Flat die extrusion granulator and flat disc granulator (usually referred to as disc granulator) play important roles in the production process of organic fertilizers, but there are significant differences in their working principles, scope of application, and product characteristics. The following is a specific comparison of the processes of two types of granulators:

working principle

Flat die extrusion granulator

Principle: The flat die extrusion granulator uses two sets of parallel arranged ring dies and pressure wheels to interact with each other, forcing the pre treated material into the die hole and extruding it under high pressure to form a continuous columnar material. When the columnar material leaves the mold hole, it will naturally fracture into particles of the required length due to the release of internal and external stress.

Characteristics: This type of machine is suitable for a variety of materials, especially for materials with certain hardness and adhesion, the effect is better. The high pressure during the granulation process helps to increase the density of particles, making them stronger and less prone to fragmentation.

Disc Pelletizer

Principle: The working basis of the disc granulator is to use the centrifugal force of the rotating disc to promote the rolling and aggregation of materials entering the disc in a moist state, gradually forming spherical particles. Under the frictional force on the inner wall of the disc, the material rolls along the inclined surface, and as the disc rotates, the particles continue to grow until they reach the desired size.

Characteristics: The particles prepared by the disc granulator are mostly approximately spherical, with a beautiful appearance and good flowability. It is more suitable for processing materials with certain viscosity and has certain requirements for the initial moisture content of the materials. Excessive or insufficient moisture content can affect the granulation effect.

Scope of application and product characteristics

Flat die extrusion granulator

Applicable materials: Suitable for most types of dry powder materials, including but not limited to organic fertilizers, biomass fuels, chemical raw materials, etc.

Product features: High granulation strength, regular particle shape, controllable size, suitable for long-distance transportation and mechanized application.

Disc Pelletizer

Applicable materials: mainly used for processing materials with certain humidity and bonding ability, such as animal manure, sludge, urban garbage and other organic waste.

Product features: The granulation process is mild and will not damage the active ingredients in the material. The produced particles have good solubility and are suitable for soil improvement and crop fertilization.

Fertilizers processed using organic fertilizer granulators (usually referring to organic fertilizers) and traditional chemical fertilizers (referred to as chemical fertilizers), although designed to supplement soil nutrients and promote crop growth, have multiple differences between them. These differences cover aspects such as source, composition, mechanism of action, environmental impact, and long-term effects:

Source and Composition

Chemical fertilizers:

Source: Mainly derived from industrial synthesis, prepared through chemical reactions.

Composition: Usually rich in one or several major nutrients such as nitrogen (N), phosphorus (P), and potassium (K). Common types include urea, potassium dihydrogen phosphate, potassium sulfate, etc.

Organic fertilizers:

Source: Organic substances derived from nature, such as animal manure, plant residues, kitchen waste, compost, etc.

Composition: In addition to N, P, and K, it also includes a large amount of organic matter, trace elements, and beneficial microorganisms, making its composition quite complex.

Nutrient release mode

Chemical fertilizers:

Rapid release: Nutrients in fertilizers are mainly inorganic and can quickly dissolve in water for immediate absorption and utilization by crops, but they can easily cause nutrient excess or loss.

Organic fertilizers:

Slow release: Nutrients in organic fertilizers are mostly encapsulated in organic compounds and need to be decomposed by microorganisms to gradually transform into forms that can be absorbed by crops. This process is slow but can last for a long time, helping to maintain the balance of soil nutrients.

Soil impact

Chemical fertilizers:

May damage soil structure, long-term extensive use can lead to soil compaction, pH imbalance, affect microbial activity, and be detrimental to soil health.

Organic fertilizers:

Promote the formation of soil aggregate structure, increase soil permeability and water retention capacity, improve soil physical properties, enrich soil biodiversity, and enhance soil self-healing and nutrient cycling capabilities.

Ecological and environmental impacts
