Using double roller press granualtors to process NPK blended fertilizers offers multiple advantages, including a simple process, controllable costs, and environmental efficiency, as detailed below:
1. No need for additional binders: The double-roller extrusion granulator directly compresses NPK raw material powder into shape using high mechanical pressure, eliminating the need for binders. This reduces raw material costs and prevents foreign components from affecting fertilizer purity and efficacy, ensuring accurate nutrient ratios in the blended fertilizer.
2. High granulation efficiency and strength: The equipment uses a double-roller compression method to quickly press uniformly mixed NPK raw materials into granules. The finished granules have high density and are not easily broken, preventing dust generation during transportation and application, thus enhancing usability.
3. Environmentally friendly and energy-efficient process: The entire granulation process does not require a drying step, saving energy compared to traditional wet granulation methods. It also reduces wastewater and exhaust emissions, aligning with green production requirements. Furthermore, the compact structure of the equipment requires minimal space, making it suitable for NPK blending fertilizer produciton lines of various scales.
4. Wide range of raw material adaptability: It can flexibly process NPK raw materials with different ratios. Whether it's high-nitrogen, high-phosphorus, or high-potassium blended fertilizers, stable granulation can be achieved. It can also accommodate the addition of functional components such as humic acid and biological agents, meeting customized production needs.
