Inline Vibratory Screen for Continuous Production Lines
Inline vibratory screens are built for continuous production lines, allowing powders and liquids to be screened directly in the pipeline. The compact design saves space while maintaining stable and accurate separation performance. They are widely used in food, pharmaceutical, and chemical processing.
What is an inline vibratory screen?
An inline vibratory screen, also known as a direct discharge vibrating screen, works by having material enter the equipment and then vibrating it in an elliptical motion on the screen surface. This rapid, reciprocating motion, while simultaneously stripping, breaking down, and recombining the material, allows it to pass through the screen quickly. Material that cannot pass through is discharged from the screen’s discharge port along the equipment’s trajectory, completing the screening process.
How Does Inline Vibratory Screening Work?
The vibration source is available in single-motor and dual-motor configurations. A vibrating motor utilizes two sets of eccentric weights (unbalanced weights) located at the upper and lower ends of its shaft to convert the motor’s rotational motion into a superposition of horizontal, vertical, and inclined forces, as well as centrifugal forces. These forces are then transmitted to the screen surface to achieve the screening process. By adjusting the phase angle and weight of the upper and lower eccentric weights, the magnitude of the excitation force and the movement trajectory of the material can be altered.
Single vs Dual Vibration Source
The single-motor design lacks an automatic discharge function; materials that do not pass quickly through the mesh are simply conveyed along the operating path to the discharge outlet, thereby completing the screening process.
The dual-motor design enables three-dimensional movement of the screen surface, enhancing screening efficiency. Thanks to the direct-discharge design at the base, screened material flows out more smoothly. Consequently, for coarse screening applications, it offers higher throughput than single-motor units of the same diameter, demonstrating exceptional performance in raw material screening, in-process screening, pre-packaging screening, and dust removal.

The inline vibrating screen can be easily connected to conveyors, mixers, or filling machines. This makes it the perfect choice for upgrading existing production systems.
Ultrasonic Inline vibratory screen
Ultrasonic straight-line vibrating screen is one of our professional Powder Processing Vibratory Sifters.Similar to a tumbler sieve machine equipped with an ultrasonic device. It is widely utilized across various industries, including pharmaceuticals, chemicals, food processing, and metallurgy. By harnessing the synergistic interplay between high-frequency vibration and ultrasonic waves, the device effectively mitigates factors that cause screen blockage—such as adhesion, friction, particle leveling, and wedging. Ultimately, it resolves complex screening challenges associated with materials exhibiting strong adsorption, easy agglomeration, high static electricity, extreme fineness, high density, or low specific gravity, thereby significantly enhancing the screening performance of ultrafine powders.
