Brick handling apparatus

[cicididi]

Bricks have long been a versatile building material. Generally they are made of clay or shale. However, when used for special applications such as paving or refractory materials, the clay or shale is usually supplemented with other materials such as slag, cement, or lime. Usually, such special-purpose bricks are referred to by descriptive names such as fire- brick or sand-lime brick.
In the manufacture of brick extruder, selected clay soil is thoroughly ground and mixed with water. This mixture is then "fired" or heated in a controlled manner to produce finished bricks. For many years, the bricks were formed individually by placing the unheated mixture in moulds and then firing the bricks in a kiln. Generally, the bricks were made with manual labor throughout the process.
