
Loading rolls
These rolls take over loaded materials and move them to the chipping wheel. Their
speed can be regulated according to the given sort of material and expected results
– chips.
Both rolls are ribbed and enable loading of materials and also pulling them out at
reverse turning if necessary (chipping wheel overloaded). Both rolls are powered
by a hydraulic motor.
If required, both rolls are outwards movable in order to adapt working to the
material to be loaded.
This machine is equipped also with loading speed regulation with sensing actual
speed of the chipping wheel. Assessment of actual speed and following speed
regulation are controlled by the NOSTRESS unit.

Chipping wheel
It is a steel disc serving also as a flywheel for absorption of shocks while chipping.
This wheel is put in ball bearings; a drive pulley is fitted on its shaft. The wheel is
equipped with two blades for cutting of loaded materials. Vanes welded on its rear
side serve for ejecting chips in the discharge duct.
The chipping wheel is installed in a rigid frame and protected by a steel plate. Its
protective shield consists of two parts and particular parts are bolted together. By
safety reasons the upper part is protected with a terminal switch for turning the
drive off if the shield was opened or got loose.

Discharge duct
This duct continuously extends the chipping wheel shielding and serves for
directing the ejected chips. The duct is turnable and its end piece (tilting gate)
serves also for setting the range of ejected chips.
Frame
This machine is attached to a rigid frame welded from hollow-space profiles. In the
front part there is a three-point hitch welded and intended for coupling to a tractor.
In the bottom frame part there are a belt gear and the machine input shaft.
