brick making machine

 

Generally two types of bricks are manufactured by the machines- concrete block machines and clay brick machines. Different types of automatic machines use different techniques to make bricks. The raw materials used by the machines for making bricks are fly ash, sand lime, iron oxide, lime sludge, quarry wastes etc.
 
In clay brick making machine, clay and water is mixed in one chamber. In second or extrusion chamber clay is given shape with the help of the die. The size of the bricks vary according to demand. The die is also used for making hollow bricks, perforated bricks and designer bricks. The clay is cut by the cutting machines and taken to the drying sheds for initial drying.
 
The basic raw materials used for making the blocks are fly ash, gypsum, cement, sand etc. Concrete blocks are generally made by machines having different molds. The tabletop vibrator in machine provides optimum vibration in the mix so that the ratio of cement used can be reduced substantially without affecting the strength of the blocks.
