Concept
The machine is easy to operate, easy to maintain and reasonably portable. It can be used anywhere by virtually anyone. It is also a simple matter to switch from degraining to milling by unbolting one appliance and attaching the other.The Mill function has the capacity to mill 3 lbs. per minute of any type of grain or coffee beans. The most common use is for milling yellow maize, soya beans, and other elements that make up animal feed. The Corn Degrainer for example is used postharvest and easily degrains 1200 to 1500 lbs per day.
How to Build the Mill
The Mill
The Chassis
Weld the bike frame in place, lining up the sprockets so the chain will run straight. You will need to bend the drive-side chain stay in order to clear the chain. To form a better bond, the frame is flattened and bent before welding to the chassis. File any sharp edges and paint.
