Uniform Chips
All Valby CH 260 models
have the same chip mechanism. The chips have to pass through TWO
sets of blades and an optional crusher screen before they are blown
out from the chipper. This chip mechanism produces exceptionally
uniform chips which can be, for example, augered without further
screening.
Double Disc Rotor
The boxed double disc
rotor provides superior rigidity. The disc weighs 560 lbs.
and has a diameter of 41". The rugged rotor houses three full-size
11.8" wide knives. The full-size knives are the key to the Valby
chipper's high production.
Adjustable Chip Size
The chip size is
continuously adjustable between ¼" and 1" length. This
range covers almost all possible uses of wood chips. Some typical
chip sizes are shown below. Bottom left is ¼" animal bedding. Top
left, ½" energy chip. Bottom right, 3/4" pulp chip.
Top right, 1"
landscaping chip.
Screens
By the use of screens one can
further increase the uniformity of the chips. The screens are
mounted so that they prevent discharge of material which does not
for reasons of size, or form, go through the screen. The material
is then reduced to size by passing it through two sets of secondary
cutters.
Ease of Operation
The low
feeding point ensures effortless feeding of the chipper.
The operator can stand with
a straight back. The discharge is
adjustable 360 degrees. The chipper stands up by itself on the
ground and is easy to hook up or remove from the tractor.
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 1/4" 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. |
