Organic Fertilizer Granulation Technology: Choosing the Right Solution for You

In modern organic fertilizer production, selecting the appropriate granulation technology is crucial. Different granulation processes have their own characteristics in terms of capacity, energy consumption, raw material adaptability, and product quality. Understanding these differences helps production enterprises make informed choices based on their own conditions and market demands. This article introduces three mainstream organic fertilizer granulation technologies to help readers find the most suitable production solution for their needs. Overview of Three Mainstream Technologies Currently, the organic fertilizer industry mainly uses three granulation processes: horizontal mixing and extrusion granulation, flat die extrusion granulation, and rotary drum granulation. Each technology has its unique working principle and applicable scenarios, and the selection requires consideration of factors such as raw material characteristics, product requirements, and investment budget. Horizontal mixing and extrusion granulation technology uses the mechanical action of a spiral mixing shaft to shape materials, making it particularly suitable for organic raw materials with high moisture content. Flat die extrusion granulation uses the cooperation of a die and pressure rollers to extrude materials, requiring strict control over the moisture content of the raw materials. Rotary drum granulation uses the rotation of a drum to agglomerate materials, usually requiring a drying system. Raw Material Adaptability Comparison Raw material characteristics are the primary consideration when selecting granulation technology. Horizontal stirred extrusion granulation has the widest adaptability to raw materials, capable of directly processing organic materials with a moisture content of 25%-45%, including livestock and poultry manure, straw, mushroom residue, and various other organic wastes. This tolerance makes it an ideal choice for processing agricultural waste.
