TANA modular disc screen offers quick and precise particle size control

The TANA Raven X550T disc screen is a new addition to the TANA recycling machine portfolio. The TANA Raven combines a modern design with enhanced functionality, delivering results in a wide range of waste processing applications. Designed entirely in-house, the new disc screen incorporates several patented smart solutions. 

The disc screen offers modularity and efficiency 

The TANA Raven X550T disc screen separates material into two categories — oversized and undersized — 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 that allow quick adjustments to achieve different particle sizes. For instance, the first quarter of the table can separate fine pieces under 20 mm, while the rest screens medium fractions between 20 to 100 mm, with larger materials classified as oversized. The modular design also allows future modifications and the development of new particle size options. 

The discs are efficiently and precisely manufactured by injection molding, which 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 wear simpler and more affordable. Additionally, the discs weigh up to 75 percent less than steel discs, enhancing efficiency. The unique design of the screen discs is also patent-protected. 

"We wanted to make the Raven disc screen is 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. 

"The smart TANA Control System 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. 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. 

The TanaConnect portal 

A remote monitoring system has been available on all TANA machines for over a decade. Now, it has been further developed into the TanaConnect portal, offering new features and a user-friendly interface. This fleet management system collects, analyzes, and presents machine data to streamline operations, boost team motivation, and enhance productivity. TanaConnect is also included in the TANA Raven disc screen. 

A live machine overview provides detailed insights into machine condition and performance. Information from the TanaConnect portal can also be integrated with other systems, such as maintenance management, production management, or ERP systems through the TanaConnect API. 

The digital portal enables real-time fleet management, keeping users up to date with key information, including: 

• Machine health information 
• Production reports 
• Machine alarms 
• Machine events 
• Machine service information 
• TANA documents
