Screening machines: Screening technology for numerous tasks
Our solution: reliable and robust screening machines to meet your requirements
S&F screening machines are in use worldwide for numerous different process engineering tasks. Our oscillating screens and gyratory screens, vibrating screens and star screens provide the ideal screening technology for your individual task. S&F screening plants offer straightforward handling, reliability and low maintenance. Thanks to our specialised service personnel and seamless spare parts delivery from stock, screening machines by S&F are designed to do one thing above all else: withstand the test of time.
Screening machines for numerous processing tasks
Screening is a widely used mechanical classification method and separates the feed material into different size classes (fractions). S&F screening technology provides powerful and clean screening and separation of different bulk materials such as wood chips, sawdust, wood pellets and alternative fuels.
Screening machines are used for the following applications and tasks:
- Screening and separating
- Classification and sorting
- Protective screening
- Ultra-fine, fine, medium and coarse-grain screening
- Over-length and oversize material screening
- Check screening
There are many reasons to use our screening technology: It guarantees a uniform, homogeneous raw material that is easier to process thanks to its defined grain size. It can also help boost sales revenues. The removal of unwanted materials increases the fail-safe performance of downstream machines and plant components and delivers many other process advantages.
See below for an overview of our separation and screening technology.
Oscillating screen type ASM
S&F oscillating screens or gyratory screens are used in the wood processing industry (sawmills, pelletising plants) as well as in numerous other industries (recycling and waste disposal, environmental technology). They are suitable for separating lighter wet and dry recyclables and raw materials (wood chips, wood shavings, wood pellets, waste wood).
The horizontal circular movement of the sieve box mounted at an angle conserves the material but guarantees high separation precision. The advantage of the oscillating screen is that long and fibrous particles slide diagonally to tangentially over the screening surface. In contrast to riddles, this does not create any trapped and clogged material.

Vibrating screen type AVS
S&F vibrating screens can be found in a variety of sectors such as the recycling industry (alternative fuels) and other areas (construction materials industry).
The linear vibratory movement guarantees synchronous running of the machine and uniform screening of the bulk material. The pre-set vibration amplitude of the screening machine controls and optimises the screening result.
The type AVS screening machine is robust, reliable and suitable for the classification of granular bulk materials (quartz sand, granulate).

Star screen type AVS / disc screen type ASC
Star screens are used primarily in the wood processing industry and in the recycling sector.
Star screens are suitable for screening damp, fibrous raw materials such as bark or green clippings. Disc screens are used for screening hot materials or for rough pre-screening.
S&F star and disc screens consist of multiple shafts aligned parallel and at the same distance to each other. They are fitted with side-by-side rotating star or disc type wheels. Their robust construction and high throughput rates with low space requirements make them extremely efficient in use.
