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 need to analyze and control the production factors from the pottery process, one is the plasticity of the raw material, the other is the pottery element of the raw material, and the other is the origin of the cooling process, and then the kiln body and calcination are designed according to the pottery process. Temperature curve.
1. Plasticity
Since the elements enter the drying system after being pelletized by the pelletizing equipment, during the drying process, it is necessary to ensure that the materials are not scattered, which is easy to cause pellets, which is our basic requirement for selecting raw materials*. It is generally required that the plasticity index is around 8-9 as the most suitable.
2. Pottery process
The pottery-making 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 out, it is necessary to find raw materials in accordance with the proportion of ceramic elements.
Three, cooling process
The cooling process should be selected according to the calcination temperature of the material and the characteristics of the material. We have to study the elements of the material and find the cooling process according to the elements contained.
The selection of ceramsite raw materials must be comprehensively calculated based on the most appropriate economic ratio of each region, so as to find suitable production raw materials.
