Use Of Torque
Just as brush chippers are classified or ranked on chipping capacity by the linear height of their feed opening, there is also more to the numbers associated with drum diameter, drum speed, and engine horsepower when determining the true performance of a machine. One has to examine how that engine horsepower is utilized across its rotational components. Bigger is not always better.
Put A Better Spin On It
The VORTEX® chipping system separates and isolates the functions of chipping and throwing to each take full advantage of the maximum available horsepower and torque delivered from the engine in their own individual way. In a conventional drum system where the drum is bound to both chipping an throwing functions along the same rim diameter, torque/power from the engine is surrendered at the expense of having to spin the drum faster to adequately throw chips, especially if the drum is "oversized". Rotational cutting force at the knife tip increases the closer you get to the axis of the drum. With a "right-sized" drum where the diameter and RPM are not physically tied to throwing capability, less horsepower and less fuel are required to generate a greater cutting force at the knife tip. Mounted independently along the same shaft of drum in the patented VORTEX® chamber, the disc-shaped impeller will have increased leverage, inertia (flywheel effect), and rim speed for throwing.
Separation of chipping and throwing functions for better performance
The VORTEX® design offers a more dialed-in drum chipping ability with segregated throwing mechanics. Benefits include better use of engine horsepower/torque, faster engine recovery times during auto-feed stops, and better overall performance when it comes to both chipping and throwing. A VORTEX® chipper naturally and positively chips like a drum, and throws like a disc -- allowing operators to experience the "best of both worlds" in one machine.
