First, lets discuss the advantages and disadvantages of each granulator, so that everyone can make comparisons when purchasing granulators or fertilizer equipment in the future.

Detailed Explanation of the Roller Granulator:

The rotary drum granulator belongs to the dry granulation method, which eliminates the drying process. It produces granules with high density, excellent fertilizer efficacy, and minimal nutrient loss. This method saves the cost of purchasing dryers and coolers, and eliminates the need for coal burning in later stages, resulting in significant cost savings. In contrast, the extrusion granulator produces flatter granules, which are prone to jamming when sown with field crop machinery and exhibit poor flowability. Therefore, farmers should exercise caution when producing fertilizers with this method and are advised to opt for compound fertilizers instead.

Advantages of the rotary drum granulator:

The energy-saving and consumption-reducing roller extrusion granulator utilizes raw materials for production at room temperature, thereby reducing drying energy consumption.

2. By utilizing the intermolecular forces of raw materials, the granulation process is simplified, reducing the consumption of additives and energy.

Rotary drum granulator

The rotary granulator is a compound fertilizer granulation process, which can also be used for chemical fertilizer production but has a relatively low granulation rate.

Disc Granulator

The disc pelletizer is a relatively traditional granulation process. Personally, I advocate for this type of pelletizer, as it ensures smooth granulation, enjoys good sales, and has low equipment costs. However, its drawback is low density. Currently, people are pursuing new granulation methods, and its user base is dwindling.
