Pig manure is an excellent raw material for organic fertilizer due to its high organic matter content and balanced nutrients; however, processing it presents common challenges such as high moisture content, a sticky texture, and a tendency to clump. To address these material characteristics, the pig manure disc granulation production line employs a specialized process that effectively resolves key processing hurdles, enabling the harmless treatment of pig manure and the standardized mass production of granular organic fertilizer—a proven solution for the resource recycling of livestock waste.
The entire fertilizer production line utilizes a segmented processing workflow tailored to the specific properties of pig manure. Initial stages involve pre-treatment equipment to dewater and break up the manure, precisely controlling moisture levels and eliminating clumping to fundamentally solve issues with material sticking to equipment walls or resisting granulation. Concurrently, windrow turning equipment ensures thorough composting, completely eliminating pathogens and parasite eggs while removing odors, thereby ensuring the raw material meets safety standards.
At the core of the process, the disc granulator employs an ambient-temperature agglomeration technique; composted powder naturally forms into granules through the centrifugal force of the rotating disc, preserving nutrient integrity throughout. The resulting granules are uniform in size and shape. By adjusting the equipment’s rotation speed and tilt angle, the system flexibly accommodates various formulas and particle size requirements, demonstrating exceptional versatility.
The downstream section of the line integrates drying, screening, and packaging equipment to create a complete, closed-loop production system. Substandard granules can be recycled for further processing, significantly reducing raw material waste. The entire system features a high degree of automation and stable operation, meeting the needs of both medium-to-large-scale mass production and flexible, multi-formula manufacturing.
The pig manure organic fertilizer produced by this line offers a mild, long-lasting fertilizing effect; it effectively alleviates soil compaction and revitalizes soil fertility. Suitable for a wide range of applications—including grain crops and fruit and vegetable cultivation—it truly realizes the resource-efficient and eco-friendly utilization of livestock waste.
