Silo unloader – Nordic 215/880 SK
Ring drive silo unloader - Nordic 215 - Ideal for small diameter silos
Unloader (with offset suspension arms)
Whether with a torque arm (outrigger arm) or a torque chain (shown here with a torque chain), the Nordic 215 silo unloader allows you to get the best results !
Distributor (with regular suspension arms)
To achieve an uniform distribution, it is crucial to keep the silage flowing evenly at the silo wall, forming a slightly inverted cone as filling progresses all the way to the top.
Electrical power is transferred from stationary to rotating part of the machine by extra-large brushes and thick copper alloy rings (CSA approved)
The heavy chipper wheel is made of ductile iron to resist shocks. Six self-sharpening hardened steel blades remove silage that clings to the wall.
High capacité blower
The 26'' high capacity blower with 3 stainless steel adjustable paddle rotating at 1,225 RPM for 8,330 feet per minute tip speed.
Ring drive Transmission (guards removed)
A positive ring and gear drive system provides steady, even cutting under all condition. Sprocket is driven by a 100:1 worm gear reduction on a shaft from the auger gear box.
Independent power ring drive (guards removed)
A reliable industrial coupling between motor and the 500:1 gear box assures positive drive. This model require less power during distribution.
A heavy flange coupling between auger and gear box prevents auger from seizing to transmission output shaft. Efficiency: 97 %
The blower features 3 stainless steel adjustable impeller paddles that can be set in a swinging or fixed position
Cantilevered pressure wheel holds the chipper wheel tight against the silo wall
Loaded with sharp cutting knives, the big 10'' auger delivers a steady stream of silage to the impeller for high capacity output
Providing the power to the heavy-duty auger and knives in frozen, hard pached silage requires a heavy-duty gear box. Rated: 20 HP

Three 5/16” galvanized aircraft type cables support the unloader from 3 widely spaced points which result in a lovel cut from top to bottom
The drive ring’s large diameter along with wall to wall suspension arms guarantee the perfect equilibrium of the machine without counter weight that has to be adjusted every now and then to match silage conditions. Made of 3/16” thick steel, the 3 ring segments feature a big 9′ diameter on the 12′ to 20′ models. They are reversible giving them twice the durability. Double 48” long splice plates provide rigidity to the whole assembly. On the 24′ models, ring segments are beefed-up and make a large 11′ diameter ring for a stable and well-balanced machine.
The massive 10” heavy-duty auger made of 1/4” thick flighting welded on a 4” O.D. tube for rigidity. It is double flighted at the chipper wheel and to allow the machine to run smoothly in frozen and hard-packed silage. Sharp hardened knives can be installed on auger to chop up to toughest material. Coupled to the gearbox by a 3-bolt flange coupling, the auger assembly is easy to remove.
