Power Recommendations
1. The horsepower recommendations are for augering reasonably dry grain. High moisture grain above
(15%) will require greater power if maximum capacity is to be maintained. The maximum possible
capacity will be less with high moisture grain that with dry grain. Use and electric motor of the correct
size that operates at 1750 RPM. DO NOT use a motor size that is greater than what is shown for the
largest bin size in the column.
2. Consideration should be given to the proper size auger for a batch drying or any intermittent type
operations. When augers are stopped and restarted under full load, it may result in damage to the
auger. Using a larger diameter auger and reducing its load level will be far better than subjecting a
smaller diameter auger to big loads. If an auger is kept from absolute filling, it will make start-up
easier and will convey more efficiently.
NOTE: The auger capacity can fluctuate greatly under varying conditions. Moisture content, different
commodities, amount of foreign matter and speeds all play a part in the performance of the
auger. Twenty-five percent (25%) moisture may cut capacity by as much as forty percent
(40%) under some conditions.
