Working principle of rotary drum granulator
The working principle of the drum granulator utilizes the mechanical stirring force of high-speed rotation and the aerodynamic force generated to achieve continuous processing of fine powder through continuous mixing, granulation, spheroidization, and densification in the machine. This comprehensive approach is very effective and can produce spherical particles with a sphericity equal to or greater than 0.7 and a particle size typically between 0.3 and 3 mm. It is worth noting that the granulation rate can reach more than 95%.
The machine comprises five main components:
- Bracket Part: This section supports the entire rotating part of the machine body, enduring substantial forces. To ensure durability, the wheel frame is fabricated using medium carbon steel plates and channel steel. High-quality anti-corrosion and wear-resistant materials are used for the support wheel, enhancing the machine’s lifespan. The frame adopts integrated casting technology, and lifting hooks are positioned at the four corners of the wheel frame for convenient loading, unloading, and transportation.
- Transmission Part: The crucial transmission part governs the entire granulator’s operation. The transmission frame, constructed with high-quality channel steel, hosts a reliable main motor and reducer. The electric motor propels the main shaft through a system involving pulleys, V-belts, and the reducer. A nylon coupling in the working section of the main shaft facilitates engagement and drive transmission.
- Large Gear: This gear, affixed to the machine body, interlocks with the transmission pinion, propelling the machine body in opposite directions. It is crafted from high-tech wear-resistant materials to extend the machine’s service life.
- Rolling Belt: Positioned on both sides of the machine body, the rolling belt provides support for the entire machine structure.
- Body Part: The pivotal component of the granulator, the body part, is constructed from high-quality steel plates. It features a built-in special rubber lining or acid-resistant stainless steel lining to achieve automatic scar removal and tumor removal. This design eliminates the need for a traditional scraper device, fulfilling the intended purpose of the machine.
The drum granulator is suitable for granulating a variety of raw materials, including organic waste, such as livestock and poultry manure, kitchen waste, plant residues, etc.
What are the advantages of rotary drum granulator?
Uniform granulation: The drum granulator rotates the drum so that the raw materials are uniformly stressed and mixed in the drum, thereby producing uniform particles.
Efficient production: This granulator can complete the granulation process in a shorter time, improving production efficiency. The design of the drum allows the material to be more fully compressed and rubbed, helping to form uniform and dense particles.
Easy operation and maintenance: Drum granulators usually have a simple structure and operating interface, making them easy to operate and maintain. This helps reduce management and maintenance costs during production.
Controllable particle size: Users can control the size of the particles produced by adjusting the operating parameters of the drum granulator, such as rotation speed and feed volume, to meet different needs.
Energy saving and environmental protection: Some advanced drum granulators adopt energy-saving and environmentally friendly designs, which reduce energy consumption and reduce the impact on the environment.
High degree of automation: Some drum granulators are equipped with advanced automation control systems, which can realize intelligent monitoring and control of the production process, improving the stability and controllability of production.
