gypsum is now ready to be ground. The rock is ground in a rollertype crushing mill called a Raymond mill. These powerful machines grind the gypsum into a fine powder, called "land plaster." The land plaster is then fed into Gold Bond's patented Calcidyne System, where it is "calcined," or heated to remove three
