The Design And Fabrication Of A Iron Shelling Machine

ABSTRACT.

A machine for corn Sheller is highly and greatly needed for consistence of usage of corn in local and international levels.

With regards to this indispensable need, a corn-shelling machine is designed which operates to remove the corn grains and leaving the cobs intact.

In attainment to this design objective and aims, a proper considerations was given to the machinability factor which includes, installation, simplication, durability, choice material operational efficiently serviceability of the masculine low costing and prolonged life span when operates with utilization with minimal down fine  

The design details are given includes such items as materials and their characteristics. Adaptation methodology the parts relation with the whole device and the effect of the finished product upon which an inquisitive mind can make collection of fact in future which related to this project.
