Tile production process

1. Raw materials: The main ingredients are clay (can be divided into black mud to improve the plasticity of products; white mud to improve the whiteness of products) and sand (the main ingredient is SiO2, used to improve the strength of products, etc.);

2. Ball milling: The grinding process makes the raw materials reach a certain fineness and uniform composition. At the same time, in order to promote ball milling, about 34 to 37% water should be added during the grinding process. Grinding balls mix sand;

3. Spray granulation: Principle: In the spray drying tower, the full convection of 600 hot air sent downwards from the hot air stove and the upward spray suspension are used for drying and granulation. , forming hollow particles of raw materials. Produce raw materials to ensure a good combination of raw materials in the compression molding stage;

4. In the powder warehouse (raw materials are rancid): The raw materials are naturally placed in the warehouse for more than 48 hours to ensure the uniformity of raw material moisture and the physical and chemical properties. Consistency;

5. Press molding: The tonnage of the press and mold determines the resistance, size, cracking and other major defects of the product. If there are problems, the overall quality of the ceramic tiles will be reduced. Later, the Use restricted.
