1710D Horizontal Grinder


Heavy duty and mobile, the 1710D Horizontal Grinder can readily reduce a wide range of materials.

The 1710D’s large feed opening, measures 54″ x 27″ (137 x 69 cm). When boosted by Peterson’s high-lift feed roll, the feed opening’s maximum lift of 41.5 inches (105 cm) can tackle the largest of feedstock, and allows excellent accessibility to the rotor for maintenance.

The 1710D Horizontal Grinder is equipped with a Caterpillar Tier IV C9.3B 455 hp (Stage V, 339 kW) engine, or an optional, export-only C9.3B Tier III, 415 hp (309 kW) engine. At 46,500 pounds (21,092 kg), it is one of the lightest of Peterson’s grinder series, and is easily transportable.

Peterson’s Adaptive Control System, featuring a fully adjustable feed system, is optimized for a wide range of materials. The 1710D control panel features a large display that provides the operator with complete engine and system parameters to simplify set up and efficiently operate the unit.

The 1710D also features Peterson’s patented Impact Release System, to protect the machine against ungrindable materials, a feature unique to Peterson horizontal grinders.

The 1710D Horizontal Grinder features a quick-change multiple grate system, making it easy to customize grate configurations. Grates are removed through an easy-access door on the side wall. With Peterson’s patented up-turn rotor, and heavy-duty bits, and robust anvil, the 1710D has an exceptional wear life and accurate product sizing.
