Fertilizer production technology - Granulation - dry granulation - Principle of roller extrusion granulation 2
Date:2024/07/12
After in-depth discussion of the process characteristics and advantages of the roll extrusion granulation method (Double Roller Press Granulator), it is not difficult to find that the key reason why this technology can stand out among many granulation methods is its innovative working principle and high efficiency implementation. It cleverly transforms raw materials directly into granular products with specific shapes and particle sizes through the precise extrusion of rollers under high pressure, which not only simplifies the production process, but also greatly improves product quality and yield. Based on these significant advantages, the Double Roller Press Granulation method has been widely used in many fields, and has become a shining pearl in particle preparation technology.
Forth, Process characteristics and advantages
Short process: The preparation process of roller extrusion granulation from raw materials to finished particles is relatively simple, reducing intermediate links and energy consumption.
Low energy consumption: Because mechanical pressure is used for granulation, there is no additional heating or drying (Rotary Dryer) process, so the energy consumption is low.
Large output: reasonable equipment design, high production efficiency, can meet the needs of large-scale production.
High product purity: no wetting agent or other additives are added in the granulation process to ensure the purity and quality of the product.
Wide range of application: not only suitable for fertilizer raw materials (such as ammonium sulfate, potassium chloride, etc.), but also widely used in white carbon black, inorganic salts, pigments, detergents, pesticides and other fields.
Fifth, Application examples
In practical applications, the roll extrusion granulation method has been widely used in the production of various compound fertilizers, special fertilizers and industrial recovery dust materials. In the field of fertilizer production, ammonium sulfate, diammonium phosphate, potassium chloride and other raw materials can be prepared by roller extrusion granulation method with high concentration of compound fertilizer (New Type Two In One Organic Fertilizer Granulator) to meet the nutrient needs of different crops. The method can also be used to treat industrial recycled dust materials, such as iron foundry dust, converter dust, etc., to realize the recycling of resources and environmental protection.
