Definition of rotary drum granulator

A rotary drum granulator is a device that converts powdered materials into granular materials through mechanical force. In the field of agriculture, it is mainly used for the production of compound fertilizers, organic fertilizers, biological fertilizers, controlled-release fertilizers and other fertilizers, and is an indispensable key equipment on the fertilizer production line.

Working principle of rotary drum granulator

The main working mode of the rotary drum granulator is wet granulation of pellets. The specific process is as follows:

• By adding a certain amount of water or steam, the crushed material undergoes a thorough chemical reaction after being humidified inside the cylinder.
• Under certain liquid phase conditions, the rotational motion of the cylinder generates squeezing force between material particles, causing them to aggregate into balls.
• The material is added from the feeding end, processed into particles through the special structure inside the cylinder, and finally flows out from the discharge port.

Organic fertilizer granulator

• Wide applicability: Suitable for large-scale production of cold and hot granulation as well as high, medium, and low concentration compound fertilizers.
• High production efficiency: Due to the continuous entry of materials and the continuous rotation of the granulator, large-scale production can be achieved.
• Reasonable design: The machine barrel is lined with special rubber plates or acid resistant stainless steel plates, which realizes automatic scar removal and tumor removal, eliminates the traditional scraper device, and extends the service life of the equipment.
• Flexible process: It can complete the granulation process of compound fertilizer with chemical reactions and heating inside the cylinder, or the cold granulation process of compound fertilizer with a small amount of water supplementation.

• Machines of different models and specifications have different production capacities and applicable ranges, resulting in varying prices.
• High quality materials and advanced manufacturing processes will increase manufacturing costs, thereby affecting selling prices.
• Additional features and configurations, such as automated control systems, will increase the price of the equipment.
• Well known brands and comprehensive after-sales service usually lead to higher prices.
• The market supply and demand relationship is also an important factor in determining prices, and prices may rise when demand exceeds supply.
