In the production chains of industries such as fertilizers, building materials, and chemicals, the rotary drum granulator is an indispensable key piece of equipment. Its unique working principle transforms loose powder into uniform granules, laying the foundation for subsequent processing and applications. This equipment, with its high efficiency and stable performance, has become a powerful assistant in modern large-scale industrial production.
The core working area of the rotary drum granulator is a tilted rotating cylinder. When material enters the cylinder, it rolls spirally along the cylinder wall under the combined action of centrifugal force, gravity, and friction generated by the cylinder's rotation. Simultaneously, a spray system evenly sprays a binder, causing the powder material to gradually agglomerate into nuclei. Through continuous collision and rolling, the material grows larger, ultimately forming granules with uniform size and suitable strength. Its tilt angle and rotation speed can be precisely adjusted to ensure controllable granulation process, meeting the particle size requirements of different industries.
In the agricultural field, the rotary drum granulator is the core equipment for compound fertilizer production. It can mix and granulate basic fertilizer powders such as nitrogen, phosphorus, and potassium with additives to produce granular fertilizers with good slow-release properties and balanced nutrients, improving fertilizer utilization and reducing environmental pollution. In the building materials industry, it can process cement, gypsum, and other powders into granular raw materials, optimizing material flowability and improving the quality stability of subsequent molded products. Furthermore, in the chemical and mining industries, rotary drum granulators are widely used in waste recycling and material modification processes.
Modern rotary drum granulators are constantly being upgraded, employing wear-resistant liners to extend their service life, equipped with intelligent control systems for precise parameter control, and featuring sealed designs to reduce dust pollution, balancing high-efficiency production with environmental protection requirements. Their simple structure, convenient operation, and low maintenance costs make them popular among small and medium-sized enterprises, becoming an important piece of equipment for promoting the intensive and green development of industrial production.
From granular fertilizers in farmland to new materials in construction, rotary drum granulators, working silently, connect powder raw materials with end products, playing an irreplaceable role in the industrial production value chain and providing solid support for the high-quality development of various industries.
