TANA Raven X550T disc screen: agile screening combined with versatility and intelligence
The TANA Raven X550T disc screen is a highly requested addition to the TANA recycling machine portfolio. The TANA Raven combines robust design with intelligent functionality, delivering exceptional results in a wide range of waste processing applications. Designed entirely in-house, the new disc screen incorporates several patented smart solutions.
"We wanted to make the Raven disc screen versatile, cost-effective, and user-friendly. A key feature of our disc screen is its modular screening table, which allows for quick adjustments to the desired particle size. This also facilitates service," says Eetu Tuovinen, Product Manager, Recycling.
Modularity & efficiency
The TANA Raven X550T disc screen, by default, separates material into two fractions - oversize and undersize - but can be equipped with an optional three-fraction screening package for finer separation. This versatility is enabled by Tana’s patented modular screening table, which consists of four interchangeable modules, allowing quick adjustments to achieve different particle sizes. For instance, the first quarter of the table can separate fines under 20 mm, while the rest screens medium fractions between 20–100 mm, with larger materials classified as oversized. The modular design also allows future modifications, and the development of new particle size options based on customer needs.
The discs are efficiently and precisely manufactured by injection molding, this offers a simple, quiet, durable and cost-efficient design. The smart anti-wrapping design also eliminates the need for separate anti-wrapping systems, making spares and wears simpler and more affordable for our customers. Additionally, the discs weigh up to 75% less than steel discs, enhancing efficiency. The unique design of the screen discs is also patent protected.
"The smart TANA Control System (TCS) detects jams and can reverse the machine when needed. The system also allows users to store different programs for processing various materials," Tuovinen explains.
The TANA shredder and disc screen form an ideal pair, as they can process the same waste types at the same speed. Like its namesake in the animal kingdom, the TANA Raven is highly adaptable and intelligent. The disc screen efficiently handles various types of waste with high capacity, particularly MSW, C&D, and waste wood. The disc screen also features a large hopper, with easy feeding with a wheel loader or a material handler, which allows the screen to be used as a standalone machine. First, we will launch the Stage V diesel engine version which also offers an optional electric screening feature.
