Sintered brick process is composed of four parts.To sum up,it is said that the raw material is fundamental,molding is the basis,drying is ensure and roasting is the key. These four parts are interdependent.

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.

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.
