Pre-separators are preferably used before the first crushing stage in quarries, ore mines and slag processing plants. The step-shaped screening surface ensures good re-sifting of the material to be screened.
For feed material with stalky and spiky pieces that tend to jam, we recommend a step grate with gaps that widen in the transport direction for optimum results. Two-deck solutions are also possible and complement the grading process.
We build our eccentric vibratory screening machines for you with nominal screen widths of up to 2100 mm and screen lengths of up to 4000 mm.
For efficient pre-screening with perforated plates or step gratings.
In contrast to free-swinging circular vibrating screens, eccentric vibrating screens are rigidly mounted. This has the positive consequence that the circular motion diameter is permanently maintained and is not reduced by too much feed material. Feed fluctuations or strong impulses caused by individual pieces of rock are easily accepted by our eccentric vibrating screens – they don’t care. The displacement by rubber buffers on a frame, which in turn is insulated from the steel structure, ensures reduced vibration transmission to the steel structure.
By using components that are also used in other screening machines, our eccentric vibratory screening machines guarantee long-lasting and reliable pre-separation.
Screening machines for a wide range of applications have been part of our production program for many years.
Even for seemingly unsolvable screening problems, you should contact us. A well-trained team of engineers and more than 100 years of industry experience are at your disposal.
Here you will find an overview of our extensive range of screening machine accessories, e.g. atomization, wear protection, drive consoles, air suspension, counter-swing frame, dust protection, double imbalance gearbox, hybrid suspension or special screen linings.
The elliptical vibrating screen combines the advantages of linear and circular vibrating screens with space-saving horizontal installation and high material throughput.
A SIEBTECHNIK circular motion screening machine is the classic solution for process engineering tasks in screen classification.
