With the rapid development of eco-agriculture, the resource utilization of agricultural and forestry wastes—such as livestock manure, crop straw, and mushroom residue—to produce organic fertilizer has become a core pathway for the green transformation of agriculture. As the central shaping equipment in organic fertilizer production lines, the disc granulator has become the preferred choice for facilities ranging from small-to-large processing plants and family farms to agricultural industrial parks. It offers advantages such as a simple structure, high adaptability, excellent granulation results, and outstanding cost-effectiveness, effectively solving industry pain points associated with powdered organic fertilizers, such as dust generation, storage and transport difficulties, and low utilization rates.
The disc granulator employs the principle of wet agglomeration granulation. By utilizing the centrifugal force generated by the rotating disc and the cohesive forces within the material, it allows fermented, decomposed powdered organic raw materials to naturally agglomerate and form granules during continuous rolling. Unlike high-pressure extrusion granulation processes, this gentle granulation method preserves the microbial activity within the organic matter and maximizes the fertilizer’s biological efficacy. This ensures the fertilizer effectively improves soil health and promotes plant growth while retaining nutrients, fully aligning with production standards for eco-friendly organic fertilizers.
The equipment boasts exceptional adaptability to raw materials, easily processing various organic substances such as fermented chicken manure, cattle manure, decomposed straw, mushroom residue, and sludge; stable production is achieved simply by adjusting the raw material moisture content to between 25% and 30%. It is user-friendly, reliable with a low failure rate, and easy to maintain. Requiring no complex setup, it allows operators to get up to speed quickly. Suitable for daily production capacities ranging from 1 to 10 tons, it meets the needs of both small-scale workshops and medium-sized processing plants.
In terms of product quality, the granules produced are round, uniform, and moderately hard. After drying and screening, they are dust-free and resistant to breakage, significantly enhancing the product’s visual appeal and market value. These uniform granules are ideal for mechanized application, allowing for precise dosage control and reduced waste, thereby effectively increasing fertilizer utilization rates across various agricultural settings, such as field crops and fruit or vegetable cultivation. Furthermore, the equipment’s open structure prevents material buildup and facilitates easy cleaning, enabling stable, continuous production while effectively reducing energy consumption and labor costs.
In summary, the disc granulator machine balances production efficiency, product quality, and production costs; it facilitates the efficient resource utilization of agricultural and forestry waste and drives the standardized, large-scale production of organic fertilizer. It is a core piece of equipment that empowers green agriculture, aids in the improvement of arable land, and enables the realization of an agricultural circular economy.
