    Clay Processing

    Process Description14 Clay is defined as a natural, earthy, finegrained material, largely of a group of crystalline hydrous silie minerals known as clay minerals. Clay minerals are composed mainly of silica, alumina, and water, but they may also contain appreciable quantities of iron, alkalies, and alkaline earths. Clay is formed by the mechanical and chemical breakdown of rocks ...

    The Pulp and Paper Making Processes

    In the stone groundwood process, debarked logs are forced against rotating stone grinding wheels that are constantly washed by a stream of water. The ground pulp is then screened to remove course debris, thickened, and stored for the papermaking process. Chips are used to produce refiner pulp and thermomechanical pulp. In both processes the ...
