5050H Electric Whole Tree Chipper

5050H Electric Whole Tree Chipper


The stationary, electric Peterson 5050H Delimber Debarker Disc Chipper produces high quality low bark content chips for wood pulp and pellets, processing whole trees in one continuous operation. Equipped with a large feed throat, the 5050H can accept up to a 23-inch (56 cm) diameter single tree or multiple smaller stems.

The 5050H can be configured with a three or four pocket disc, with several optional sheave sizes to make precisely the chip you need.

The standard three-pocket disc produces chips from ⅝ to 1 ¼ inches (16–32 mm) long, while the optional four-pocket disc produces chips from ½ to 1 inches (13–25 mm) long.

Chipping production rates up to 150 tons (136 tonnes) per hour can be achieved depending on chip size and wood characteristics.

Peterson’s heavy-duty 66-inch diameter, 4 ¾ inch thick (168 x 12 cm) chipper disc has replaceable ½ inch (13 mm) wear plates.

Traditional babbitt-type knives or Key Knife components are available.

The stationary 5050H can be configured from 600 to 1000 hp (447–745 kW) at the disc depending on the needs of your application. An additional 600 hp (447 kW) electric motor powers the needs of the hydraulic system.

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