Linear vibrating screens
Sieving that is gentle on the product and energy-efficient
Linear vibrating screens work with a flywheel drive that sets the screening trough into a purely horizontal screening motion.
The material to be screened remains on the screen mesh throughout the entire screening process. For this reason, linear vibrating screens are the ideal solution for fragile products – from fragile tea, to nut splinters, to catalysts.
The flywheel drive consists of a large flywheel with unbalanced weights. The drive is connected to the screening trough via push rods. Thus, when the drive is activated, the trough is set into a horizontal swinging motion, which is further supported by special springs on the trough.
Flywheel drives have a low energy requirement. The maximum power of the drive is only needed when starting the machine. Part of the oscillating movement is already maintained by the springs and the unbalance disc of the drive.
Optimum adaptation to the product-specific properties is achieved by adjusting the stroke and the screen inclination.

Core components of
Linear vibrating screens
Flywheel drive
The flywheel drive is connected to the screening trough via push rods.
This sets the screen housing into a gentle, horizontal oscillating movement.
Linear vibrating screens are therefore considered to be particularly energy-efficient and, above all, low-noise.
Frame and sieve trough
The housing is spring-mounted so that it can swing freely, decoupled from the frame.
The product to be sieved is fed into the sieve trough via the inlet, where it falls onto the sieve inserter.
Due to the almost horizontal oscillating movement, the material to be screened is always in full contact with the screen mesh. This enables particularly gentle and, above all, sharp screening.
Adjustment of inclination
The angle of inclination of the sieve housing in the frame is adjustable.
With a steeper angle, the material moves faster over the screen inserter. With a flatter angle, the dwell time on the screen feeder is extended.
This means that the sieve can always be optimally adapted to the flow behaviour of the product.

Project highlights
Linear vibrating screens
Problems with agglomerates in the product can be solved well!
You know the situation: when working with bulk material, agglomerates and lumps are not uncommon. We have compiled a list of screening and crushing machines that can help in such cases. Always with the product in mind, because that’s what matters.
Separation of coarse and fine grain before tea filling
Various types of tea are to be freed from small dust particles and breakage as well as from larger foreign bodies before packaging – and this as gently as possible. Find out how we solved the task with the JEL Freischwinger linear stroke screening machine in this project example.
Coarse and fine grain separation in the production of ceramic media
Polymethylmethacrylat (PMMA) wird als Rohstoff für die Herstellung verschiedenster Endprodukte genutzt. Im Dental- und Sanitärkeramiksegment sind dabei konsistente Qualitäten in engen Spezifikationsgrenzen ein Muss. Eine Aufgabe für die Schwingsiebmaschine JEL Freischwinger.
