Manufacturing of Bricks

 The main steps followed to make Quality Bricks:     
1. Material Procurement: The clay is mined and stored in the open. This makes the clay soft and removes unwanted oxides.
2. Tempering: This clay is then mixed with water to get the right consistency for moulding. 
3. Roller crusher: The clay is fed into the roller crusher where it is reduced in size to small granules. 
4. Mixer: The sized clay particles are fed into a mixer for uniform mixing with water. The mixed clay is fed into extruder through conveyor belt.
5. Extrusion: The clay body is mixed to a fairly stiff texture and is then loaded into an extruder where a  screw pushes it along a barrel into a vacuum chamber which compresses it through a taper and out through a die. The die is machined to a precise size and shape larger than the finished size of the brick, calculating how much the clay will shrink during and firing process. The clay emerges as a continuous brick shaped column. The clay column is then cut into single bricks.
6. Drying: Before the bricks can be fired, as much moisture as possible must be removed or they will explode in the kilns. Drying under then shed involves the removal of water from the wet brick in such a way as to dry them out evenly from inside out.
7. Firing: The green bricks are arranged in a kiln and insulation is provided with a mud pack. Fire holes left to igniter the kiln are later sealed to keep the heat inside. The finished product is brought out of the kiln for sales
