Peterson horizontal grinder still cutting through

The first Peterson horizontal grinder sold into Australia was by Komatsu Forest and it’s still cutting through some of the toughest waste thrown at it. 

With more than 11 years and thousands of hours of operation under its belt, the first Peterson 2710C horizontal grinder sold into Australia is still going strong.

Now on its third assignment, the grinder has found a home in the Riverina region of New South Wales, churning through anything and everything that’s thrown its way at Smallmon Brothers Waste and Recycling. 

And by everything, think tyres, mattresses, green waste, and gravel – among other things. Anything that needs to be processed gets fed through the Peterson, says Chris Smallmon, one of the founders of the waste and recycling company.

Chris and brother Nigel bought the grinder secondhand a few years ago. At the end of 2023 they added to their fleet, purchasing a brand-new Peterson 2710D horizontal grinder from Komatsu Forest.

“We bought a secondhand horizontal grinder through word-of-mouth and have been pretty happy with it,” Chris says.

“When it came time to look for a second machine, we didn’t think of anything else.”

Smallmon Brothers, based in Wagga Wagga, New South Wales, offers a full suite of waste management and recycling services, from collection through to processing.

The company was founded on a commitment to create a cleaner, greener future and is dedicated to responsible waste disposal, recycling, and sustainable practices.

“As long as you keep the maintenance up to them, they keep on performing.”

Understanding the importance of reducing waste volumes and maximising the potential for recycling, the brothers offer onsite crushing, shredding, and grinding services. It’s the grinding service where the Peterson 2710 horizontal grinder comes into its own.

“Through grinding, we transform waste materials into finer particles, facilitating their use in recycling and resource recovery processes,” Chris says.

“Landfill and waste management centre processing, commercial projects, farm clean-ups, bulk scrap or solar farm projects, we do it all.”

Brenton Yon, Komatsu Forest’s Peterson Sales Representative, says the Peterson 2710D is more than just a machine. Its features, adaptability, and efficiency make it an asset for waste management organisations.

The Australian version is fitted with a Caterpillar Tier II C18 570 kW (765 hp) engine and has a large feed opening that allows it to manage a range of materials. Measuring 153 x 81 centimetres, when boosted by Peterson’s high lift feed roll, the feed opening’s maximum lift of 11 centimetres is one of the largest in its class. This is followed by Peterson’s upturn three-stage grinding process, providing better material fracturing and a more consistent product. The quick-change multiple grate system makes it easy to customise grate configurations to produce a variety of finished materials. 

Chris says the size of the end-product depends on the requirement of jobs – local government green waste tends to be smaller material to start with, while a commercial job site will have larger logs and wood to grind. 

“Every project is different, but the Peterson has proven adaptable and adjustable to any job,” Chris says. 

“The touchscreen computer makes for easy adjustments and the new remote lets you control the feed speeds as you’re going.”

Chris says the Peterson has always been user-friendly, but operators are impressed with a new remote control that displays operational functions such as oil temperature, oil pressure, revs and coolant levels. It gives them peace of mind about how the machine is operating and lets them make an informed decision on whether it needs to be slowed down or if maintenance is required.

“Grinders are a funny thing – anyone can turn them on, but it’s knowing what to watch for when they’re working that makes a good operator,” Chris says.

Performance is high on the wish list for a company such as Smallmon Brothers – it can be operating the grinders up to seven-days-a-week, depending on the contracts at any given time.

“At the moment we’re running both grinders in 35-to-40-degree temperatures and it’s not worrying them,” Chris says. “As long as you keep the maintenance up to them, they keep on performing.”

When it comes to maintenance, Komatsu Forest is on call for advice and spare parts. It has a central spare part warehouse and offers an ‘uptime kit’ that includes several critical components to minimise downtime if maintenance is required in a remote location. 

For occasions when Chris has required expert advice or parts, Andrew Watts, Peterson Technical Specialist at Komatsu Forest’s Sydney office, has been on hand. 

When asked if he’d recommend the 2710D, Chris says there’s no need to – they sell themselves.

“The proof is in the product,” he says. “You’ve only got to use one to know they’re a good thing.”
