The main aim of this project is to re-design the existing machine for better efficiency and merging the nut separator machine to shelling machine. This machine can separate the groundnut from the plant and separate the nut from the shell. This machine is fully fabricated with mild steel hence it makes it cost efficient and it is more compatible than the previews designs. It consists of two drums, motor, frame, bearings, fan, chain, and sprocket. The major priority of this project is to shell nuts more efficiently and effectively. In this project two drums are vertically placed one above other, where the top drum is used to separate the nut from the plant and the lower drum is used to separate the but from the shell. This is achieved by the shearing action inside the drum between the crusher and the drum. This paper describes the design of various components or parts of groundnut shelling machine. This project involves process like the design, modeling, and analysis components etc. The performance of the machine is evaluated in terms of capacity, the rate of feed and efficiency
