Chapter 2 Technical Specification of the Project
2.1 Technical Design &Process
Technical Design: Comprehensive consideration of raw material, brick shape, dimensions, weather, operating skills of workers and degree of mechanization operation in Azerbaijan:

         


Whole brick project adopts Twice brick stacking and firing technology;

• Raw material: soils from the buyer
• Green brick forming: automatically;
• Green brick setting on kiln cart: by two sets robot
• Finished sintered brick discharging: by manual.

2.2 Raw Material Handling
 According to raw materials performance, firstly use teeth-roller crusher to break all lumps; then, use a

roller and one fine double-roller crusher to make sure granules in raw material can be evenly crushed and mixed to size less than 2mm. The fine raw material will go through box feeder and belt conveyor into double-shaft mixer, adding water for fully mixing.
2.3 Green Brick Forming
Clay come out from mixer shall go into double-stage vacuum brick machine and pressed into predetermined strip dimensions. Right after auto strip cutter and adobe cutter come out suitable sized green bricks.
