Towed Mill Makes Straw Pellets
German manufacturer Krone developed the Premos 5000, a mobile pellet harvester and stationary mill that harnesses the potential of straw, which is often abundant in harvested fields. The machine presses the material into top-quality, high-fiber pellets, ideal for bedding, animal feed and fuel right in the field.
“The towed unit requires a 350 to 450-hp tractor to pelletize hay or wheat, barley, oats and canola straw,” says Krone Product Specialist, Niklas Beindorf. “The material must be below 16% moisture content for optimal efficiency.”
A 2.5-m wide pickup gathers the input material and directs it to a feed rotor where a belt conveys it through two large, contra-rotating drums. The roller drums press the material at extremely high pressures through holes in the opposite roller, producing 16 mm diameter pellets. These pellets then drop into the drum’s interior from where they travel by auger to an elevator, which transfers them to another drum for debris and dust removal. The finished pellets are conveyed to a 5-ton hopper where a blower cools them.
The Premos 5000 can pelletize between 5 and 6 tons per hour. Rear liquid tanks hold water and oil that can be dispensed into the hay or straw for optimum moisture and pelleting results.
“It’s not necessary to constantly add water and oil as it’s only needed for a short moment,” Beindorf says. “When the resistance in the die rollers is broken, the liquid can be turned off. The physical rule behind this is that material with higher moisture content is easier to compact, while dry material is more slippery and difficult to press.”
Cab-mounted monitoring systems are ISOBUS compatible and offer a 5.7, 8 or 12-in. touch display screen.
The Premos 5000 can also be operated as a stationary machine. A foldable bale feeder with automatic twine removal for large square bales can be added.
The versatile pelletizer is manufactured in Spelle, Germany, where all Krone Ag machines are built. They’re currently available to North American farmers.
