Project location: Cixi, Zhejiang Province, China

Hourly output:20,000 pcs-25,000pcs (standard bricks)

Raw materials: Silt, construction waste

This clay brick project used a typical brick making engineering process with two type raw materials mixtures. The main material is silt, which is rubbed by double rollers crusher after stone removal, and the auxiliary material is building waste, which is sieved after hammer crushing, and the two materials are mixed and for aging. At the same time, the project adopts one and half green brick stacking and for firing technology, the green bricks are firstly stacked by a robot to the kiln car for 7 layers, and then enter the drying room for drying through green brick storage line. After drying completed, green bricks will be stacked higher from 7-layer to 14-layer and after that the dried bricks enter into firing kiln for sintering.

The aging warehouse of the project adopts a bridge-type multi-bucket excavator, which has the characteristics of good aging effect of raw materials, bigger amount of aging inventory, and more reasonable material extraction by the excavator. The brick machine has a high degree of automation after extruding the mud columns. Using two robots to stack 7-layer green bricks. And due to one and half green brick stacking and firing technology, the kiln car could load more green bricks, the firing kiln has output, and the bricks are sintered with better quality.

The tunnel kilns with cross-section of 3.7m, six tunnels for baking and three tunnels for burning, with an annual output of 150-200 million pieces (equivalent to Chinese standard bricks).
