Tana introduces new 440 series shredders

Tana, Finland, a leading manufacturer of machines and equipment for the mechanical processing of solid waste, has announced that its 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 the company says is even more versatile, productive and easy to use.

The biggest change externally in the 440DTeco shredder is the new, higher machine frame, which allows for over 200 millimeters (mm) of additional space between the conveyor and the rotor on track models. According to the company, this 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 unshredded materials from falling onto the discharge conveyor.

In addition to the traditional 33-knife rotor, Tana has included the option of 44 knives for added shredding performance. The extended rotor offering includes options for heavy-duty use and for optimizing operating costs. The shredder also comes equipped with an updated labyrinth seal, which has improved the rotor end structure to protect the gearbox from external objects and disturbances.

To further increase productivity and improve the quality of the end product, Tana says it designed the 440DTeco to facilitate a clean and efficient flow of materials.

The cleaning combs are now bolted on instead of welded, enabling for a quicker fix when needed. Different cleaning combs are available for different purposes, such as shorter combs for tougher materials and coarse shredding to ensure the best durability and wear resistance. Longer combs are available for easier materials and fine shredding to ensure the best output quality in terms of homogeneous particle size.

The conveyor system has also been completely redesigned with a new structure that features two separate conveyors: a transfer conveyor underneath the rotor and a discharge conveyor in 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 effortless angle adjustment even during operation. Additionally, the scale system calibrates itself automatically depending on the discharge conveyor angle.

The shredder will feature the new TANA Control System (TCS), a touchscreen display on the side of the machine that can be used to control all of the shredder's function. According to Tana, the new user interface is easy to use and helps the operator find the most efficient settings for each process.
