Hi, in my opinion, the rotor should look like a star shaped but having three protruding edges and very blunt; It's like taking a view of tripod stand but from the base. The edges rub the groundnut pods on the screen mesh causing it to break apart and groundnut seeds falls through the mesh.

Can you attach any image of it. I am willing to have great depth of details on the image.

You can design something similar to this.

Thanks :)
