Raghad Mouhamad

You can manually synthesize urea-calcium carbonate granules using a straightforward method. Here’s a simple procedure:

Materials Needed:Urea: A nitrogen-containing compound widely used as a fertilizer. Calcium Carbonate (CaCO₃): Commonly found in limestone or chalk. Water: For mixing and granulation. Mixing Container: A vessel to combine the ingredients. Granulation Equipment: A simple tool for forming granules (e.g., mortar and pestle).

Procedure: Weigh the Ingredients:Measure the desired amounts of urea and calcium carbonate. The ratio depends on your specific application (e.g., fertilizer formulation). Mix the Ingredients:Combine urea and calcium carbonate in the mixing container. Use a mortar and pestle or any suitable tool to ensure thorough mixing. Add Water:Gradually add water to the mixture. Stir continuously until you achieve a uniform paste-like consistency. Form Granules:Shape the mixture into small granules using your hands or a spoon. Alternatively, use a simple granulation device to form consistent-sized granules. Drying:Place the granules in a well-ventilated area to dry. Ensure they are completely dry before storage or use.

Quality Control:Test the granules for hardness, size, and uniformity. Adjust the formulation or process if needed.

Storage:Store the urea-calcium carbonate granules in a dry container. Protect them from moisture and direct sunlight.

Remember that this manual method provides basic granules. For large-scale production or specific applications, consider industrial processes and specialized equipment. Always follow safety precautions when handling chemicals.

First calcium carbonate and binding agent are directly added in granulator, then after water filling granulates, dry, screening, mixed processes. Combine urea and calcium carbonate in the mixing container. Use a mortar and pestle or any suitable tool to ensure thorough mixing. Add Water: Gradually add water to the mixture. Stir continuously until you achieve a uniform paste-like consistency.

Paul Milham

Hi Raghad and Prem, How much decomposition to ammonium carbonate and NH3 volatilisation occurs in the suggested processes? Regards, Paul

Balaganesh B.

Raghad Mouhamad and Prem Baboo when we are adding water during the process of making paste like consistency the N content could be decreased. Then it wouldn't have an fertilizer value right?
