Model 222B, Low Frame with Aspirator
(Used to process shelled corn, wheat and oat groats)
Serial #M01043, December 1999
| The Model #222B Kelly Duplex Corn Cutter and Grader is a two
screen grader combined with a grain cutter head that processes up to 7,000
pounds per of shelled corn per hour, and produces two grades of sized
particles with the fine meal screened off and removed with air aspiration.
Standard equipment includes a 7-1/2 HP motor drive, a built aspiration fan
and a cyclone separator for collection of fine particles. This unit
combines cutting, grading, cleaning and polishing operations in one
compact machine that produces high capacity at low maintenance and power
costs. The final product is accurate, uniform and of unusually excellent
appearance.
 Operation
is simple and trouble-free. The grain first enters the cutter unit where
it is cut by a set of high- speed knives. When it has been reduced to
proper size, it passes through a perforated screen and drops onto a
grading shoe. Here, a rotary oscillating action sifts the grain through
screens of different mesh and separates it into grades. The aspirating
equipment then cleans and polishes each grade, removing hulls and trash.
Optional equipment includes a cutter head with a built-in by-pass which
permits whole grain to by-pass the cutter chamber and go directly to the
shoe for cleaning, and a magnetic separator installed in the inlet hopper.
The carefully constructed wooden grader shoe is
suspended to the integrated machine steel frame with isolation springs in
four places, as illustrated above. The single motor drive, which operates
all functions of the Kelly Duplex Corn Cutter and Grader, is illustrated
in the photo to the right. Overall operation is very simple with minimum
maintenance. |
