When landscape supply company Corbet’s Group required a new trommel screen for its commercial compost yard, it enlisted the help of Finlay Screening, Crushing and Recycling Systems.
The history of composting is difficult to track, but reports suggest humans have been engaging in the process for over 10,000 years. According to the Complete Book of Composting, the first ‘written’ account of composting can be traced back to the reign of King Sargon during the Akkadian Dynasty.
While composting is a natural process, the sale of organic matter on a commercial basis requires companies to meet strict standards and regulations. For this reason, Corbet’s Group General Manager Andrew Corbet places significant stock in the screening and separation process.
“An effective trommel screen is crucial to a business like ours given the potential for contamination. You can’t take any chances with the sale of organic material to the public,” Andrew says.
Corbet’s Group, a family-owned logistics and landscape supply business, has been in operation for more than 40 years.
“We produce compost and potting mix with a range of organic materials including topsoil, manure, bark, grass clippings and food waste,” Andrew says.
“Our Sunshine Coast compost yard produces upwards of 5000 yards of compost every month, which we sell to landscapers, bagging companies and large-scale national stores like Bunnings.”
Corbet’s Group produces more than five varieties of compost, meaning flexibility and quick drum change capability were primary concerns for Andrew when making his latest trommel purchase.
“Our products range from potting mix derived from composted bark and minerals, composted green waste for soil conditioning, slash bark for low density media bases and a whole range of other customisable compost products,” Andrew says.
According to Andrew, the Terex Environmental Equipment range, which includes shredders, trommels, recycling screens, waste handlers, grinders and window turners, helps Corbet’s Group effectively manage its processes.
“We’ve had a number of trommels over the years, quite a few different brands actually, but Terex certainly works more effectively and flexibly in my view,” Andrew says.
Finlay, a specialist supplier of screening and processing equipment for the waste recycling industry, is the exclusive dealer of Terex Environmental Equipment.
Andrew has been a customer of the company for many years, having previously purchased crushing and screening equipment from Finlay Sales and Hire Manager Ronnie Bustard in 2015.
“Not long ago, when Andrew was speaking to me about maintenance for an old piece of crushing equipment, he mentioned the company would soon need a new trommel screen for their compost yard,” Ronnie says.
“I suggested the Terex TTS 620 tracked trommel and offered to bring it to the Sunshine Coast for a demonstration. It went really well so Andrew made the purchase. It was all very straightforward.”
Andrew says after acquiring the machine, Ronnie and other members of the Finlay staff trained his operators on how to operate, service and maintain the trommel.
“They went the extra mile by coming up here and making sure my staff knew how to operate the equipment,” Andrew says.
“I’m also sure Ronnie and the team would come to the site if we had any problems, but the trommel runs smoothly every day. We’ve had no issues.”
Andrew says he also purchased multiple aperture barrels, which Ronnie fitted to the new trommel before carrying out tonnage tests.
“The trommel drum has a really quick change out time – it only takes a few minutes before we’re up and running again to screen a new material load,” Andrew says.
“The feeder control system continually adjusts its speed, which means we can process compost at a higher efficiency rate than before.”
Ronnie says the TTS 620 trommel enables application flexibility and it can be utilised for any sort of organics screening.
“All the conveyors are built to a modular design which allows each one to be removed independently and easily configured to various applications. It also means the machine is easy to maintain,” Ronnie says.
“The TTS 620 Terex trommel uses less fuel than standard trommel screens because it has a highly efficient engine. It also has a combined hydraulic drive system enabling advanced material processing control.”
According to Ronnie, the trommel screen’s swing out engine cradle gives operators unrestricted ground level access to all service components, while hinged doors on both sides of the drum offer unobstructed access for maintenance and cleaning.
Andrew says another contributing factor to his decision to enlist Finlay was its spare parts servicing.
“They offer fast and efficient turnaround on aftermarket spare parts – whatever make or model, they have you covered,” Andrew says.
