Granulation of Livestock and Poultry Manure Organic Fertilizer: Key Technologies and Quality Control
Livestock and poultry manure is the primary raw material in organic fertilizer production. However, chicken manure, cow manure, and pig manure have significantly different physicochemical properties, posing different requirements for granulation processes. Chicken manure has a high nitrogen content and is prone to moisture absorption and clumping; cow manure has coarse and long fibers and requires fine crushing; pig manure is highly viscous and easily sticks to equipment. Mastering granulation technologies for different types of manure is crucial for ensuring pellet quality and improving production efficiency.
