Because of its many characteristics, ceramsite has its own unique requirements in the selection of raw materials.
The process of ceramsite formation can be briefly described as the drying of raw materials to remove moisture, calcination and foaming and ceramic formation, and stable cooling.
When selecting raw materials, we must analyze and control the production factors from the pottery process. One is the plasticity of the raw materials, the other is the pottery elements of the raw materials, and the other is the origin of the cooling process. Finally, the temperature curve of the kiln body and calcination is designed according to the pottery process.
Plasticity: Since the elements enter the drying system after being pelletized by the pelletizing equipment, we must ensure that the materials are not scattered during the drying process, which is the most basic requirement for us to select raw materials. Generally, it is most suitable that the plasticity index is around 8-9.
Pottery-forming process: The pottery-forming process is a process of calcination at high temperature to form gas and form an enamel layer on the surface of the material ball, so that the gas is not suitable for bursting, and gradually grows up. This is mainly related to the framework elements of silicon dioxide, aluminum oxide, flux potassium oxide, calcium oxide, magnesium oxide, calcium oxide, and gaseous elements such as iron oxide and titanium oxide. During calcination, the porosity must be continuously increased, the compound decomposition, crystal water decomposition, etc. will produce gas, but to ensure that these gases do not leak, it is necessary to find raw materials in accordance with the proportion of ceramic elements.
Cooling process: The cooling process should be selected according to the calcination temperature of the material and the characteristics of the material. We should study the elements of the material and find the cooling process according to the elements contained.
In the selection of ceramsite raw materials, we must finally make a comprehensive account based on the most suitable economic ratio of each region, so that we can find suitable production raw materials. After more than ten years of painstaking research, Henan Zheng Mine has determined the ratio of raw materials through small and pilot tests, and escorted your industrial investment.
