WELLWARES-Ceramic drying and trimming

After the initial forming of the product is completed, the product is sent to be dried immediately after forming. Due to the influence of the moisture in the mud, the tableware is very easy to deform, resulting in that the tableware cannot be directly fired at this time, so at this time we need to adjust the blank After drying, the strength of the green body is improved after drying, which is conducive to handling, kiln loading and firing. The reduction of moisture can prevent waste products due to the large amount of moisture discharged from the green body during the initial stage of firing and increase the forming rate of the product. But drying is not blindly draining the water, the body can leave about 2% of residual water after drying. The edges and corners of the over-dried green body will be brittle, and it is easy to produce waste products during transportation, and it is not economical at the same time.


According to the different water content of the mud, it can be divided into two stages: constant speed drying and reduced speed drying. Use adjustable drying room. Adjust the drying chamber according to the characteristics of different raw materials to make the internal structure of the product more compact and strengthen the product strength. The product blank will be trimmed next.


Before trimming the ceramic, we check the product with kerosene for cracks. Use sandpaper on the roller to smooth the edges and sides of the upper and lower ends of the product. Smooth the outer surface of the blank to improve the yield of the product. Ensure that the later production process continues.
