Fertilizer Production Line: Why is the Rotary Drum Granulator the Core?

In modern fertilizer production lines, the granulation process directly determines the fertilizer's form, nutrient uniformity, and storage performance. Traditional granulation equipment often slows down production line efficiency due to poor granulation and high energy consumption. The advent of the rotary drum granulator has completely changed this situation. Why has it become the "core" of the fertilizer production line? The core value of the drum granulator in the npk fertilizer production line lies in the efficient granulation of raw materials. During operation, the mixed wet raw materials are fed into the tilted and rotating granulation drum. The lifting plate in the drum continuously lifts and sprinkles the raw materials, and at the same time, the atomized adhesive is evenly sprayed. The raw materials gradually agglomerate into round particles under the action of gravity and friction, and then become qualified finished products after screening and drying. Whether it is producing organic fertilizer, compound fertilizer, or slow-release fertilizer, it can accurately control the particle size and hardness by adjusting the rotation speed, inclination angle and adhesive dosage to adapt to the production needs of different fertilizers. Its advantages within the production line are irreplaceable. Firstly, its granulation efficiency far exceeds that of traditional equipment. A single drum granulator can process dozens of tons of raw materials per hour, meeting the needs of large-scale fertilizer production. Secondly, its high and uniform granulation rate reduces waste during subsequent screening and reduces raw material loss. More importantly, it seamlessly integrates with upstream and downstream equipment on the production line—handling material transport from the raw material mixer at the front end and providing a stable feed to the dryer at the back end, ensuring continuous operation of the entire production line and avoiding downtime caused by equipment compatibility issues. As the fertilizer industry develops toward scale and high quality, rotary drum granulators have become standard fertilizer equipment in modern production lines. Their efficient and stable granulation capabilities support fertilizer companies in increasing production capacity and ensuring product quality, helping agricultural production achieve high-quality fertilizers.
