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.

From the above table, it can be clearly seen that the plasticity index, dryness sensitivity index, and dry linear shrinkage of the mixture tend to increase with the increase of the particle composition below 0.5 mm in the mixture.This fully shows that the use of geotechnical test method can not fully evaluate the properties of plastic materials such as shale and coal gangue that rely on reducing particle size.From the above analysis, the plasticity degree has a great relationship with the particle size of clay minerals.

1, Malformed adobe, appears large cracks. In more serious cases, the whole adobe will split.

Reasons: the plasticity index of pug is too low, almost no plasticity.

Solution: to increase the plasticity index of raw materials, such as clay, coal slime or clay agent, etc.

For raw materials of low plasticity index, it can also be improved after aging, watering, stirring, rolling, extruding and other methods.
