Finger Cascade Screen TopSpin
The Finger Cascade Screen TopSpin has been specially developed for the pre-classification of difficult-to-screen products in recycling plants.
It is used wherever conventional screening systems reach their limits – for example, with fibrous, elongated, or contaminated mixed fractions.
The cascade steps ensure particularly effective product circulation, while the screen surface guarantees high throughput and clog-free screening. While fines are reliably screened out, elongated pieces are specifically discharged via the screen overflow.
The system is based on a circular vibratory screen with shaft drive, achieving above-average acceleration values – ideal for materials such as ASR, shredder residues, RDF, MHW, or waste wood. In combination with optional features such as vibration monitoring, covers, or maintenance platforms, the TopSpin cascade screen offers a reliable and low-maintenance solution for demanding applications.
FUNCTION
The circular vibratory motion is generated by a shaft drive with unbalance system, ensuring uniform material distribution across the screen deck. The material is conveyed over several stages – the so‑called cascades. At each step, the conveying material is deliberately overturned, loosening the product and distributing it evenly over the screen surface.
While fine and small-particle material passes through the screen surface, elongated pieces, contaminants, and oversize particles are discharged over the overflow. This effect makes the cascade screen the ideal solution for difficult-to-screen, fibrous, or inhomogeneous mixed materials, where conventional screening machines tend to clog or lose separation efficiency.
Thanks to the design of the screen surface and the high acceleration values, the screen remains almost clog-free, even in demanding applications. The machines can be adapted to specific requirements in length, width, inclination, and design – ensuring a stable, low-maintenance, and efficient screening process.

Fields of Application
Fields of Application
The JOEST cascade screen is the ideal solution for the pre-classification of difficult-to-screen, inhomogeneous, or elongated materials, which tend to cause clogging or insufficient separation efficiency in conventional screening plants. Thanks to its special design featuring a cascade deck, circular motion, and robust construction, it is particularly well suited for demanding recycling processes with varying material fractions.
Shredder residues (ASR), refuse-derived fuels (EBS, RDF), mixed municipal waste, household waste (MHW), bulky waste, plastics, used tires
mixed scrap, light metal fractions, contaminated construction waste
waste wood, rootstocks, mixed wood with foreign materials
Equipment Options
For optimal adaptation to material, process, and plant environment, the cascade screen offers numerous equipment options – flexibly configurable and proven in practice.
Adjustable Cascade Deck Geometry
The number, shape, and inclination of the cascade steps are designed according to process requirements – for maximum product circulation and reliable separation results.
Single- or Multi-Deck Design
The cascade screen is available as a single- or multi-deck system, depending on the desired separation accuracy, feed material, and available space on site.
Protective Covers
Depending on the environment and material properties, the machine can be equipped with a cover – improving safety and cleanliness.
Integrated Maintenance and Inspection Openings
Generously sized inspection openings facilitate cleaning, inspection, and maintenance – reducing downtime and enabling easy handling.
Walk-On Platform for Maintenance and Operation
A sturdy maintenance platform can optionally be supplied – ensuring safe access to the machine for inspection, cleaning, or adjustment work.
Vibration and Oscillation Monitoring Possible
Sensors can be integrated for process control to monitor machine condition and oscillation behavior in real time and visualize the data.
ATEX-Compliant Version Available on Request
For use in hazardous areas, a certified ATEX version with standardized components is available.
Special Designs Available
Depending on process requirements, the cascade screen can be supplied in stainless steel or with special coatings – e.g. for aggressive media.
Advantages
The cascade screen has been specially developed for the separation of difficult-to-screen materials. Thanks to its circular vibratory motion, open deck geometry, and robust design, it offers an exceptionally clog-free, high-performance, and durable solution – ideal for use in recycling processes with varying material streams.
