1. Drum structure

A reasonable drum length and diameter ratio is the key. A drum with a properly designed length-to-diameter ratio can ensure that the material has enough residence time inside for granulation without causing material blockage or poor flow. The inner wall design of the drum is also very important and should have good wear resistance, such as using special wear-resistant coatings or high-quality metal materials to reduce the wear of the material on the inner wall and extend the service life of the equipment.

2. Feeding and discharging device

The design of the feeding port should ensure that the material enters the drum evenly to avoid uneven granulation caused by uneven feeding. For example, a feeding device with adjustable feeding speed and direction should be used. The discharging port should be able to discharge the finished particles smoothly to prevent the particles from accumulating or breaking at the outlet.

3. Manufacturing process

When manufacturing a qualified Rotary Drum Granulator, the welding parts of the drum should be firm and seamless. High-quality welding can ensure the structural stability of the drum when it rotates at high speed and avoid cracks, which will affect the normal operation of the equipment. Moreover, the processing accuracy of the drum also directly affects the stability of its rotation. The roundness and concentricity of the drum processed with high precision can meet higher standards, reduce vibration and noise, and improve the granulation effect.

4. Performance parameters

A Rotary Drum Granulator with qualified quality should have a reasonable and adjustable speed range to meet the needs of granulating different materials. Moreover, the production capacity of the equipment should also meet the established indicators, and the produced particles should meet the requirements, including the shape, size, compactness, etc. of the particles.

5. Accessory quality

The motor should have sufficient power to drive the drum to operate normally. At the same time, the motor should have high efficiency, low energy consumption, and good heat dissipation performance to ensure long-term stable operation. Transmission parts such as belts and chains should be of reliable quality. The belts should have good flexibility and wear resistance, and the chains should be strong and not easy to break to ensure the high efficiency of power transmission.

In short, comprehensive evaluation from the above multiple aspects can accurately determine whether the quality of the Rotary Drum Granulator is qualified.
