1.Product Programme
Name: Fired brick  
Specs(mm): 240×115×53
Capacity(bricks/year): 30,000,000
  
2. Technical Scheme
In view of the practical condition of raw clay, a technical scheme reliable in technique and practicable in economics is chosen. According to this principle and in view of the construction field, this project adopts once setting technology.
