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.

Some kiln owners are not willing to spend money in equipping the machinery of raw material pre-treatment, such as roller crusher,double shaftmixers. Some kilns are only equipped with a pair of rollers, some only with mixers, some even neither of them. How can we get good bricks if there are bricks, tile, stone and other debris in the mud raw materials? Even if it is hard to send someone to pick them out clean. The fundamental way to solve the problem is equipped with auxiliary equipment.

Any kinds of soil can be used for making bricks?

Most of soil can be used for making bricks, but soil plasticity must be between 5 to 17. If the soil plasticity is too big or too small, you need to add additional material in the soil.
