Peterson 4750D Electric Horizontal Grinder

Overview

The 4750D electric horizontal grinder is ideal for operations that can take advantage of stationary or semi-stationary operations.

Powered by a single 600 horsepower (450 kW) electric motor, the Peterson 4750D has plenty of power. Since electric power costs are typically much lower than diesel fuel costs, electric power may just be the answer for increasing your profits.

With standard feed opening of 60 x 38 inches (152 x 97 cm) combined with Peterson’s high lift feed roll for an optional opening up to 53 inches (135 cm) high, the 4750D can reduce a diverse range of raw materials.

Applications

  • Wood Waste Recycling

    Peterson horizontal grinders are ideal for wood waste recycling applications. Because of the limited options to reuse building materials or wood recycled from demolition efforts, reduced wood waste can be recycled to make biomass, bedding material, mulch, or compost.

  • Municipal Solid Waste (MSW) Recycling

    Peterson horizontal grinders with the R+ package are an ideal tool for MSW reduction. R+ equipped Peterson horizontal grinders turn the rotor at a slower speed and have heavier duty internal components to handle the tramp metal often found in this application.
