When it comes to processing difficult and bulky materials, having a shredder that can adapt to the job is critical. The Terex Ecotec TDS820 slow-speed shredder is designed around that principle, combining high power, independent shaft control and customisable shredding programs to give operators greater control over how material is processed.
At the heart of the TDS820 is a 497HP engine delivering 100,000 Nm of torque on each shaft. It is a true pre-shredder, designed for applications where high forces are required, and its twin-shaft configuration provides the flexibility needed to tackle a range of materials. Each shaft has an independent drive, allowing operators to control shaft speed, direction and the time spent in each configuration.
This level of control is useful when material characteristics change. The TDS820 has adjustable shredding programs that can be changed while the machine is operating. This allows operators to configure the shredder to suit different materials. These programs are designed to reduce material wrapping and maximise production, helping operators get more from the machine as conditions change.
The independently driven shafts are supported by independent gearboxes, allowing each shaft to run separately. Combined with the ability to operate the shafts in different directions, this provides greater flexibility during shredding. The hydrostatic drive also provides increased protection against contamination while allowing bi-directional shredding.
The two-metre-long shafts feature a welded tooth configuration, providing the machine with the ability to generate high throughput and material reduction. For operators working with challenging feedstocks, that combination of torque, shaft control and tooth configuration provides the forces needed to get material moving through the shredder.
Feeding the machine is also designed around demanding applications. The tipping hopper increases the feed area and allows choke feeding, while hydraulic folding hopper extensions provide additional capacity when dealing with large and bulky materials. Together, these features make the machine well suited to applications where the feedstock does not always arrive in neat, consistent sizes.
The TDS820 is built for a range of users across the waste and resource recovery sector. Customers include councils, composters, contractors, transfer stations, landfills and skip bin companies, with applications ranging from green waste and mattresses through to tyres, timber, construction and demolition material, commercial and industrial waste, and large and bulky items.
For operators, the machine’s features extend beyond the shredding chamber. A remote control provides operational controls, while a reversible fan adds flexibility during operation. Automatic lubrication keeps the shafts greased, and hydraulic raise and lower functionality for the over-band magnet adds convenience when configuring the machine.
Material discharge has also been considered in the machine’s design. The transfer conveyor and extended product conveyor are separated, allowing operators to vary stockpile height while also making belt changes easier. A chamber camera provides visibility inside the shredding chamber, helping make the process of clearing blockages more straightforward.
Ease of operation is another important consideration. The TDS820 features an easy-to-use operating system, while its tracked undercarriage allows the machine to be manoeuvred across difficult terrain. That mobility means operators can position the shredder where it is needed, rather than being limited to straightforward working conditions.
Ultimately, the appeal of the TDS820 comes down to control and adaptability. Rather than relying on a single shredding configuration, operators can adjust the machine to suit the material in front of them.
Local agent, Finlay also provides industry-renowned back-up covering service, technical information, process expertise and spares, giving operators support beyond the machine itself. For businesses processing difficult, bulky or variable materials, the Terex Ecotec TDS820 offers the combination of power, flexibility and control needed to keep challenging shredding applications moving.
