Drum granulators, with their unique advantages, have become core equipment for many companies in the pellet production process of industries like fertilizer, feed, and minerals. Based on a drum-type structure, they produce granules by rolling and agglomerating materials within the drum. This granulation method meets the needs of large-scale production while balancing product quality and cost control, making them a key player in industrial production.
The primary advantage of a rotary drum granulator is its wide range of applications. Whether it’s nitrogen, phosphorus, and potassium mixed raw materials in fertilizer production, grain and additive mixtures in the feed industry, or metal ore powder and non-metallic slag in mineral processing, it can reliably process them. Different materials can be processed by simply adjusting parameters such as the rotational speed and inclination angle, eliminating the need for major equipment modifications. This significantly reduces the cost of switching product lines and meets the production needs of a wide variety of products.
Secondly, they offer high productivity and efficiency. The drum design of a rotary drum granulator has a large capacity, allowing a single unit to produce several to tens of tons per hour, far exceeding similar equipment such as disc granulators. Furthermore, the tumbling granulation process within the drum is continuous and stable, eliminating the need for frequent downtime and adjustments. This effectively reduces production interruptions, significantly improving overall production line efficiency and enabling companies to easily meet large-scale mass production needs.
Finally, it offers excellent granulation quality and low energy consumption. Gravity, friction, and centrifugal force combine to form uniform, strong, and resistant granules within the drum, meeting subsequent packaging, transportation, and handling requirements. Furthermore, the equipment consumes relatively little power during operation, saving companies significant electricity costs over long-term use compared to other granulation equipment. Its simple design also reduces maintenance complexity and costs, further improving cost-effectiveness.
With its comprehensive advantages of wide adaptability, high efficiency, excellent quality, and low energy consumption, the rotary drum granulator provides a reliable solution for granulation production in various industries, driving industrial production towards high efficiency, energy conservation, and high quality.
