2750C Electric Grinder

2750C Electric Grinder

Overview

The 2750C electric horizontal grinder is ideal for operations that can take advantage of stationary or semi-stationary operations. Powered by a single 400, 500, or 600 horsepower (300, 375, or 450 kW) electric motor, the Peterson 2750C Electric Horizontal Grinder 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 of up to 44 inches (112 cm) high, the 2750C Electric Horizontal Grinder can reduce a diverse range of raw materials.

Our quick-change multiple grate system makes it easy to customize grate configurations to produce a wide variety of finished materials.
