Prilled or Granular Urea for Fertilizer Blending

If you buy urea for fertilizer blending, match the particle form to your blend and handling system.

Relia's prilled or granular proposals can be reviewed for nitrogen, biuret, moisture and size distribution.

From Your Requirement to a Defined Grade

Relia manufactures urea materials in China through its own factories.

Our urea enquiry should identify the required physical form and the other components in your blend. Give us the accepted nutrient, biuret, moisture and particle limits. The proposal should remain explicit about prilled or granular material before your team compares its behaviour through the actual handling and blending cycle.

The Blending Requirement

The urea catalogue descriptions state 46% nitrogen and include prilled or granular enquiries. This is a nutrient basis, not 46% chemical purity. We identify the offered form and relevant physical limits before discussing a shipment for blending, handling or other agricultural-fertilizer requirements.

Your trial and acceptance

A Relevant Handling Comparison

Compare the offered form against the actual handling and finished-fertilizer requirements. Keep particle distribution, fines and relevant physical tests with the nutrient record. Prills and granules can require different handling assessments, so a shared 46% nitrogen headline is not a complete substitute specification.

Manufacturing and grade controls

Solution Synthesis Through to Prills or Granules

Urea solution is concentrated and formed into solids by prilling or granulation, followed by the finishing required for that product. Size distribution, fines and mechanical condition are therefore separate from nitrogen analysis. Connect the offered physical data with your blend's size match and handling observations rather than using particle diameter alone to predict performance.

  1. Create the urea solution

    Industrial synthesis uses ammonia and carbon dioxide, followed by recovery and concentration stages.

  2. Form the solids

    Prilling and granulation create different physical product proposals.

  3. Cool and classify

    Finishing and size separation influence fines and the fraction presented to the blending plant.

  4. Retain the physical grade

    Keep particle and condition data with nitrogen, moisture and biuret requirements.

Nutrients
Nitrogen content and compound purity are different descriptions.
Particles
Compare the actual size distribution and condition rather than diameter alone.
Blending
Match the offered form with the other components and the handling cycle.
Keep the proposed grade's production route and measured acceptance limits together in the material specification.

From sample to supply

A Defined Shipment Proposal

Retain the approved form and analysis with the proposed grade. We discuss packing and supply conditions against that record. Changes in particle distribution or material condition can then be checked against your acceptance limits.
