Core requirements for materials processed by the new type two in one organic fertilizer granulator

by organic fertilizer production line

While the new type two in one organic fertilizer granulator simplifies the organic fertilizer production process with its integrated design, it has more specific requirements regarding the adaptability of the processed materials.

Precise control of material particle size is crucial. Raw materials entering the new type two in one organic fertilizer granulator must undergo crushing and screening to ensure uniform particle size controlled within the 1-3 mm range. Large impurities or incompletely crushed lumps in the material will not only clog the equipment’s feed channel and die holes but may also accelerate the wear of internal components, affecting granulation continuity. Excessively fine powdery materials are prone to generating dust and will result in insufficient granule strength after molding.

Material moisture control is critical. The suitable material moisture content is 20%-30%, which needs to be fine-tuned based on the raw material composition. Excessive moisture content causes the material to easily clump together inside the machine, leading to a decrease in granulation rate and potentially causing die blockage. Insufficient moisture content results in a lack of viscosity, making it difficult to form through extrusion or granulation processes, and even if formed, it is prone to breakage.

The material composition ratio must be scientific. The carbon-to-nitrogen ratio of the raw materials should be maintained at 25-30:1. Avoid imbalances in the proportion of single high-nitrogen raw materials (such as poultry and livestock manure) or high-carbon raw materials (such as straw), otherwise the stability of the fertilizer effect after pelleting will be affected. At the same time, the proportion of fiber components in the material should not be too high. Excessive fiber can easily entangle equipment parts, requiring pretreatment to decompose some coarse fibers. If the raw material lacks viscosity, a suitable amount of natural binder can be added to improve the pelleting effect.

Furthermore, the material must be fully decomposed. Undecomposed raw materials may undergo secondary fermentation after granulation in the new type two in one organic fertilizer granulator, causing the pellets to expand and break, and potentially leading to seedling burn during fertilization.

What is the fertilizer production process?

by organic fertilizer production line

Introduction

Fertilizer production is a crucial process in modern agriculture, providing essential nutrients for crop growth worldwide. Understanding the manufacturing processes of NPK compound fertilizers and nitrogen fertilizers like urea helps appreciate the complexity behind agricultural productivity. This article explores both industrial-scale and laboratory methods for producing these vital agricultural inputs.

NPK Compound Fertilizer Production

Industrial Manufacturing Process

The industrial production of NPK fertilizers follows a systematic approach to ensure consistent quality and nutrient content:

· Raw Material Selection and Preparation: Manufacturers select nitrogen sources (urea, ammonium chloride), phosphorus sources (monoammonium phosphate, diammonium phosphate), and potassium sources (potassium chloride, potassium sulfate). These materials are ground to 80-100 mesh and purified to remove impurities.

· Proportioning and Mixing: Ingredients are precisely measured according to target nutrient ratios (such as 15-15-15) and mixed thoroughly in industrial mixers. Small amounts of binders like bentonite are added to improve granule formation.

· Granulation: Two main methods are employed: rotary drum granulation, where mixed powder is fed into a rotating drum and moistened with steam or water to form granules through agglomeration; and spray granulation, where some raw materials are dissolved into slurry and sprayed onto recycled particles to build up granules layer by layer.

· Drying and Cooling: Granules enter dryers with hot air temperatures of 120-180°C to reduce moisture content to ≤2%, followed by cooling to room temperature to prevent caking.

· Screening and Packaging: Vibrating screens separate granules by size, with off-spec particles crushed and returned to the process. Qualified granules receive anti-caking treatments (such as talc coating) before being weighed and packaged.

Laboratory/Small-Scale Preparation

For research or small-scale applications, simplified methods can produce NPK fertilizers:

· Raw Material Preparation: Analytical grade urea, potassium dihydrogen phosphate, and ammonium sulfate are selected, ground, and sieved through 100-mesh screens.

· Proportioning and Mixing: Materials are weighed according to designed nutrient ratios and mixed in a mortar or small mixer with anhydrous ethanol as a binder.

· Forming and Drying: The mixture is compressed into tablets using a tablet press, then crushed and sieved to desired particle sizes, or manually shaped into granules. Drying occurs in an oven at 60°C for 2-4 hours.

· Product Testing: Final products are analyzed for nutrient content, crushing strength, and solubility, with adjustments made to formulations or binder amounts as needed.

Nitrogen Fertilizer (Urea) Production

Urea manufacturing involves sophisticated chemical processes at industrial scale:

· Ammonia Synthesis: Using natural gas or coal as raw materials, high-purity hydrogen and nitrogen are produced through processes including gasification, desulfurization, shift conversion, decarbonization, and methanation. Ammonia (NH₃) is synthesized under high temperature and pressure (300-500°C, 10-30 MPa) with catalysts.

· Reaction with Carbon Dioxide: Ammonia and carbon dioxide are fed into synthesis reactors at 180-200°C and 13-20 MPa pressure to form ammonium carbamate.

· Dehydration to Urea: Ammonium carbamate undergoes dehydration in decomposition towers, converting to urea and water. The reaction follows: 2NH₃ + CO₂ → NH₂COONH₄ → CO(NH₂)₂ + H₂O.

· Purification and Drying: Water is removed through evaporation and concentration, followed by crystallization, centrifugal separation, and drying to produce final urea product with purity exceeding 99.5%.

Global Significance

These production processes have revolutionized global agriculture by making essential nutrients widely available. The scalability from laboratory to industrial production allows for continuous innovation in fertilizer formulations while maintaining quality control.
