New Tana 440 Series shredders provide versatility

Published 9/3, 2021 at 13:17

The popular Tana 440 shredders have been further improved in response to feedback from customers and dealers. The first new model of the 440 series is the Tana 440DTeco shredder which is said to be even more versatile, more productive and easier to use.

The versatility, productivity and ease of use of Tana 440 shredders have been taken to a new level following improvements suggested by customers and dealers. The 440 has traditionally been the company’s most popular shredder, being used for processing challenging waste applications, such as mattresses, tyres, plastics, cables and textiles. Versatility was already a major advantage of the Tana shredders, and the new 440DTeco is now said to be even more versatile. The biggest change externally on the new shredder is a higher machine frame, which allows over 200mm more space between the conveyor and the rotor on track models. The new frame structure allows more space for material flow underneath the rotor, helping especially with the pre shredding of bulky materials, such as plastics and mattresses. Similarly, the new hopper design features a raised wall to prevent un-shredded materials from falling onto the discharge conveyor.

In addition to the traditional 33 knife rotor, there is also a new option of 44 knives for added shredding performance. For example, the 44 knife rotor has been found to increase capacity / output in tyre shredding by 25 %. The extended rotor offering also includes options for heavy duty use and for optimising operating costs. In addition, with the updated labyrinth seal the rotor end structure has been improved to protect the gearbox from external objects.


Clean and efficient flow of materials

The flow of materials through the shredder has been improved in many ways in the new 440 series when compared to its predecessor. This further increases productivity and improves the quality of the end product. The cleaning combs are now bolted on instead of welded, enabling a quicker fix when needed, with different cleaning combs being available for different purposes. Shorter combs for tougher materials and coarse shredding to ensure the best durability and wear resistance; longer combs are for easier materials and fine shredding to ensure the best output quality in terms of homogeneous particle size, whereas bolt on cleaning combs also make maintenance easier being easily replaced if damaged.

The conveyor system has been completely redesigned. The new structure features two separate conveyors: a transfer conveyor underneath the rotor and a discharge conveyor at the end of the machine. The speed of both conveyors can be adjusted separately. The frame of the discharge conveyor is now self-supporting enabling easy angle adjustment, even during operation. Also, the scale system calibrates itself automatically depending on the discharge conveyor angle. The optional over band magnet also features many updates, with the magnet being repositioned higher allowing larger metal piles, whereas the space between the magnet conveyor and the discharge conveyor can now be adjusted hydraulically during operation, and the discharge side can be changed.

A new ‘Tana Control System’ (TCS) features a touchscreen display on the side of the shredder that is used to control all of the machine’s functions safely and in one place. The new user interface is extremely easy to use and helps the operator find the most efficient settings for each process. The new and improved TCS with added ‘sensoring’ and updated electrical control enables operation to be more efficient and precise. The operating system can be updated remotely and the ‘TANA ProTrack’ information management system helps optimise the shredder’s utilisation rate and save fuel.


Global services keep the wheels spinning 

The new Tana 440 series combines 15 years of user experience with Tana ‘Shark’ shredders with the latest technical innovations. Tana’s customers and dealers have played a key role in the development of the new shredder series. The 440 shredders are available as track, trailer and electric models. The TANAProTrack information management system, Tana service kits and a global sales and service network help maximise productivity at all times, anywhere in the world.
