A machine to crush grain will usually be powered by an electrical motor that provides rotational movement. 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.
