This allows Rotochopper owners to diversify into chip markets without the hassle of a typical chipper conversion package.
The new knife chipper package allows horizontal grinder owners to chip and grind with a single machine. The chipper mount uses the same patented mounting system as a grinder tooth mount. The chipper knife package is a bolt-in option that works with the standard replaceable mount rotor for the Rotochopper B-66 and B-66 E. This chipper knife system makes it simple to diversify into chipping applications without a complex conversion kit or a second machine. Rotochopper indicates that unlike other grinder to chipper conversion packages, the Rotochopper system is more simple and reliable.
To switch from grinding to chipping, the operator does not need to swap the whole rotor drum or assemble a complex overlay onto the grinding rotor. The operator simply swaps the grinder tooth mounts with chipper knife mounts. A single operator can switch from grinder teeth to chipper knives quickly and easily. No rod pullers or other specialized tools are required (only a torque wrench); there is no need to swap rotors, re-align sheaves, or re-tension drive belts; and there are only two bolts per knife mount and two bolts per knife clamp.
Knife replacement costs are reduced due to the knife chipping inserts being indexable (reversible). By loosening the knife clamp bolts, the operator can flip the knife to utilize a second chipping edge. A Key Knife insert uses significantly less steel than a traditional chipper knife, making handling and replacement easier. The chipper blade on each mount is much narrower than traditional chipper knifes, helping to minimize the maintenance costs that can result from rocks, metal, and other contaminants. Key Knife specialises in chipping, flaking, and planing systems that maximize production rates and product quality, while minimizing maintenance costs. Key Knife products are used by sawmills, pulp mills, loggers, biomass fuel producers, OSB plants, particleboard plants, and many other companies around the world.
