In the production line of organic fertilizer from cow manure, the fertilizer granulator is an important post-treatment equipment used to process fermented organic fertilizer raw materials into regular particles, in order to improve the appearance quality and application convenience of the fertilizer. The following are several commonly used types of fertilizer granulators, each with its own characteristics and suitable for different production needs:
The disc granulator is one of the most common organic fertilizer granulation equipment, which gradually rolls the material on the rotating disc into spherical particles under centrifugal force. This machine is easy to operate, compact in structure, and suitable for small and medium-sized production scales.
2. Extrusion granulator
The extrusion granulator uses pressure to extrude loose materials into compact cylindrical or strip-shaped particles, which are then cut into the desired length. Suitable for handling high viscosity materials, such as organic fertilizer mixtures that have been moderately humidified.
3. Efficient rotary drum granulator
The efficient rotary drum granulator utilizes a rotating drum body to roll and gradually shape the material into particles. This granulator has high granulation efficiency, is suitable for large-scale production, and can produce high-quality granular fertilizers.
4. Flat mold granulator
The flat mold granulator uses the principle of mold extrusion to extrude raw materials from the template holes into particles, which are suitable for processing various organic fertilizers, especially for materials with hard and solid texture, and have good effects.
5. Ball milling granulator
The particles produced by ball milling granulators have a smooth surface, high hardness, and strong durability. Suitable for situations where there are certain requirements for particle shape and strength.
6. Double axis kneading and granulation machin
The dual axis mixing and granulation machine integrates the mixing and granulation processes, making it particularly suitable for the granulation of organic fertilizers with complex material compositions. It can effectively improve the uniformity and stability of particles.
Principle of selection
When choosing a granulator in a cow manure organic fertilizer production line, the following aspects should be considered:
Raw material characteristics: Different raw material characteristics (such as moisture content and adhesion) can affect the effectiveness of granulation and the applicability of equipment.
Production scale: Whether to produce in small or large quantities determines the equipment’s production capacity and degree of automation.
Particle requirements: Are there any special requirements for particle size, shape, and hardness?
Cost effectiveness: Consider the initial investment and operating costs of the equipment, and find the most cost-effective solution.
in summary
Each type of granulator has its own advantages, disadvantages, and optimal application scenarios, so when choosing, one should carefully evaluate their own production conditions and goals. If necessary, professional equipment suppliers can be consulted to find the most suitable equipment for their production line.
