The TDS 825 slow-speed shredder

Terex Ecotec has launched a range of TDS 825 robust twin shaft, slow-speed shredders, ideal for large scale operations.

The high capacity machine is suitable for all material types including household waste, bulky waste, commercial waste, green waste, waste wood, tree stumps and roots.

Customisable shredding programs allow operators to configure the machine to their specific requirements to maximise production.

The hydrostatic drive offers protection against contamination and allows for bidirectional shredding, while independent gear boxes enable each shaft to run separately, helping reduce wrappage and improve shredding.

Should a blockage occur the shafts can be controlled via the radio remote control, allowing material to be repositioned before attempting to shred again.

The double shaft shredder has 2.5 long shafts made from solid steel, with a fully welded tooth configuration giving an extremely high production rate with excellent size reduction.

Located in the centre of the chamber, directly below the shredding shafts is the replaceable breaker bar, which controls the end product size by retaining material in the chamber to aid reduction and protects the transfer belt from damage caused by large pieces of contaminants.

A number of breaker bar options are available depending on the level of reduction required, these are easily replaceable due to News Release the side door chamber access.

Powered by a 770HP Scania V8 DC16 engine, the machine has been designed to provide operators with unrivalled levels of service access.

The high volume, tipping hopper increases the feed area providing optimum material feed and can be activated using the control panel or via the remote control. Tipping cycle times can be configured to suit the application.

Hydraulic folding hopper extensions allows for increased capacity, preventing the infeed material from falling out especially in bulky applications.

The overband magnet providing magnetic separation is both height and angle adjustable hydraulically, and lifts up and away from the product conveyor when not in use. All conveyors are built to a modular design allowing each one to be removed independently for ease of maintenance.

A separate transfer conveyor with a high specification belt ensures material is effectively removed from below the shredding chamber. The product conveyor raises hydraulically and folds into maintenance mode to allow removal of the transfer conveyor.

The TDS 825 is manoeuvred via a robust tracked undercarriage making it a great solution for difficult terrain.

The new TDS 825 Slow Speed Shredder is now available in Australia from Finlay Screening & Crushing Systems.

Mobile multivitamin: Finlay

Craig Turner, Bio Gro Project Manager, talks to Waste Management Review about improving soil health through high-energy screening.

The viability of Australia’s productive land is being challenged by extreme weather conditions, as droughts and floods alter soil compositions and reduce nutrient levels.

Sustainability Victoria modelling suggests that as a result, the country’s agricultural and horticultural sectors will feel higher rates of climate change than other sectors.

Van Schaik’s Bio Gro, a family-owned company based in Mount Gambier, South Australia that supplies growing media, mulches and composts, are working to limit these impacts by stimulating soil health and reducing organic methane emissions.

Craig Turner, Bio Gro Project Manager, says the company works in partnership with various councils and private organisations to achieve optimum organic resource recovery. He says that currently, it processes in excess of 750,000 cubic metres of organic material per annum.

“The organic material is processed into a range of specialist growing and mulching mediums, soil amendments and biological growth stimulants, perfectly tailored for the urban amenity, intensive and extensive agriculture and viticulture markets,” Craig says.

“To effectively process the organic material, which is inconsistent and varied by nature, we require high-intensity screening equipment, which is why we work with Finlay Screening, Crushing and Recycling Systems.”

Bio Gro and Finlay’s relationship began in the early 2000s, when Finlay supplied the company with a Terex 693 Double Deck screener for mulch processing.

“Finlay offers a quality product with great service and advice, is always fast to respond to any issues we have and supplies a good spare parts service with 24-hour support,” Craig says.

“When we required a new screen to address high moisture level and increase productions times, Finlay was the obvious choice.”

After considerable consultation and on-site testing, Bio Gro purchased a Spaleck Flip Flow from Finlay in 2017.

“We needed a screen that could produce at the required volume without operators having to regularly clean screen decks, which causes downtime and poses a significant safety risk to our staff,” Craig explains.

“Additionally, we wanted a mobile screen that was versatile enough to process the wide range of organic material we receive.”

Craig says Bio Gro uses the Flip Flow to screen and separate compost bark, organic compost and recycled timber, at up to 100 cubic metres an hour.

Spaleck Flip Flow screens are designed to screen damp and wet materials of inhomogeneous origin, with separation cuts of 1.2 to approximately 50 millimetres.

According to Craig, the machine’s base frame is agitated by a shaft and unbalanced motor drive, with vibrations passed to the frame through thrust rubbers to produce reliable and high-energy screening.

