gypsum deposit at Fort Dodge as "by far the most important bed of plaster-stone known west of the Appalachian chain if not in the United States." The success of the first gypsum mill in the region, the Fort Dodge Plaster Mill built in 1872, led to the construction of others. By 1902, seven mills were operating and producing a variety of
The ground gypsum exits the mill in a gas stream and is collected in a product cyclone. Ore is sometimes dried in the roller mill by heating the gas stream, so that drying and grinding are accomplished simultaneously and no rotary dryer is needed. The finely ground gypsum ore is known as landplaster, which may be used as a soil conditioner.
