The Art of Granulating Charcoal-Based Fertilizer Using a Roller Granulator

Charcoal’s application in agriculture has grown significantly over the years, thanks to its beneficial properties. Charcoal-based fertilizers are efficient in moisture retention, enhancing soil fertility, and mitigating greenhouse gas emissions. Production of charcoal-based fertilizer granules requires a robust and efficient granulation process, ideally achieved with a roller granulator. So if you want to read more information, you can visit to my web:

A double roller granulator, also known as a roll press granulator, is a crucial tool in the granulation process of fertilizers. It uses the extrusion force and friction force from its rollers to make powder material into granules. This article explains a step-by-step guide on how to manufacture charcoal-based fertilizer granules using a roller granulator.

Raw Material Preparation:

The first step involves preparing the charcoal by crushing it into a powder form. Other materials to enhance the fertilizer’s nutrient content, such as nitrogen, phosphorus, and potassium sources, should also be ground into a fine powder. The ratio of these materials will differ depending on the desired final product’s nutrient requirements.


Once the raw materials are ready, mix them thoroughly to achieve a uniform composition. High-quality granules are a result of a consistent mixture.

Feeding the Double Roller Granulator:

The next step is to feed the mixture into the double roller machine. The machine features a hopper that receives the mixture. An adjustable speed motor drives the hopper to ensure a steady flow of the material into the granulator.

Granulation Process:

The crux of the granulation process lies in the extrusion and pressing of the raw material. The roller granulator uses its two rollers to compress the powder, creating enough pressure to form granules. The gap between the rollers determines the size of the granules. Therefore, depending on your desired granule size, you can adjust the gap accordingly.


After the granulation process, the next step is to separate the formed granules from the excess powder. This separation is done through a screening process. The granules are sieved, and any ungranulated materials are returned to the hopper for regranulation.

Drying and Cooling:

The granules are then dried to reduce their moisture content, enhancing their stability. After drying, the granules are cooled to room temperature.

Coating and Packaging:

To improve the granules’ aesthetic appearance and resist moisture, a coating is usually applied. Finally, the granulated charcoal-based fertilizer is packaged ready for sale or use.

The roller granulator presents a simple, efficient and cost-effective way to produce high-quality charcoal-based fertilizer granules. It allows for the control of granule size, is energy-efficient, and ensures a high granulation rate. Understanding the process, as outlined above, is key to optimizing the granulation process.

The application of charcoal-based fertilizer benefits not only the plants but also the environment. Therefore, mastering the production process is a stride towards sustainable farming.