A key component of the mobile system is the Spaleck 3D Combi Flip-Flow screen, which Craig says screens and loosens material on a top deck with optimal turning.

“The screen deck is mounted above the Flip-Flow deck to form a cascade, with 3D screen segments to reduce loads for the flip-flow screen mat,” he says.

“This increases the mat service life and guarantees optimum screening results. Plus, the screen mats are secured without screws, meaning there are no sharp edges or safety hazards.”

Craig adds that the 3D screening segments guarantee correct particle size, with no long pieces or extraneous material passed to the tension shaft screen on the lower deck.

“The Flip Flow has far exceeded our expectations and helped Bio Gro reduce safety risks, improve output performance and meet all our product quality requirements,” Craig says.

“The screen hasn’t suffered any blockages or downtime to date, which means we can consistently produce nutrient rich mulch and soil amendments to feed our land and protect the environment.”

Finlay: woodchips to energy

Veolia’s recent moves in the waste-to-energy market has seen them team up with specialist equipment supplier Finlay.

Populations are growing and, as a result, so too is waste generation. Conversely, landfill capacity is declining as urban areas become increasingly dense.

While the waste hierarchy privileges avoidance, reuse and recycling, interest in waste-to-energy as a solution for material that falls through the cracks is growing. Capturing this potential was the driving force behind Veolia’s decision to open a new facility in Horsley Park, New South Wales.

According to site manager Stephen Bernhart, the new resource recovery facility handles wood waste material, which it then processes into a wood chip product.

“After running multiple equipment trials in 2018, we have recently kicked into operation,” Stephen says.

He adds that the wood chip product will be provided to a customer where it will be used as a substitute for coal within a cement kiln.

Veolia’s facility processes a significant amount of wood waste, such as pallets, offcuts and plywood which need to be shredded, and has the capacity to receive 430,000 tonnes of general solid non-putrescible waste per year.

“We have detailed specifications we need to meet to supply our waste-to-energy customer, and a big part of that is ensuring we achieved a material size sub 50 millimetres,” he says.

“It’s quite a challenging task because it’s such a small grade, so we decided to invite multiple suppliers out to the site to run tests and demonstrate their equipment.”

Stephen says Finlay Screening, Crushing and Recycling Systems, a supplier of screening and processing equipment for the waste and recycling industry, stood out during the trials.

“Finlay were heads and shoulders above the rest in demonstrating not just what their equipment could achieve, but how it could achieve it consistently,” he explains.   

Finlay initially trialed a medium speed shredder, however, the resulting material didn’t quite meet specifications. Three weeks later they were back, with a Terex Finlay 693+ Super Track Screening Plant that, according to Stephen, worked extremely well.

“During the second trial there was a large lump of steel which had passed through the primary shredder into the secondary shredder,” Stephen says.

“The TDSV20 shredder shut down as intended, and Finlay representatives opened it up to remove the steel. The machine was back up and running in approximately three minutes – I was very impressed with how the equipment handled it.”

According to Stephen, Finlay also demonstrated how the shredding equipment could maintain the required tonnage throughput in spite of the small material specifications.

In addition to the screening plant, Stephen purchased a Terex Finlay TDS 820 Slow Speed Shredder and a Terex Finlay TDS V20 Mid Speed Shredder and Finlay 5032HD wheeled conveyor.

Built to process bulky, solid waste, the TDS 820 has a two-metre shaft manufactured with a fully welded tooth configuration. Stephen explains that the length allows for significant throughput and size reduction of material.

“The machine’s independent gearboxes enable each shaft to be run separately, which reduces material wrappage and facilitates viable shredding,” he adds.

The Terex Mid Speed Shredder has a twin-shaft, allowing it to perform both primary and secondary shredding. The TDS V20 also has the ability to self-protect against uncrushable material like steel, making it well suited to shredding waste wood materials.

“We have had no trouble meeting specifications after procuring the equipment, all three machines have been running very well.”

According to Stephen, there has been very little down time at the Horsley Park facility.

“There were one or two minor teething issues initially, but Finlay were able to handle them quickly and without fuss,” he says.

Finlay representatives also assisted on-site equipment training when the facility was commissioned.

“They are very forthcoming with their information and we were able to get local contractors trained up on how to run and maintain the shredders and screening plant as well,” he says.

“We are at a really exciting stage in our capability with an eye for expansion, so it’s crucial to have equipment that’s both reliable and efficient.”
