| Inside the mill |
 |
We are looking inside this mill and you can see the wheat
kernels falling between two rollers. Those rollers are spinning toward
each other at a high rate of speed and they will crush the kernels.
(Actually, one roller is spinning slower than the other one. This gives
the rollers a better cracking action.) |
 |
Here are two steel rollers that crush the wheat kernels.
These rollers are for exhibition and they have been cut in half. So,
normally they are twice this long. The steel rollers were first used in
1878. They were a great improvement over what was being used until that
time. Look at the next picture. |
 |
Before steel rollers were invented millers used millstones
like these. The bottom millstone remained stationary while the top stone
turned and that action crushed the wheat. The wheat is feed into the
middle of stones and the flour and bran work their way to the outside of
the stones. These millstones are made of marble. |
