Basic introduction of External Rotary Drum Screen
Publish Time: 2022-01-30 Origin: Site
The External Rotary Drum Screen is a unique vibrating device that is powered by either a vibration motor or a regular (explosion-proof) motor. It uses the concept of imbalance to transfer the motor's force onto the screen surface. This causes the materials on the screen to move in a three-dimensional manner. By adjusting the eccentric blocks at the top and bottom, the path of the materials on the screen can be altered to achieve optimal screening results.

The structure principle of External Rotary Drum Screen
The screening of the External Rotary Drum Screen is achieved by the excitation force generated by the eccentric blocks at both ends of the vibrating body. The movement of the upper eccentric block is used to shake the machine to spread the material from the center to the outside on the screen surface; the lower eccentric block makes the material on the surface of the External Rotary Drum Screen produce vertical vibration. The combination of the vibration of the upper and lower eccentric blocks makes the material produce special three-dimensional motion on the screen. The change of the phase angle of the upper and lower eccentric blocks can change the vibration properties. According to the specific gravity of the material, in dry and wet conditions, adjust the phase angle and the seeding ratio of the partial signal block to achieve accurate classification rate and maximum output, and achieve satisfactory screening and filtering effects.

The regular motor positioned on the side of the machine base propels the car with a V-shaped belt. The V-shaped car is connected to the vibrating body using either a driving spring or a driving belt. This method of force transmission ensures that the material on the surface of the External Rotary Drum Screen is evenly spread. The optimal screening effect can be achieved by adjusting the vibration frequency based on the material and machine type. The speed and trajectory radius of the material can also be adjusted to achieve the best resolution and maximum output for different materials. The vibrating body is made using advanced casting technology, resulting in a longer lifespan and improved equipment performance. Additionally, a specialized vibration bearing is used, providing a better vibration effect compared to similar products. The screen configuration of the External Rotary Drum Screen is designed based on the number of screens and customer convenience. Different configurations are available to meet specific requirements. The equipment outlet direction can be customized to suit individual needs.
