Essential Differences Between the Two Technologies: Disc granulation production lines use a wet process, rolling materials into pellets within a disc using water or steam. Subsequent drying and cooling equipment is required to remove moisture. Roller extrusion production lines, on the other hand, use a dry process, directly pressing powder into flakes under high pressure, followed by...

Factors Determining Mixing Uniformity In organic fertilizer production, mixing uniformity directly affects fermentation efficiency, granulation effect, and the nutrient consistency of the final product. Horizontal mixers are currently one of the most widely used mixing equipment in the organic fertilizer industry. They employ a U-shaped cylinder with an inner and outer double-layer spiral ribbon...

What is a Hydraulic Compost Turner? A hydraulic compost turner is a core piece of equipment in aerobic composting processes, primarily used for fermenting and turning organic waste such as livestock and poultry manure, sludge, and straw sawdust. The biggest difference between it and ordinary compost turners is its hydraulic lifting system, which allows for flexible adjustment of the...

Compactor Structure and Working Process A fertilizer compactor is a core piece of equipment specifically designed for dry granulation. Its working principle is similar to that of a roller extrusion granulator, but its structure places greater emphasis on continuous and stable operation and high-volume adaptability. A typical fertilizer compactor mainly consists of the following parts:...

Efficiency is Not a Single Choice When choosing granulation equipment, “which is more efficient?” is the most common question users ask. However, efficiency is not a single indicator—it includes both “explicit efficiency” such as single-machine output and pelletizing rate, and “implicit efficiency” such as energy consumption, return on investment, and...

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...
