MACHINE DESCRIPTION
3.1
Constructional design
3.1.1 Rotor bearings
The rotor is running on oversized spherical roller bearings. The steel housings are
flanged and spigotted into the chipper housing side plates. Seals are lip type.
3.1.2 Feedroll carrier pivot
The feedroll carrier pivot connects the pivot/cradle with the machine housing and it is
formed by heavy spherical roller bearings in flanged steel housings.
3.1.3 Lower feedrolls and bearings
The feedrolls with special tooth profile are running in heavy spherical roller bearings
in flanged steel housings, spigotted in the housing sidewalls. Seals are lip type.
The teeth of the feedrolls are hard tipped to prevent wear.
The feedrolls are driven by a gear motor driving the first feedroll behind the rotor with
roller chain drives from roll to roll. These chain drives are protected by an oilbath type
chain case, completely enclosed, ensuring proper lubrication while keeping out dust
and dirt.
3.1.4 Upper feedrolls and bearings
These feedrolls are similar to the lower feedrolls with the exception that they are
mounted in a carrier, which pivots up and down to adjust for different sizes of pieces
to be chipped.
Drive is by gear motor to the first feedroll at the inlet.
