As an important component of granulation equipment, the rotary drum granulator's equipment principle has continuously evolved over a long period of development, accompanied by a series of technological innovations to adapt to the growing industrial production demand.

The traditional working principle of a rotary drum granulator is based on the rotation of the drum, which causes the material to circulate in the drum under the action of centrifugal force, friction force, and gravity, and achieves particle formation and growth by spraying adhesive. With the advancement of technology, the rotary drum granulator has undergone technological innovation in multiple aspects.

In terms of the feeding system, advanced quantitative feeding technology has been introduced. Through high-precision sensors and intelligent control systems, the feeding speed and quantity of materials can be accurately controlled to ensure uniform distribution of materials inside the drum. This not only improves the consistency and stability of the particles, but also avoids granulation quality problems caused by uneven feeding.

The spraying system has also been significantly improved. The new spraying device adopts a nozzle with better atomization effect, which can spray the adhesive more evenly on the material. Meanwhile, through an automated control system, the amount of adhesive sprayed can be adjusted in real-time based on the flow rate of materials and the speed of the drum, ensuring the optimal bonding effect.

The design of the drum has also been innovated. Some rotary drum granulators use adjustable internal structure rotary drums, such as adjusting the angle and quantity of the plate according to material characteristics and granulation requirements. This can more flexibly control the movement trajectory and residence time of materials in the drum, further optimizing the granulation process.

In addition, the application of intelligent control technology is a major innovative highlight of rotary drum granulators. Operators can monitor the real-time operation status of equipment, including parameters such as drum speed, temperature, and pressure, through a remote monitoring system. Once an abnormal situation occurs, the system can automatically sound an alarm and take corresponding measures to ensure the safe and stable operation of the equipment. At the same time, the intelligent control system can automatically adjust the operation of the equipment according to preset parameters, improving production efficiency and product quality.

In terms of energy utilization, the rotary drum granulator is also constantly innovating. Some new equipment adopts energy-saving motors and optimized transmission systems, reducing the energy consumption of the equipment and meeting the requirements of modern industry for energy conservation and environmental protection.

The rotary drum granulator has made significant progress in feeding system, spraying system, rotary drum design, intelligent control, and energy utilization through continuous technological innovation based on equipment principles, bringing higher efficiency, better product quality, and lower energy consumption to industrial granulation production, and promoting the continuous development of granulation technology.
