If the residual moisture rate after drying is less than 6%,the wet billet could be fired in the baking kiln.Hoffman kiln and tunnel kiln are normally used for roasting.When using Hoffman kiln, the brick code is manually placed in the kiln and the fire is roasted in the kiln.When using tunnel kiln,the brick code is manually or mechanically placed in the kiln cart.The kiln car enters kiln head and exits from the kiln tail. The brick blanks on the kiln car are roasted into bricks.The roasting flame in the kiln doesn’t move just the kiln cart.Whether using Hoffman kiln or tunnel kiln,this two conditions must be followed:1.never use underfire to produce unburnt brick.2.never use big fire to produce coke brick.It is often said that roasting is the key of the brick making process,which explains the importance of roasting in the brick making process.

This method has been widely used for many years in the fields of soil science and engineering geology.Although China's brick and tile industry has been using it for many years, it is only for soft and dispersed clay raw materials.For coal gangue, shale, etc., which rely on reducing particle size to obtain plasticity, there is a great deal of deviation in using this method.For example, the plasticity of raw materials such as coal gangue and shale depends on crushing to reduce the particle size to a certain degree, adding water to the particles after decomposing (aging), and it is changeable during processing.If the hard clayey shale or coal gangue rich in illite is ground to a sufficiently fine degree (such as cement fineness),the plasticity index may reach a pretty high level.And formed moisture content and drying shrinkage may be larger than common clay materials, which totally differ from common brick clay.

why clay brick break, why clay brick crack ,why does brick crack?

Most of brick factory owners spent a lot of time and fianace to start their brick factories, however,not all of them get success, the reasons is that before starting clay brick factory, they did not conduct enough study and servey. To avoid investment loss for clay brick production, we have made the following summary for the common phenomenon of poor quality bricks and common mistakes the new clay brick facotry owners always make.
