How to prevent bricks from cracking during the drying process?

2025-05-10
Latest company news about How to prevent bricks from cracking during the drying process?
  1. Strengthen raw material processing, reduce molding moisture, and improve the strength of the brick. 
  2.  Increase the temperature of the brick. The relative humidity of the exhaust gas should be controlled at about 95%, not too high, to prevent condensation from forming when the brick enters the drying channel, which will hinder the discharge of moisture inside the brick. Then, the brick will suddenly encounter high temperature and low humidity gas, causing the brick to dehydrate rapidly and crack.
  3. Control the residual moisture of the brick after drying to about 6%, and put it into the kiln in time to prevent the brick from absorbing moisture from the outside and cracking due to low residual moisture.
  4. When the fan is temporarily stopped due to power outage or maintenance, the inlet and outlet doors and inspection ports should be opened to allow moisture to escape, so as to prevent the brick that has lost some moisture from absorbing moisture again in the drying channel and cracking.
