Astec Industries’ Peterson Horizontal Grinders provide grinding solutions for organics recycling and forestry.
The Peterson brand was founded in 1981 and has been an integral member of Astec Industries since 2007.
Peterson offers a full line of horizontal grinders from 455–1200 horsepower (339–894 kW). They come in both diesel and electric applications to suit any grinding needs. Peterson D-series grinders offer industry-leading features and innovations which allow customers to produce the highest quality product at the lowest cost per ton.
The Australian Peterson distributor, Komatsu Forest, is located at Newington in Sydney. It has branches and agents throughout the Australian forest regions and has been the Peterson dealer since early 2011.
Komatsu Forest has been successful in selling a range of Peterson Horizontal grinders in Australia – the most popular model being the 2710D – with more than 20 units currently operating throughout Australia. The grinder is designed for operations requiring mobility, high production, and frequent moves between jobs.
Powerful Peterson
The 2710D is powerful. The Australian version is fitted with a Caterpillar Tier II C18 570 kW (765 hp). It has a large feed opening allows it to manage a wide range of materials. Measuring 153 x 81 cm, when boosted by Peterson’s high lift feed roll, the feed opening’s maximum lift of 11 cm 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.
Peterson Grinders feature upturning rotors that are configured to produce lighter mulches with fewer fines. The upturning rotors perform more of the reduction process through shearing and cleavage fractures in the wood, making them more productive because less energy is required.
Peterson’s patented Impact Release System’s air bags provide uniform grinding and protection from contaminated feedstock.
In addition, there’s a second line of defence of urethane cushions and shear pins that help protect the mill from catastrophic damage in the event of a severe impact from contaminants in the feed stock.
The Peterson 2710D features can also benefit the bottom line over a 12 month period. It includes a reduction in downtime, fuel consumption, colorant costs, and higher mulch yields.
