The functions and applications of the organic fertilizer double roller press granualtor are primarily reflected in the following aspects:

1. Granulation: Organic waste is fermented and pressed into fertilizer granules. The high-pressure zone between two counter-rotating rollers forces the material into a die, forming dense granules.

2. Energy-Saving and Environmentally Friendly: Granulation is achieved by directly utilizing the material's physical viscosity, eliminating the need for additional binders. This results in low energy consumption and zero exhaust emissions.

3. Stable Granule Quality: Organic fertilizer granules with high density, strength, and small size are produced. These granules not only have a regular appearance but also exhibit strong resistance to compression and fracture, making them easy to store and transport.

4. Uniform Granules with Adjustable Particle Size: Double-roller extrusion granulation produces a product with relatively uniform granules. The granule size can be controlled by adjusting the distance between the rollers to meet different market demands and usage requirements.

Applications

1. Recycling Livestock and Poultry Manure: Fermented chicken and pig manure can be directly granulated to produce commercial organic fertilizer.

2. Comprehensive Utilization of Straw: Mixed with livestock and poultry manure for granulation, improving the carbon-nitrogen ratio and fertilizer efficiency.

3. Sludge Treatment: Municipal or industrial organic sludge is treated and made into granular fertilizer.

4. Compound Fertilizer Production: Serves as the granulation step in organic-inorganic compound fertilizers, mixing and extruding with chemical fertilizers.

5. Other Industrial Applications: In addition to organic fertilizer production, this equipment can also be used to produce compound fertilizers and inorganic fertilizers of various concentrations and types. It can also be used in other industrial applications requiring granulation, such as capsule filling granules, pigments, and detergents.

Due to its high efficiency, low cost, and environmentally friendly characteristics, this equipment has become the preferred fertilizer equipment for large-scale organic fertilizer production, especially for small and medium-sized fertilizer processing plants.
