The old Grist Mill in the photo above is situated north of the town of Rowley, Alberta, it is missing the windmill that drove it and sat on top of the cone on the roof. The workshop and all of the grain storage buildings are all still on this site.The Grist Mill was described as a fine grist mill which grinds both course and fine flour. The heart of the Grist Mill was it’s grinding stones. Grinding stones were used in pairs. The bottom stone, or bed stone, was fixed into position while the upper stone, or runner stone moved. The stones were connected to the power source, the wind in this case by a wooden counter wheel wedged on the horizontal drive shaft which ran the trundlehead, a small wooden lantern gear. The trundle-head shaft usually called the spindle turned six or eight times as fast as the wind wheel shaft. Grain dribbled from the hopper and was guided by a spout into the while in the runner stone. It was moved outward by the centrifugal force as the stone ground it. The flour and bran were confined by a wooden casing that covered the stones. It could escape only down a chute that led to a wooden bin on the floor below. From there flour and bran were removed, separated and processed ready for use.
