increase in production volumes.. The client also needed the ability to quickly switch between different NPK fertilizer formulas. Precise adherence to the recipe became a key quality factor. An equally important task was to guarantee stable and uninterrupted operation of the new production. We, together with the customer’s technical specialists, conducted a detailed needs audit. Based on this analysis, we formed the concept full technological cycle. The basis of this enterprise was a reliable production line for NPK fertilizers 100 000 ton. The concept included the preparation of raw materials, precise dosing, granulation and finishing.

How to ensure composition accuracy during production 15+ NPK grades on one line?
The customer planned to produce more than fifteen different brands of fertilizers. Frequent formulation changes created a risk of cross-contamination. We proposed a clear scheme for organizing raw material flows. First we classified all bulk components. Next, we designed a separate storage system for each component. Modern dosing system became a key element of the line. It provided highly accurate weighing of each ingredient. Then we introduced programmable prescription cards. The operator could quickly select the desired brand on the control panel. Automatic purging of transport lines after each recipe change eliminates mixing. Regular monitoring of finished product samples confirmed the stability of the composition. Thus, NPK fertilizer production line 100 000 tons reliably performs tasks of a complex assortment.
How to achieve design capacity in 100 000 tons per year when working with different raw materials?
The client noted the inconsistent characteristics of incoming raw materials. The moisture content and granulometry of phosphate rock could vary. These fluctuations affected the speed of the granulation process. We focused on setting up and synchronizing key nodes. Firstly, we have optimized the work mixer-granulator. Adjustment of blade angle and rotation speed improved granule formation. Secondly, we have adjusted the thermal regime in the drying drum. The system automatically adjusted the temperature to the humidity of the semi-finished product. Third, we have adjusted the efficient operation of the cooler. Stable cooling secured the strength of the granules and prevented caking. Powerful aspiration system controls dust levels. As a result, all sections of the line worked in a balanced manner. This allowed us to reach planned performance indicators without downtime..

Efficient use of energy was critical to the customer. We have worked on several areas to optimize costs. We paid special attention to the drying area. The heat recuperator became the first important element. This device uses hot air from the cooler to heat the dryer inlet.. The next step was to insulate the hot surfaces of the equipment. Thermal insulation reduced losses to the environment. We also offered a drum loading level control system. Sensors prevented equipment from running idle or when overloaded. Optimization of fan operation and pumps provided additional energy savings. The client received a detailed report on energy saving modes. These measures ensured a significant reduction in operating costs for the NPK fertilizer production line 100 000 ton.
