In the field of organic fertilizer production, the organic fertilizer disc granulation production line, with its simple and efficient granulation method, can process organic materials from various sources. Which materials is this production line suitable for processing? The key lies in whether the viscosity, fiber content, and moisture content of the raw material match the disc granulation process.
1.Livestock and Poultry Manure
This is the most common material processed by disc granulators. Fully decomposed chicken manure, pig manure, cow manure, etc., undergo partial degradation of cellulose during fermentation, forming a loose material with a certain degree of viscoelasticity. Chicken manure, in particular, usually produces ideal granulation results due to its high content of coarse fiber and undigested substances.
2.Agricultural Waste
Straw powder, rice husk charcoal, mushroom residue, tobacco dust, and other agricultural byproducts are also suitable raw materials for disc granulation. These materials often have a high fiber content and insufficient binding force when granulated alone, usually requiring combination with livestock and poultry manure or a small amount of binder.
3.Industrial By-products
Organic industrial waste such as sugar factory filter mud, distiller’s grains, soybean residue, and traditional Chinese medicine residue are commonly found in organic fertilizer disc granulation production lines. These materials typically have high moisture content and a fine texture, requiring dehydration or drying to adjust to a suitable moisture content before entering the discs.
4.Municipal Waste
Sludge that has undergone harmless treatment and fermented kitchen waste can also be transformed into resources on disc granulation lines. These materials require strict compliance with decomposition standards and heavy metal regulations, and are usually mixed with conditioners such as straw powder to adjust their physical properties for successful granulation in the discs.
5.Mixed Materials and Functional Additives
Disc granulation also allows for the flexible addition of functional components. Biochar, functional microbial agents, and trace elements can be evenly mixed into the organic fertilizer base, achieving simultaneous granulation and loading through the rolling of the discs.
