5700D Horizontal Grinder

High Production Waste Wood Grinding

5700D Horizontal Grinder


The 5700D Horizontal Grinder is designed for high-volume producers with very demanding end-product specifications.

Powered by a Tier II or Tier IV Caterpillar C27 1050HP (772 kW) engine, or an optional Tier II or Tier IV 1125hp (839 kW) C32 engine, the 5700D provides the highest power to weight ratio of any Peterson grinder.

At 82,000 pounds (37195 kg), the 5700D is designed for operations requiring high production and frequent moves between jobs. With a feed opening of 60 x 40 inches (152 x 102 cm) combined with Peterson’s high lift feed roll, 5700D Horizontal Grinder can readily reduce a wide range of material including stumps.

Peterson’s three-stage grinding process with an up turning rotor and large grate area enables the 5700D to produce materials to exact specifications.

The 5700D Horizontal Grinder IQAN control panel features a large LCD display that provides the operator with the information needed to efficiently operate the unit. System pressure transducers and remote monitoring capability simplify set up and provide complete engine and system parameters. The 5700D can be operated by wireless remote from the comfort of your loader.

The 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 access door on the side wall.
