The natural drying is to place the wet billet on the billet stalk in the natural drying place,manually invert the code and use the atmosphere to wet the cold billet into a dry billet.Artificial drying is to use equipped artificial drying chamber to dry wet billet.The artificial drying room is divided into three types: large-section tunnel drying room, small-section tunnel drying room and chamber drying room.Whichever type is adopted, it is manually or mechanically placing wet billet on a drying truck,then put it into drying chamber.The heat medium in the drying chamber generally comes from the waste heat of the sintering kiln or the hot blast stove.Whichever drying method is adopted, it must be ensured that the blank will not be deformed or chapped during the drying process.If the wet billet can’t guarantee the appearance quality of the product during drying, it will cause high reject rate, falling output,increasing cost of the finished brick, which are definitely harmful to company economic efficiency.This shows the importance of drying wet billet in brick making process.

The plasticity index of common brick clay is relatively stable.In terms of this type of material, which depends on crushing process reducing particle size to obtain plasticity, its plasticity index is variable during processing.For example, when a certain coal gangue is crushed below 0.9 mm in the laboratory, according to geotechnical test method, the plasticity index is measured as only 7.2%.However, after adding 40% of excessively fired vermiculite (essentially no plasticity),then adding water, aging, and crushing on the roller, vacuum extrusion,plasticity index of the small sample actually reached 10.5%.For example, when other shales were crushed to less 0.9 mm, the plasticity index is measured as 8.4% according to geotechnical test method.However, after adding 40% (by weight) of fly ash,then mixing with water, aging, and crushing,plasticity index of the small sample extruded by the vacuum extruder reached 9.5%.

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.
