Building a perfect Organic Fertilizer Production Line is an effective way to realize the rapid decomposition and high-quality transformation of cattle manure. The production line integrates raw material pretreatment, mixing ratio, high temperature fermentation, granulation molding, drying and cooling, screening and packaging and other links, forming a closed-loop circular economy system. In this system, cow manure is scientifically proportionally mixed with carbon-rich organic materials such as straw, leaves, and vegetable residues to create optimal conditions for microbial activity by precisely controlling the C/N ratio.
