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, augured
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, 1/2" energy
chip. Bottom right, 3/4" pulp chip. Top right, 1" landscaping chip. |
| |
|
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. |
|
|
|
|
Ease
of Operation
The
low feeding point
ensures effortless feeding of the chipper, allowing the operator to 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. |
|
|
|
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. |
|
|
|
|
Interchangeable Feed Chutes
The CH 260 chipper
can be fitted with 4 different feed
chutes. The chipper can therefore be used for a variety of
tasks. |
|
All feed chutes are mounted in
the same brackets on the chipper by the bolt-on method. The feed chutes
are mounted on a hinge, so they can be turned to the side
for easy access to the anvil and the knives. There is a lifting loop in
the balance point so they can be lifted off and on with machinery. |
|
|
|
|
F 250 This
feed is featured in the picture on the top of this page on the right
hand side. A control bar runs on top of the feed chute.
The feed can be interrupted by the control bar. The wide feed chute is
used for slabs, poles and other materials that need not be compressed. |
|
|
|
|
|
HF 231 This
feed has two hydraulic motors which power the feed rollers. The
feed rollers can be powered by hooking up to the tractor's hydraulics
or the chipper can by equipped with an independent hydraulic
system which is powered from the chipper axle. |
|
|
|
|
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 operator can select to start
or stop the feed from the control bar on top of the feed
chute. The control also has a reverse position to push back the material
inside the feed chute. The hydraulic feed chute is close to the ground
so quite heavy trees can be manually fed into the chipper. The low
feeding angle also enables the chipper to be fed with knuckle boom
loaders. |
|
| |
|
Round wood, Slabs and
Brush.
The Valby CH260 can chip 10
1/4" diameter round wood. The wide mouth opening also
enables wide slabs to be chipped. The chippers mouth opening is at it's
widest at 24". Brush and other bushy material is chipped best when the
chipper is equipped with a hydraulic power feed. |

The Valby CH260 can chip 10
1/4" diameter round wood. The wide mouth opening also
enables wide slabs to be chipped. The chippers mouth opening is at it's
widest at 24". Brush and other brushy material is chipped best when the
chipper is equipped with a hydraulic power feed. |
|
| |
|
Drop
Spouts
Two different types of
drop spouts are available for the Valby chippers. The angle of the
spouts are steep so the material is gravity fed into the chipper.
Drop spouts can be used when
the material is transported to the chipper by a conveyor or if the size
of the material to be chipped is small. These kinds of applications are
common in pallet mills and furniture factories. |

|
Safety Features
The Valby Chippers
do not have knife motion toward the operator - this reduces the risk of
loose material flying back through the feed chute.
The discharge height is 9 1/2
feet (optionally 12 feet) above ground so the discharge is above eye
level. To accomplish safe operation in various wind direction, the
Valby chipper's discharge direction is adjustable 360 degrees. |
|
|
The safety bar on top of the F 260
feed chute releases a
flap which covers the feed opening. In the hydraulic feed model, one
can not only stop the in feed, but it can also be reversed. The Valby
chippers also have several
noise-reduction features,
such as the discharge opening is above ear level and can be
adjusted away from the operator |
|
|
The noise coming up
through the feed chute is greatly reduced by the flap which
covers the feed chute. The hydraulic feed rollers also return to a
position which covers up the feed chute. |
|
| |
|
Shredding Paper
Both ends of the knife are
covered, so twigs or other material do not get hung up on the knives.
This enables the chipper to also be used for shredding paper. |
