Pig manure is characterized by its wet, sticky consistency and high nitrogen content, making it prone to clumping; when processed in isolation, it often presents challenges such as uneven composting and difficulties in granulation. By operating in tandem, the double screws compost turning machine and the rotary drum granulator effectively resolve these critical issues, making this integrated system ideally suited for small-to-medium-scale pig manure resource utilization scenarios.
The double screws compost turning machine handles the front-end pretreatment phase. It breaks up pig manure clumps, thoroughly mixes the manure with carbon-rich materials—such as straw and sawdust—to optimize the carbon-to-nitrogen ratio, and accelerates the composting process. This prepares the material for granulation and effectively prevents adhesion issues during the subsequent pelletizing stage.
The rotary drum granulator takes charge of the back-end molding process. It processes the pretreated pig manure feedstock, rapidly transforming it into organic fertilizer granules of uniform size and optimal hardness. This resolves the issues of granule looseness or clumping often encountered in standalone granulation processes, thereby significantly enhancing the aesthetic quality and market appeal of the final product.
The key to the synergy between these two machines lies in their synchronized operational rhythm: the double screws compost turning machine precisely controls the degree of composting and moisture content of the feedstock, while the rotary drum granulator matches this output with its processing capacity. This ensures a stable and continuous supply of raw materials, effectively preventing nutrient loss or granulation failures.
In summary, the combined operation of the double screws compost turning machine and the rotary drum granulator enables the highly efficient processing of pig manure. With minimal operational complexity, this integrated system facilitates the effective resource utilization of pig manure, yielding high-quality granular organic fertilizer.
