Hou to Make Granular fertilizer by Drum Granulation Machine?

Granular fertilizer is a type of fertilizer that is made into small, granular particles, which makes it easier to store, transport, and apply to crops. Granular fertilizer is preferred over other forms of fertilizers because of its slow-release nature, which ensures that the nutrients are released slowly to the plants over time, thereby preventing nutrient leaching and soil erosion. Granular fertilizers are also more efficient and cost-effective than other forms of fertilizers.In this article, we will guide you through the process of making granular fertilizer by drum granulation machine, from selecting the appropriate fertilizer ingredients to operating the drum granulator.

Drum Granulation Machine

One of the most popular methods of making granular fertilizer is by using a drum granulation machine. This machine is used to create round granules by agglomerating materials together in a drum. The drum rotates, and the materials are mixed and coated with a binder to form granules. The granules are then dried and cooled to make them more stable and long-lasting.

Selecting the Appropriate Fertilizer Ingredients

The first step in making granular fertilizer by drum granulation machine is selecting the appropriate fertilizer ingredients. The type of fertilizer you want to produce will dictate the ingredients you will need. For example, if you want to produce a nitrogen-based fertilizer, you will need to use a source of nitrogen, such as ammonium sulfate, urea, or ammonium nitrate. If you want to produce a phosphorous-based fertilizer, you will need to use a source of phosphorous, such as rock phosphate or triple superphosphate. Similarly, if you want to produce a potassium-based fertilizer, you will need to use a source of potassium, such as potassium chloride or potassium sulfate.

Preparing the Ingredients

Once you have selected your fertilizer ingredients, the next step is to prepare them for granulation. This involves grinding the ingredients into a fine powder and mixing them together in the appropriate proportions. The proportions will depend on the specific fertilizer formula you are using, and can be adjusted based on the nutrient requirements of your target crop.

Adding the Liquid Binder

After the ingredients have been prepared, the next step is to add the liquid binder. The binder is typically a solution of water and a binding agent, such as clay or starch. The binder is added to the drum granulator through a spray system, which evenly distributes the liquid across the surface of the fertilizer particles. The binder helps the particles stick together, forming granules of the desired size.

Granulating the Fertilizer

Once the liquid binder has been added, the drum granulation machine is activated, and the granulation process begins. The drum rotates, causing the fertilizer particles to collide and stick together. As the granules grow in size, they are continuously sprayed with the liquid binder to help them maintain their shape.

Drying and Cooling the Granules

After the granulation process is complete, the granules are dried and cooled to ensure that they are stable and free-flowing. The drying process is typically accomplished by passing the granules through a hot air stream, while the cooling process is accomplished by passing them through a cooler air stream. The final product is a uniform, free-flowing granular fertilizer that is ready for packaging and distribution.

In conclusion, making granular fertilizer by drum granulation machine is a straightforward process that requires careful selection of ingredients, preparation of the ingredients, addition of the liquid binder, granulation, and drying and cooling of the granules. With the right equipment and knowledge, anyone can produce high-quality granular fertilizer that provides essential nutrients to plants and helps improve crop yields.
