The Peterson model 4750B Horizontal Grinder is an electric powered version of the popular model 4700B trailer mounted Horizontal Grinder. Powered by twin 300 or 400-horsepower electric motors, the 4750B is ideal for operations that can take advantage of stationary or semi-stationary operations. Electric power costs are typically much lower than diesel fuel costs.In today’s changing economy, electric power may just be the answer to increasing your profits.

Peterson’s three-stage grinding process with an up turning rotor and large grate area enables the 4750B 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 of the 4750B.

Unique to Peterson Grinders is our innovative latching Impact Release System, which minimizes damage from contaminants in the feed material. The anvil and first grate open on a severe impact, allowing the contaminant to be ejected, and then re-latch to permit continuous grinding.

Another major innovation on the 4750B is Peterson’s Impact Cushion System. Urethane cushions allow movement of the compression roll/anvil housing pivot shaft, cushioning impacts due to contaminants in the feed material. Shear pins above the cushion and a sensing circuit that stop the motors help protect the shaft from catastrophic damage in the event of a severe impact.

Rotor options include a “drum” style rotor for compost/mulch applications, and a “pinned” style for higher impact or contaminated applications such as land clearing and construction & demolition (C&D).

Peterson specializes in developing delivery and processing equipment that turns low-grade organic materials into high value products.
