4710D Horizontal Grinder

4710D Horizontal Grinder


The 4710D is a track mounted horizontal grinder designed for high-volume producers with very demanding end-product specifications. Boasting 18 inches (46 cm) of ground clearance—this model is particularly suited for land clearing operations or other applications where mobility and frequent moving is desired. Track mounting also reduces material handling costs in conventional recycling yards as well.

The 4710D is powered by a Tier IV Caterpillar C18 engine rated at 755 horsepower (563 kW). A Tier II, 765 horsepower (570 kW) engine is also available. It features Peterson’s Adaptive Control System, which controls all components of the feed system to optimize output. This system senses variations in the engine load and adapts the operating parameters to produce the maximum amount of material at all times.

Peterson’s three-stage grinding process with an up-turning rotor and large grate area enables the 4710D to produce materials to exact specifications. 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.

The IQAN control system provides the operator with complete engine and system parameters to simplify set up to efficiently operate the unit.

3-Stage Grinding Process Provides Faster Reduction

3-stage grinding process provides better fracturing of material and a more consistent product, giving you just the product your buyers are looking for.

The Impact Release System Protects Your Investment

Peterson’s patented Impact Release System’s air bags provides uniform grinding and protection from contaminated feedstock, a feature unique to Peterson grinders.


The Second Line of Defense: The Impact Cushion System

Urethane cushions and shear pins help protect the mill from catastrophic damage in the event of a severe impact from contaminants in the feed stock.
