6750D Electric Grinder

Overview

The Peterson 6750D Horizontal Grinder is the electric powered version of the popular trailer mounted 6700D. Highly productive and efficient, it hits the “sweet spot” in the Peterson grinder product line. Powered by twin 600 HP (450 kW) electric motors with either soft-start or Variable Frequency Drive (VFD) starter control packages, the 6750D is ideal for stationary or semi-stationary operations. Electric power costs are typically much lower than diesel fuel costs, and in today’s changing economy, electric power may be the answer to increasing your profits.

With an internal drive compression roll and a 66 x 50 inch (168 x 127 cm) feed opening, the 6750D Horizontal Grinder can handle the requirements of your daily grind.

The 6750D Horizontal Grinder features Peterson’s Adaptive Feed Control System, which controls all components of the feed system to optimize output. This system senses variations in motor 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 6750D Horizontal Grinder to produce materials to exact specifications. The 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.

Since 1981, Peterson has specialized in the developing of delivery and processing equipment that turns low-grade organic materials into high value products.
