Shredding the unshreddable: Tutt Bryant

Waste companies are reaping productivity gains from Metso Waste’s M&J 4000M shredder, available through a new partnership with Tutt Bryant Equipment.

Tutt Bryant Equipment has had a long history of serving the waste sector through its iconic BOMAG and Metso brands.

With its various iterations, the machine has for decades helped reduce costs and improve safety through intelligent compaction. While Tutt Bryant is perhaps best-known for its landfill compactors, crushers and screens, the Australian supplier recently bolstered its presence in the waste sector with a new OEM partnership.

With branches in Brisbane, Sydney, Melbourne, Adelaide, Perth and Darwin and a number of independent dealers, Tutt Bryant Equipment is able to support the market effectively.

In September last year, Tutt Bryant became the exclusive distributor for Metso Waste’s mobile shredders, with the first machine sold to Cleanaway. The company offers an array of shredders to the marketplace, from the M&J 4000M to M&J 6000M, available for a variety of throughputs and applications.

Paul Doran, Tutt Bryant Equipment Business Development Manager, explains Metso Waste approached the supplier due to its long history with Metso Minerals in the quarrying sector.

“We’ve been the distributor for crushing and screening equipment for Metso since 2012,” Paul explains.

“Metso Waste realised it was a good fit for us as because of the broad range of products that Tutt Bryant equipment provide in the waste sector, including landfill compactors, crushers, screens, excavators and front end loaders.”

He says Tutt Bryant is seeking to expand its offering to the waste industry by supporting transfer stations with their processing needs.

“This is an opportunity for us to provide a variety of equipment, whether it be crushing concrete, screening waste material or reducing landfill volumes,” he says.

Metso Waste Recycling shredding technology is based on an extremely aggressive knife design and open cutting table, which provides outstanding performance when dealing with mixed and challenging materials.

“A lot of other shredders have a single shaft and rely on the shaft to cut the product, whereas with the Metso design, the knives drive the material into the cutting deck to break it up,” he says.

Paul adds that high-performance pumps maintain high torque levels, in addition to a variety of program settings on the knives allowing both shafts to cut in both directions and  asynchronously.

“They shred materials other machines wouldn’t shred due to a heavy robust engineering design,” Paul says.

He adds the shredder also comprises a detailed fleet management system to monitor the performance of the machine.

“You can get into an amazing level of detail on the pressures, how it’s running and how much fuel it’s using to ensure you’re getting the most out of your investment.”

These key features make M&J PreShred units extremely resistant to wear caused by materials and waste normally considered unshreddable, including solid steel, reinforced concrete and rocks. The machine has sensors that notify the operator of overloading which helps to protect it from damage.

Throughputs can be as high as 100 tonnes per hour depending on the type of input, number of knives specified for the cutting table and loading procedure. The interaction between the rotating knives on these shafts running asynchronously, and in both directions, ensures that the input material is constantly in motion. This prevents bridging and provides maximum shredding capacity.

With the Queensland waste levy underway, management at Cleanaway’s Willawong Transfer Station decided to start looking at shredding materials onsite to reduce volumes and improve separation.

The initial discussions between Cleanaway and Tutt Bryant Equipment were around Cleanaway’s requirement to purchase suitable plant to provide adequate reduction of municipal solid waste. This would enable efficient screening into separate products for further downstream treatment.

Due to great experiences with Metso crushers, the Willawong management team decided to explore the Metso M&J PreShredder range.

Further details and specification options on the M&J 4000M were discussed with Site Operations Manager Chris Thomson. The Tutt Bryant team gained a clear understanding of the impending needs of the site and ongoing volume increases. The large installed base of the units and Chris’ personal experience with Metso Crushers and Screens ensured confidence in the quality and support from Tutt Bryant.

After some benchmarking and considering several different supplier offerings, Cleanaway ordered the M&J4000M and it was delivered to Willawong in July 2019.

“The main reason for selecting the M&J 4000 was that we were confident in it providing the necessary volume reduction, and because of its twin shaft design, we knew it would be very reliable,” Operations Manager Chris Thomson says.

Chris attributes reliability to the Metso build quality and understanding that the production capacity would be there.

After five months of operation, Chris says the machine has performed far better than expected.

“It is user-friendly, even for staff with little exposure to shredders. We got a good feeling about how this relationship was going to go before the machine arrived as Metso Waste and Tutt Bryant senior managers came to site and met with us to discuss the machine and our application,” he says.

“The after-sales support and service from Tutt has been excellent. I can’t fault it.”

The M&J 4000M will be showcased at this year’s Waste 2020 Conference in May at Coffs Harbour.

Mastershred Kreios L Series tackles adhesives

Mastershred, an industry leader in the design and supply of off-the-shelf and customised security destruction and waste reduction solutions, has turned its attention to one of the industry’s biggest challenges.

The company, which specialises in shredders, granulators and crushers, has developed a conveyor-fed twin-shaft shredder. The shredder is designed to meet the demands of the label printing industry and waste operators, covering those who have a requirement to shred bulky items with adhesive coatings for waste reduction or security destruction.

The destruction of these materials has historically proved difficult. This is due to the fact that the adhesive from the label waste matrix has a tendency to block and impede the performance and movement of the shafts and ancillary components.

However, the Mastershred Kreios L Series overcomes these issues with the application of a unique speciality Teflon coating on the shafts and cutters within the chamber and a hydraulic ram to assist the process.

In standard configuration, the Mastershred Kreios L 6360/L 84100 is fed using a variable speed conveyor to deliver the label waste matrix to the hopper. The standard configuration outfeed is fed directly into a Bulka bag which

is suspended on the underside of the shredder frame. Nevertheless, with Mastershred’s ability to customise its range of machines there are various options available to meet operators’ specific in-feed and out-feed requirements, including Teflon-coated screw feed conveyors.

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.
