Full Production Process: A complete bio-organic fertilizer production line typically includes seven core processes: fermentation → crushing → granulation → drying → screening → coating → packaging. Each step is closely integrated to complete the transformation from organic waste to commercial organic fertilizer. Fermentation: Using livestock manure, straw, sludge, etc., as raw...

Common Types and Characteristics Organic fertilizer granulators are key equipment for turning fermented and decomposed powdery materials into granules. Based on different process principles, there are three main types: Disc Granulator:Simple in structure, consisting of an inclined disc and a scraper. The material rolls within the disc to form granules, achieving a granulation rate of 70%-85%...

Microbial succession during fermentation The aerobic fermentation of bio-organic fertilizer is not the action of a single microorganism, but a complex process of microbial community succession. Different temperature stages are dominated by different groups of microorganisms: In the low-temperature stage (ambient temperature to 40℃), psychrophilic bacteria and some mesophilic bacteria (such as...

Calculation Characteristics of BB Fertilizer Formulation Blended fertilizers (BB fertilizers) are made by directly mixing nitrogen, phosphorus, and potassium granules in a specific ratio without chemical granulation. Their formulation calculation is similar to that of compound fertilizers, but there are two significant differences: First, BB fertilizer raw materials retain their original particle...

 Comparison of the Two Granulation Processes In organic fertilizer production, wet granulation and dry granulation are two mainstream technologies. Wet granulation, represented by disc and drum granulators, requires water or steam to assist in pellet formation and necessitates a subsequent drying process. Dry granulation, centered on roller extrusion, relies on high pressure for direct...

Working Principle of Disc Granulators Disc granulators, also known as disc granulators or inclined disc granulators, are among the oldest and simplest granulation equipment used in the fertilizer industry. Their core component is a large-diameter circular steel disc, driven by a motor and reducer to rotate around a central axis. The disc surface is inclined at an angle of 40° to 55° to...

Needs Research: The First Step in Customization The core of a customized organic fertilizer production line lies in “tailor-made” solutions—the production line scale, equipment configuration, and process route should all revolve around the user’s specific needs. Before designing the solution, at least three basic questions need to be clarified: How much raw material is processed daily...

Core Functions of Turning: In aerobic composting, turning is not simply moving materials; it performs four key functions: Oxygen Supply—bringing air into the compost pile to maintain the activity of aerobic microorganisms; Temperature Regulation—breaking up high-temperature areas and preventing local temperatures exceeding 70°C from killing the microorganisms; Moisture Removal—evaporating excess...

The Root Cause of Uneven Nutrient Distribution NPK blended fertilizer is the simplest type of compound fertilizer—it’s made by directly mixing basic nitrogen, phosphorus, and potassium granules. However, this “simplicity” brings a core challenge: nutrient stratification. Heavier particles (such as some phosphate fertilizers) tend to settle at the bottom, while smaller particles...

 Hard fertilizer particles, such as monoammonium, diammonium, and urea, are common challenges in organic and compound fertilizer production. A high-quality cage crusher is essential to crush these hard materials into uniform powder, ensuring smooth subsequent granulation and improving overall production efficiency. However, selecting the right cage crusher for hard fertilizer particles...
