Old Stone Mill - Stone Grinding Flour
The Old Stone Mill is a Grist* (flour) Mill, built in 1810 with the specific purpose of grinding wheat into flour. This grinding is done with a set of millstones, the bottom stone fixed, the top one rotating (at about 90 rpm), the slight gap between the stones allowing the entry of wheat between the stones.
APS Pedestal Grinding
Grinding is the process of removing material by the cutting action of the countless hard and sharp abrasive particles of a revolving grinding wheel as they come in contact with the surface to be ground. Grinding machines are made in a variety of types and sizes, depending upon the class of work for which they are to be used.
