The roller extrusion granulator is a very effective granulation equipment in organic fertilizer production, especially suitable for producing granular organic fertilizers and organic-inorganic compound fertilizers. This granulator compresses the material into the desired particle shape through two sets of relatively rotating rollers. The following are several key advantages of using a roller extrusion granulator to produce organic fertilizers:
Wide applicability: The roller extrusion granulator can process various organic materials, such as livestock manure, crop straw, urban organic waste, as well as organic-inorganic mixed materials, with high applicability and flexibility.
High particle strength: By adjusting the pressure of the rollers, particles with high mechanical strength can be produced, which helps to maintain their integrity during transportation and storage, reducing breakage and dust generation.
Controllable particle shape: The roller extrusion granulator can produce regular and uniform particles. By changing the shape and size of the rollers, the size and shape of the particles can be adjusted to meet different fertilizer specifications.
Low energy consumption: Compared to other types of granulators, roller extrusion granulators have lower energy consumption because they mainly rely on the weight of materials and mechanical extrusion force, reducing their dependence on thermal energy and lowering production costs.
Good environmental friendliness: During the production process, the roller extrusion granulator produces less dust and exhaust gas, which helps reduce the impact on the environment and meets the requirements of environmentally friendly production.
High degree of automation: Modern roll extrusion granulators are usually equipped with automatic control systems, which can achieve continuous feeding of materials, automatic adjustment of pressure, automatic screening and collection of particles, improving production efficiency and stability of product quality.
When using a roller extrusion granulator to produce organic fertilizers, attention should be paid to the pretreatment of raw materials, such as appropriate crushing, mixing, and humidity adjustment, to ensure the smooth progress of the granulation process. In addition, according to different production needs and raw material characteristics, it may be necessary to configure appropriate auxiliary equipment, such as raw material crushers, mixers, screening machines, dryers, etc., to form a complete organic fertilizer production line.
