Forage Cuber Features Go Anywhere Portability

Forage Cuber Features Go Anywhere Portability FORAGE HARVESTERS Forage Harvesters (31F) 7-6-23 "Other mills will cube but this one is the Rolls-Royce of cubers," says Wyoming rancher Bob Clark, of Kinnear, who has developed a cubing mill ù completely portable ù that he thinks will solve many biomass handling problems. It will dry anything from up to 65% moisture down to 10% moisture and pack it into 1 1/4 inch square bricks about two inches long. If the material is at 65% moisture it will handle 4-5 tons/hr. input. It peaks out at the mind-boggling rate of 15 tons/hr. when cubing material is of only 10-12% moisture content. The key feature of Clark's KR3 high-capacity cuber is that it's portable and can be moved to a sawmill, farmstead, or other location where it's needed. It requires 60 gal. of No. 2 diesel fuel per hour, equaling an input of 7,680,000 btu per hour. But, for example, the cuber can convert 20,000 lbs. of sawdust that is bulky and unmanageable into neat cubes in an hour. And this amount of sawdust contains about 200,000,000 btu of energy. So, with this new, efficient manner of handling, waste sawdust could be used in fuel gasifiers, which Clark thinks will ultimately heat our homes. The material to be cubed is lifted into the tub of the hammer mill by a knuckle-boom-type crane that has changeable grabbers and a reach of about 30 feet. This method of filling the tub grinder would work best with bales, but the crane will also load grain or sawdust. These materials could also be augered into the tub. Either way, practice has shown that the mill can handle material as fast as it is filled.
