1961 RANCO was incorporated. RANCO derived its name from the main investor, Ray A. Nation (RAN) and Company (CO). Hence RANCO was formed. The other two investors were Glen Gillett and Paul Krile.
1962 RANCO introduced a mobile mounted blending and spreading unit
A stationary unit was also designed later in 1962.
1963 The first stationary Multi-Blender was produced that included fiberglass tube augers to discharge away from each bin (the first meter units).
Owners Ray A. Nation and Glen Gillett did not survive a plane crash. Paul Krile assumed primary ownership and leadership responsibility.
1964 Railcar and truck unloaders were developed to receive bulk fertilizer.
1965 First bucket elevator built. The original Ranco leg was built out of wood and steel.

1968 Paul’s Four Nubbins quartet went on a USO tour
1969 Flinger developed for overbin conveyor.
First high capacity barge receiving system installed in Augusta, Arkansas.
Overbin belt conveyors now available in 16” wide versions.
1970 Electronic drives replaced the mechanical drive system on the multi-blender. This change increased system capacity by 2 to 3 times.
1971 Blender bins were changed over to fiberglass as well as the u-trough blend auger behind the blender.
Added large diameter drive roller and gravity take-up’s to the now standard 16” wide belt conveyor to reduce belt tracking and training problems.
Ranco purchased the local Quaker Oats Elevator. The purchase was made so there was a place to test the fertilizer handling and blending equipment. Ranco maintained the day to day operations of the elevator and participated in the grain business until it was sold in 1989.
1972 200 ton per hour equipment was developed to accommodate more barge unloading terminals.
1973 Changed the electronic blender drive system to a more sophisticated control system that allowed motor control accuracy of ¼ of 1%.

2004 Development of high capacity roller conveyor. The roller conveyor allowed us to convey material further than our standard slider bed conveyor. Up to 800 TPH
2007 The former Simonson Ironworks building in Sioux Rapids was purchased and tagged “Rantec”. Ranco began doing much more of its own fabrication.
