In organic fertilizer production lines, rotary drum granulators are key equipment determining product formation rate and quality. Due to their high adaptability to the characteristics of organic fertilizer raw materials, they are the preferred choice of many manufacturers.

Organic fertilizer raw materials, such as livestock and poultry manure and composted straw, are high in moisture and complex in composition. Traditional granulation equipment is prone to problems such as sticking to the wall and uneven granulation. However, a rotary drum granulator utilizes an inclined rotating drum structure. Once the mixed raw materials enter the drum, the low-speed centrifugal force, friction, and gravity combine to gradually aggregate the raw materials into spherical granules. This process eliminates the need for strong compression and perfectly adapts to the soft physical properties of organic fertilizer. The granulation rate can reach over 90%, and the resulting granules are round and moderately strong, making them easy to dry and package.
Other advantages include production efficiency and flexibility. The rotary drum granulator's processing capacity can be adjusted to meet production line needs, ranging from a few tons to tens of tons per hour, accommodating operations ranging from small workshops to large factories. Furthermore, by adjusting the drum speed, inclination angle, and moisture content of the raw materials, the particle size (typically between 2 and 6 mm) can be precisely controlled to meet fertilizer requirements for various applications, such as fruit and vegetable cultivation and field crops.
In actual production, rotary drum granulators can seamlessly integrate with pre-fermentation and post-drying equipment to form a continuous production process. For example, after introducing a rotary drum granulator, an organic fertilizer plant saw its daily production line output increase by 30% and reduced the granule breakage rate from 15% to below 5%, significantly reducing raw material waste and production costs. Furthermore, the equipment's enclosed design effectively reduces dust emission, and its integrated exhaust gas treatment system complies with environmental protection policies for green organic fertilizer production.
Today, with the advancement of green agricultural development, demand for organic fertilizer continues to grow. With its high efficiency, stability, and environmentally friendly advantages, rotary drum granulators are becoming a key force in promoting the large-scale and standardized development of the organic fertilizer industry, providing solid technical support for the resource utilization of agricultural waste and the improvement of soil fertility.
