Gr8 Technology
You will not use an electrical motor in your model, but will rather turn the handle of a crank by hand. This rotational movement should be changed into a reciprocating movement so that the grain will be crushed, like hitting it with a hammer. The mechanisms that your model uses should be housed inside a strong and stable structure.

On the one hand, the double-toggle jaw crushers have a more complicated mechanism that creates a more uniform product size and a more efficient crushing. On the other hand, they are often more …
Size Reduction – Visual Encyclopedia of Chemical …
The hammer crusher, also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device. As the disc rotates, the feed material is struck and crushed by descending hammers until it is fine enough to pass through a screen or openings and exit the device.
