Production
The
solid construction of the rotor enables trees up to 10
¼" in diameter to be chipped. Chip size and tree size determine
production. The production ranges from 13 to 52 cu. yards per
hour or approximately 3 to 15 tons of chips per hour. The chip
size produced determines how fast the trees are pulled into the
chipper. When producing ¼" chips the tree will feed in about one
foot per second. The feed is about 3 ft. per second for 1/2"
chips.
The feed of the Valby
chippers is about 10 ¼" at the anvil. The maximum width of the
opening is 24". The thickness and form of the slab will
determine how large a piece can fit in.
The hydraulic feed restricts
the slab width to 10 ¼" as the slabs are fed in on a straight
angle to the anvil.

Spherical Roller
Bearings
The high
quality bearings enable the chipper to be used at PTO speeds of
up to 1000 RPM. This allows high production and powerful chip
discharge, which is needed when chips are blown into 40 ft. long
trailers.
Hydraulic Power Feed
The
hydraulic motors transfer to the feed rollers up to 10
HP of dragging power to pull in the material. Christmas trees or
other bushy materials feed in with little or no pruning. Small
trees can be fed in with branches and all.
The bottom feed
roller is fixed. The top roller is spring loaded. The top roller
climbs on top of the material and starts to drag it in. The top
roller pushes in the branches against the bottom roller and the
branches get squeezed tight so they fit through the chute. The
turning speed can be adjusted from a knob on the hydraulic
valve. The forward, stop, and reverse of the feed rollers
are controlled by the control box, which is shown above. |
