This is still the result after revalidation according to the geotechnical test method,which fully demonstrates that the current geotechnical test method used in the brick and tile industry can’t correctly reflect the characteristics of raw materials such as coal gangue and shale during processing and forming.In order to further prove the fact that raw materials such as shale or coal gangue relys on reducing the particles size to obtain plasticity, the hard shale in a place near Shijiazhuang was crushed into two groups in the laboratory.One group all can pass 0.9 mm sieve; the other can all pass 0.5 mm sieve.However, the shale of the same mineral composition differs greatly in its plasticity index only due to its different grain sizes, one being 4.8% (0.9 mm) and the other being 8.9% (0.5 mm).In order to further verify this phenomenon, this two groups were blended together in different proportions to determine their plasticity index, drying line shrinkage rate and drying sensitivity index. The results are shown in the following table.

The above mixing stage is made of two sets of extruding auger, not common mixing blades, therefore, it is much better for hard raw material, and raw extruding after 2 times extruding, upper and lower extruding, will become more solid. Therefore brick quality is much higher.

There are two kinds of kiln for you to choose: tunnel kiln, hoffman kiln. Hoffman kiln with tunnel dryer is also good for this production line. (cost less than tunnel kiln and more efficient than hoffman kiln) If you want to learnmore information, please contact us.
