Description
The frame-type heavy-duty bar screen adopts a high-strength manganese steel frame structure, with wear-resistant alloy steel bars embedded inside as the screen surface. The material screening is achieved through vibration generated by the exciter. Its modular design consists of four core components: the excitation source device, the main body of the screen box, the support spring system and the transmission mechanism. This equipment is suitable for high-load and high-intensity working conditions, such as in the mining, metallurgy, building materials and other industries .
Performance Advantages

2. The top screen surface can be optionally equipped with screening media such as bar screens, needle-shaped screens, perforated screen plates, and polyurethane screen plates. Meet different material handling .
3. The bottom screen surface can be optionally equipped with metal woven screen mesh, rhombic anti-clogging screen mesh, finger screen, string screen and other screening media. Meet the processing requirements of different materials.
4. The Angle, amplitude and vibration intensity of the screen box can all be adjusted. Meet different screening requirements.
5. The whole machine adopts a lightweight structural design. Reduce the overall weight of the machine; Reduce the transportation costs of equipment.
Working Principle
Heavy-duty vibrating screens are typically composed of main components such as screen frames, vibrating motors, eccentric blocks, screen meshes, and bases. Its working principle is that the vibrating motor drives the screen frame to vibrate, thereby enabling the materials on the screen to be sieved and screened during the vibration process.
Specifically, when the vibrating motor is in operation, it generates rotational motion and drives the screen frame to produce high-frequency vibration. The combined effect of centrifugal force and vibration force generated by the eccentric blocks in the screen frame during rotation causes the materials on the screen to be screened in a high-frequency vibration manner. When the particle size of the material is smaller than the aperture of the screen, the material will pass through the screen and fall to the lower layer, while the material larger than the aperture of the screen will remain on the screen, thus achieving the screening and selection of the material.
