Beltrami, MN — Sometimes adding grain storage and handling equipment at a cooperative’s grain elevators is just a matter of gratitude.
“The farmers have supported us over the years,” says Bryan Mueller, grain manager for West Central Ag Services’ branch elevator in Beltrami, MN (218-926-5522). “Their farms have been growing; we’re growing to continue to be able to meet their needs.”
According to Mueller, who transferred to West Central six years ago from its LLC with CHS in Hannaford, ND, that growth involved $35 million worth of new construction at the cooperative’s headquarters elevator in Ulen, MN and the branch in Beltrami.
At Ulen, the work included 2 million bushels worth of new upright steel storage, a 60,000-bph leg and reversing belt conveyor for both receiving and loadout, and the construction of a 3-million-bushel flat storage building directly over an existing temporary storage pile.
At Beltrami, 2017 construction included 1.6 million bushels of upright steel storage for wheat, a pair of 20,000-bph pits and legs, and a 2.6-million-bushel temporary storage pile for corn.
West Central took bids and hired Walt Johnson Construction, Alexandria, MN (320-763-9005), as general contractor and millwright for the bulk of the work at both locations.
“We’ve used Walt Johnson for three expansions at Beltrami, as well as projects in Ulen, including a new fertilizer plant,” says Mueller. “We’ve grown our trust in them over time.”
Other major players at the two locations:
Construction began in April 2017. Work was completed the following February in Beltrami and March in Ulen.
New upright storage at the Beltrami branch consists of a pair of 800,000-bushel Brock corrugated steel tanks. These tanks stand 101-1/2 feet tall at the eaves and 129 feet tall at the peaks.
These tanks have flat floors, outside stiffeners, 16-inch Springland sweep augers, radar-type level indicators, but no grain temperature monitoring cables for now. A set of six Brock 50-hp centrifugal fans supply 1/5 cfm per bushel of aeration through in-floor ducting.
New storage also includes a 2.6-million-bushel temporary storage system. It consists of a 330-foot-diameter ring with Hanson 16-foot precast concrete walls, safety catwalk, and screens built into the walls to admit air; ag lime floor; and a Warrior center fill tower equipped with four Rolfes@Boone 60-hp centrifugal fans.
A 30,000-bph overhead Hi Roller enclosed belt conveyor carries grain out to the pile, which is emptied using a portable open belt conveyor. When Grain Journal visited in mid-April, the tarp had been removed for reclaiming the corn that had been stored there, which appeared to be very clean.
West Central also installed a pair of Rice Lake pit-type 80-foot truck scales, one for inbound traffic and one for outbound. Trucks are routed through the property using a CompuWeigh SmartTruck automation system. (For more detail on the SmartTruck system, see page 66.)
In addition to the scales, West Central installed two new 800-bushel mechanical receiving pits. These feed a pair of 20,000-bph GSI receiving legs outfitted with a single row of Maxi-Lift 20x8 gray CC-MAX elevator buckets mounted on a 22-inch belt.
The legs deposit grain into a Schlagel 5-hole rotary double distributor. From there, a set of 30,000-bph overhead Hi Roller enclosed belt conveyors take grain out to the new storage or to the temporary storage pile.
The new tanks empty onto 60,000-bph Hi Roller enclosed belt conveyors in above-ground tunnels. These carry grain back to existing handling equipment.
At the Ulen site, Braseth Sales installed two more 105-foot-diameter Brock tanks the same size and similarly equipped to the new Brock tanks at Beltrami.
Mueller says West Central would have added a third 105-foot tank, but space limitations held the diameter on the third tank to 72 feet. This smaller tank holds approximately 400,000 bushels and stands 93-1/2 feet tall at the eave and 113-1/2 feet tall at the peak.
The tank also has outside stiffeners, flat floor, Springland sweep auger, level indicator, and no grain temperature cables. Like the other steel tanks built in 2017, this one is set up for 1/5 cfm per bushel of aeration using a pair of 60-hp Brock centrifugal fans. All aeration fans installed at Ulen are equipped with silencers to help with noise at the in-town location.
Grain reaches the new tanks via Hi Roller enclosed belt conveyors from three existing pits and legs, a 30,000-bph conveyor from a leg to the south and a 60,000-bph reversing conveyor from two pits in the existing concrete house. Sets of 30,000-bph and 40,000-bph enclosed belt conveyors are mounted atop the new tanks to allow all three of the existing pits to transfer grain to the new storage at once.
The tanks empty onto a set of 60,000-bph above-ground Hi Rollers running back to existing legs. Once elevated, grain may be run through a pair of 50,000-bph J&D gravity screeners with external bypasses before being transferred via a reversing 60,000-bph Hi Roller enclosed belt conveyor to an existing bulkweigher for loadout.
Directly across Washington Avenue from the new storage, Greystone Construction constructed a flat storage building over an existing temporary storage bunker. The newly enclosed structure measures 292 feet wide by 465 feet long and is 98-1/2 feet tall at the peak.
The new building currently holds 3 million bushels using an existing overhead conveyor that filled the original temporary pile, and with the addition of more spouting, will hold a planned 3.5 million bushels.
The upgraded flat storage has an asphalt floor and a set of 30 10-hp AIRLANCO axial aeration fans. The building is set up with doors to admit front-end loaders and semi-trucks for unloading.
