Clay is one of the factors critical to the quality of terracotta panels. During the production cycle of Terracotta Cladding, the production line just takes relatively short time. In contrast, more time is spent on clay preparation, which includes raw-material selection, natural souring, batching and grinding.
Due to the constraint of space and equipment, most of Terracotta Panel manufacturers in China are using the clay processed by suppliers who mix the clay before grinding it into power. It is rather difficult to guarantee the consistency and stability of such clay that is sourced from outside suppliers. This consequently poses a big challenge to th controlling of the quality and color difference of terracotta panels.
As a professional manufacturer of terracotta exterior wall panels in China, Paneltek fully understands the importance of clay for terracotta panels. To monitor the clay preparation process and make adjustment in a timely manner, Paneltek planned an open-air stock yard of 80,000 square meters when it stared planning for plants The stockyard is used for storing 300,000 tons of natural clay. Paneltek is also equipped with an indoor system for 12,000 tons of finished clay mud. Meanwhile, with 5 large high-performance Raymond mill, Paneltek is able to grind the clay to the desired particle sizes, which guarantees the maximum extent of physical and chemical changes in the process of clay calcination. These facilities give Paneltek the maximum control over the quality of clay, which not only ensures the consistency and stability of clay to the most extent, but also enables the clay to sour naturally and thoroughly. As a result, for large-scale terracotta facade panel projects, Paneltek obviously has its competitive advantages over most of other manufacturers when it comes to quality, color stability and lead time of terracotta panels.
