[ 1 ] Rotor/knife: The rotor is a solid steel drum , precision machined to produce the requested chip size.
The straight knives are mounted with a special wedge system that while utilizing the flyweel effect of the rotor , lock and secure the knives.

[ 2 ] Counterknife: The counterknife support is divided into 2 parts; a stationary support locked in place, and a removable part to which the actual counterknife is mounted.
This construction forms a precision seat for the counterknife and allows for easy removal
of the counterknife.

[ 3 ] Infeed rollers: Machined and surface hardened ”pineapple style” infeed rollers stop when the rotor reaches its maximum load.
As the load decreases, the feed works starts up again.
This start/stop sequence eliminates overloads of the rotor.

[ 4 ] The rugged, heavy duty main frame and rotor along with the chrome nickel shaft and oversized roller bearings, are engineered to accomodate the heavy shock loads typical of drum chippers.
