Double roller press granulators are widely used equipment in organic fertilizer production lines. They work by pressing powdered raw materials into granules using two counter-rotating rollers. Known for being efficient, energy-saving, and highly adaptable, they are essential in modern organic fertilizer production.

1.Suitable Types of Organic Fertilizer Production Lines
Manure-Based Organic Fertilizer Lines: Especially good for processing raw materials like chicken, pig, or cow manure, effectively pressing fermented manure powder into uniform granules.
Agricultural Waste Organic Fertilizer Lines: Suitable for granulating organic fertilizer made from agricultural waste like straw, rice husks, or wood chips. They handle this material well.
Municipal Sludge Organic Fertilizer Lines: Can press treated municipal sewage sludge mixed with additives into granular fertilizer.
Compound Organic Fertilizer Lines: Suitable for producing organic-inorganic compound fertilizers, allowing the addition of various trace elements and functional ingredients.
Bio-Organic Fertilizer Lines: Suitable for granulating organic fertilizers containing beneficial microbial agents. The low-temperature extrusion process doesn’t harm the microbes.

2.Points to Consider When Choosing a Double Roller Press Granulator
When selecting this type of granulator, consider factors like the material properties, required output, and desired granule size. It’s recommended to choose the right model and setup based on your specific production needs to ensure the best efficiency and product quality.

In summary, with their excellent performance and wide applicability, double roller press granulators provide organic fertilizer producers with an efficient and cost-effective granulation solution.
