Barbotine (natural clay)
Spray drying has been explored as a technique for the production of barbotine powders, which are composed of natural clay suspensions. Barbotine, also known as slip, is a mixture of clay and water used in various applications, including ceramics, pottery, and construction materials.
The areas of focus in spray drying of barbotine include optimizing the process parameters, such as the inlet and outlet temperatures, atomizer type, and feed rate, to achieve the desired particle size, morphology, and moisture content of the powder. Additionally, research has been conducted to evaluate the impact of different drying conditions and formulation additives on the physical and chemical properties of the powder, such as its shrinkage, porosity, and sintering behavior.
Moreover, spray drying of barbotine has been investigated for the production of ceramic powders with controlled properties, such as uniform particle size distribution and improved flowability. These powders can be further processed through techniques like pressing, molding, or extrusion to create intricate ceramic shapes and structures.
Overall, spray drying of barbotine offers a promising approach for the production of homogeneous and easy-to-handle powders, providing opportunities for advancements in ceramic manufacturing, construction materials, and other related industries.
