Peterson Introduces the New 6700D Horizontal Grinder

August 21, 2015


EUGENE, Ore., November 7, 2014–Peterson Pacific Corp., has introduced the all-new Peterson 6700D is Peterson’s largest horizontal grinder, and is designed for operations that need the most durable, highest output machine. Powered by a 1125hp (839 Kw) Tier II, Caterpillar C32 engine (or an optional Tier IVi Caterpillar C32 engine), the 6700D is designed for the toughest jobs.

With a feed opening of 66 x 50 inches (168 x 127 cm), the 6700D can even process large stumps that used to be reserved for tub grinders! The grinder is particularly suited for land clearing operations or other applications where mobility is desired.

With the R+ package, the 6700D can be configured as a mid-speed grinder to handle heavily contaminated piles, or a high speed grinder for typical land clearing operations. Peterson’s three-stage grinding process with an up turning rotor and large grate area enables the 6700D to produce materials to exact specifications. Our quick-change multiple grate system makes it easy to customize grate configurations to produce a wide variety of finished materials. Grates are removed through an enlarged access door on the side wall of the 6700D.

The 6700D features Peterson’s Adaptive Control System, which controls all components of the feed system to optimize output. This 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 rollers, slows when the load is high, and reverses if the engine speed drops. It even monitors the engine temperature and varies the cooling fan speed to minimize power usage and reduce fuel consumption.

Unique to Peterson Grinders is our innovative latching Impact Release System, which minimizes damage from contaminants in the feed material. The anvil and first grate open on a severe impact, allowing the contaminant to be ejected, and then re-latch to permit continuous grinding.

Peterson specializes in developing delivery and processing equipment that turns low-grade organic materials into high value products.Peterson 6700D Horizontal Grinder Clean Shot
