Introduction to the Linear Vibrating Screen

The linear vibrating screen is a versatile screening device driven by dual vibration motors. When the two vibration motors rotate synchronously in opposite directions, the centrifugal forces generated by their eccentric weights cancel each other out along the direction parallel to the motor shafts, while they add up to form a single, combined force perpendicular to the shafts. As a result, the motion trajectory of the screening machine becomes perfectly linear. Through multiple layers of mesh screens, the machine produces materials of various sizes—some remaining on top of the screens and others passing through—to be discharged separately from their respective outlets. This design makes it ideal for assembly-line operations. Additionally, the axes of the two motors are positioned at an angle relative to the screen surface. Under the combined action of the excitation force and the material’s own gravitational pull, the material is lifted off the screen and propelled forward in a bouncing, linear motion, effectively achieving the purpose of screening and grading. The linear vibrating screen consists of a vibration motor, a screen box, screen meshes, a transmission mechanism, and vibration-damping components. It is particularly well-suited for handling granular materials with relatively high production volumes but not requiring extremely high precision. All parts that come into direct contact with the material are made of 304 stainless steel, while the base structure is crafted from standard carbon steel. This type of vibrating screen boasts several advantages: low energy consumption, high output, a simple yet robust design, ease of maintenance, and a fully enclosed, dust-proof construction that prevents any material spillage. Moreover, it features automatic discharge capabilities, making it especially compatible with continuous production lines. For applications in industries like pharmaceuticals and food processing, the stainless steel linear vibrating screen is available, featuring a fully enclosed design made entirely of 304-grade stainless steel, along with meticulous polishing and sealing treatments to ensure hygiene and compliance with industry standards. On the other hand, the single-layer linear vibrating screen adopts a straightforward, fully enclosed design with a single feed inlet and two discharge outlets. It is optimized for quickly separating materials into just two distinct particle sizes, efficiently removing impurities in the process.
