By : root
A compound fertilizer extrusion granulation production line is a set of industrial equipment and processes designed to manufacture compound fertilizers through an extrusion granulation method. It transforms raw materials rich in nitrogen (N), phosphorus (P), and potassium (K) into uniformly granulated fertilizer products, which are easier to apply, store, and transport compared to powdery fertilizers. This production line is widely used in the chemical fertilizer industry to meet the growing demand for high-efficiency, environmentally friendly fertilizers that improve soil fertility and crop yields.
Compound Fertilizer Extrusion Granulation Production Line Core Components of the Production Line
The production line consists of several key equipment units, each responsible for a specific stage of the granulation process:
Raw Material Preparation Equipment:
Mixers (e.g., double-shaft mixers): Ensure thorough blending of N, P, and K raw materials (such as urea, diammonium phosphate, potassium chloride) and additives (e.g., fillers, binders) to achieve a uniform composition.
Crushers (e.g., hammer crushers): Reduce the particle size of large raw materials to a suitable size for subsequent granulation.
Extrusion Granulation Equipment:
Extrusion granulators (e.g., roll-type extrusion granulators): The core device that uses mechanical pressure to compress the mixed raw materials into granules. These granulators typically feature two counter-rotating rolls with mold holes; the materials are forced into the holes under pressure to form granules.
Post-Granulation Processing Equipment:
Dryers (e.g., rotary drum dryers): Remove excess moisture from the wet granules to achieve a specified moisture content (usually below 2%).
Coolers (e.g., rotary drum coolers): Cool the hot granules to room temperature to prevent caking during storage.
Screening machines (e.g., drum screens): Separate the granules by size, with undersized granules recycled back into the granulation process and oversized granules crushed and reused.
Packaging and Auxiliary Equipment:
Packaging machines (e.g., automatic weighing and packaging machines): Weigh and package the qualified granules into bags.
Dust collectors and exhaust systems: Control dust and emissions to meet environmental protection standards.
Compound Fertilizer Extrusion Granulation Production Line Key Technical Features
Dry Granulation Process: Unlike traditional granulation methods that require steam or liquid binders, extrusion granulation is a dry process, reducing energy consumption and avoiding issues like material caking.
High Granulation Efficiency: The extrusion process can achieve a granulation rate of over 90%, with granule sizes precisely controlled (typically 2–4 mm).
Wide Raw Material Adaptability: Suitable for various raw materials, including high-nitrogen, high-potassium, and low-moisture materials, without strict requirements for material moisture content.
Energy Saving and Environmental Protection: Low energy consumption and minimal emissions, aligning with the development trends of green and sustainable agriculture.
High Automation: Equipped with automated control systems for precise control of material ratios, granulation pressure, and temperature, reducing manual intervention.
Compound Fertilizer Extrusion Granulation Production Line Production Process Flow
The production process follows a strict sequence to ensure product quality and efficiency:
Raw Material Preparation: Blend and crush the N, P, and K raw materials and additives to achieve a uniform mixture.
Extrusion Granulation: Feed the mixed materials into the extrusion granulator to form granules under mechanical pressure.
Drying and Cooling: Dry the wet granules to remove moisture and cool them to room temperature to stabilize the granules.
Screening and Recycling: Screen the granules by size, with unqualified granules recycled back into the granulation process.
Packaging: Weigh and package the qualified granules into bags for storage and transportation.
