A maize sheller is a machine that separates maize grains from the cobs.
It is a motorized, power-driven device that uses a rotating cylinder with pegs to rub the cobs against a concave surface, which removes the grains.
Maize shellers are available in a variety of sizes and capacities, from small, hand-operated machines to large, industrial machines.
They are used by farmers, processors, and other businesses to process maize for human consumption, animal feed, and other uses.
