Yes, that's what they were originally used for.
The wind would turn the windmill's sails, which would in turn operate large grindstones inside the mill.
These stones would crush the grain to make flour.
Stone-grinding is still used today as a method of grinding grains (it produces a distinctive flavour), but the energy to operate the stones usually comes from an alternative source (after all, wind doesn't always blow on cue!).

...Shoud've read the question a bit more carefully.
I read it as 'to grind grain', not 'to produce grain'.
Of course, a windmill itself cannot produce grain.

The pinnacles of windmill design include those built by the Dutch, who used windmills extensively to pump water as well grind flour.
These days the power from the wind lives on, both in the form of wind turbines producing electricity, and in the form of small scale wind pumps (often largely low-tech "appropriate technology" installations) still used extensively in world agriculture.

The purpose of a windmill is to produce "power" by harnessing the wind.
This power can be used to grind corn, pump water or even generate electricity.
Electricity generation from windmills is nothing new, it has been around for over 125 years.
