Peterson's 6700B Horizontal Recycler: The Profitable Future Of Grinding
Eugene, OR — Designed for the biggest jobs, the Peterson model 6700B Horizontal Recycler earned rave reviews when it was unveiled to recycling professionals at CONEXPO/CONAGG in Las Vegas last month. The 6700B is the newest model in the company's established line of heavy-duty grinders that uniquely converts raw materials into higher value end products.
Powered by a 1000-horsepower Caterpillar 3412E diesel engine, the 6700B is designed for size reduction of large quantities of mixed landfill, construction and wood materials. For example, the feed opening of 50 x 66 inches allows the 6700B to process massive stumps that used to be reserved for tub grinders.
"What our engineers and designers have done is develop a heavy-duty horizontal recycler that combines rugged, grinding power with many innovative features. Operators can adjust settings to maximize production and specialized, end-products. This is the future of grinding. Now more than ever it's essential to seek out all possible profit centers and embrace operational efficiencies that impact the bottom line," says Peterson President Neil Peterson. "With the 6700B, new opportunities for high-speed grinding of MSW and certain types of C&D finally make sense."
Innovative new features for the 6700B include:
- Adaptive Control System. This system controls all components of the feed system to optimize output. This third-generation system monitors the grinding load and varies the speed of the feed system to keep the engine working at the top of its power curve. It automatically accelerates the feed system when the engine load is light, slows when the load is high, and reverses when the engine speed hits a pre-set level. It even monitors the engine temperature and varies the speed of the cooling fans to optimize cooling while minimizing power usage and reducing fuel consumption.
- Three-stage grinding. This unique process consists of an up turning rotor and large grate area that enables the 6700B to produce materials to exact specifications. The Peterson quick-change multiple grate system (patent pending) makes it easy to customize grate configurations to produce a wide variety of finished materials. Grates are removed through an access door on the side wall of the 6700B.
- Impact Release System (patent pending). This important feature minimizes damage from contaminants in the feed material. The anvil and first grate open if a severe impact occurs, allowing the contaminant to be ejected. The system then re-latches to permit continuous grinding.
- Impact Cushion System (patent pending). Urethane cushions allow movement of the compression roll and anvil housing pivot shaft, cushioning impacts from contaminants in the feed material. Shear pins above the cushion and a sensing circuit that stop the engine help protect the shaft from damage in the event of a severe impact.
- Rotor Options. The 6700B includes a traditional "drum" style rotor for general applications, and a "pinned" style for high impact applications such as C&D.
Since 1982 Peterson has manufactured equipment for customers in over 20 countries. Peterson specializes in developing delivery and processing equipment that turns low-grade organic materials into high value products.
