Basic introduction of External Rotary Drum Screen

The External Rotary Drum Screen is a special vibrator driven by a vibration motor or an ordinary (explosion-proof) motor as the excitation source. According to the principle of unbalance, the force of the motor is transmitted to the screen surface. And decompose and synthesize, make the materials on the External Rotary Drum Screen. The surface makes a three-dimensional movement. By adjusting the eccentric blocks at the upper and lower ends, the movement trajectory of the material on the screen surface is changed, to achieve the best screening effect.

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.

Structural features of External Rotary Drum Screen

The ordinary motor standing on the side of the machine base drives the V-shaped car through the movement of the V-shaped belt. The V-shaped car and the vibrating body are connected by a driving spring or a driving belt. This kind of force transmission effect is uniform, which can make the material in the External Rotary Drum Screen is evenly dispersed on the surface; according to different materials and different types of machines, the required vibration frequency needs to be adjusted to achieve the best screening effect. The movement speed of the material and the radius of the movement trajectory of the material are adjustable to achieve the best resolution and maximum output of different materials; the vibrating body adopts professional casting technology to make the vibrating body longer service life, thereby improving the performance of the equipment, and the vibrating body adopts a dedicated vibration bearing, and make the vibration effect better than similar products. The screen setting of the External Rotary Drum Screen is based on the number of screens and the convenience of the customer. Different devices are designed to meet the needs; the direction of the equipment outlet can be changed along the circumference, fully enclosed, and the level can be free according to requirements Combination, up to four floors.
