Peterson 2750D Electric Horizontal Grinder

Overview

The 2750D 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 2750D 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 a feed opening of 60¾ x 32 inches (154 x 81 cm) combined with Peterson’s high lift feed roll for an optional opening up to 44 inches (112 cm) high, the 2750D can reduce a diverse range of raw materials.

Applications

Organic Recycling

Green waste recycling is fresh or biodegradable waste material including grass, leaves, plants and tree trimmings that can be diverted from landfills for recycling. This method is best used to produce compost for use on gardens, lawns, erosion control projects and agricultural crops.

Mulch

Organic mulch is a product that can decompose, providing nutrients to the soil over time. It can be made from a variety of materials, typically organic, but not exclusively.

Wood Waste Recycling

Wood waste is the second largest category of construction and demolition (C&D) debris, and accounts for 10% of material added to landfills annually.
Learn More
Biomass

Biomass is an energy source derived from renewable and sustainable organic materials to create electricity or other forms of power. Horizontal grinders and drum chippers are highly productive machines for creating biomass.

Asphalt Shingle Recycling

Asphalt shingle grinding is the process of making recycled asphalt shingles (RAS). RAS is produced by grinding asphalt roofing shingles to a small spec, generally under 3/8” to salvage the valuable asphalt and sand.

Natural Disaster Cleanup

Natural disasters such as hurricanes, tornadoes, earthquakes, fires or floods create debris that must be cleared to restore affected areas. This type of debris can be green waste (such as tree limbs), furniture, drywall or entire structures that have to be demolished and recycled.
