Drying of bricks In the brickmaking process, the clay is refined and water is added in order to mould the brick. Before the bricks can be fired, they must be dried properly: the moisture content has to be reduced to 8% of volume for the clamp kiln. In South Africa, there is adequate sun for the drying operation and most clamp kiln brickmakers make

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...
