Detailed introduction to the preparation method and process flow of 400-mesh ultrafine heavy calcium carbonate. 400-mesh ultrafine heavy calcium carbonate is an important inorganic chemical raw material with a wide range of applications. Guangxi Longhua New Materials Calcium Carbonate Wholesale provides a detailed introduction to its preparation method and process flow:

　　Preparation method:

　　1. Raw material preparation: Prepare high-quality limestone ore as raw material.

　　2. Crushing and pulverization: The limestone is subjected to preliminary crushing and pulverization to make the particle size suitable for further processing.

　　3. Pretreatment: Use appropriate pretreatment methods, such as washing and screening, to remove impurities from the limestone.

　　4. Carbonation reaction: The pretreated limestone is carbonated with carbon dioxide. Wet carbonation or dry carbonation methods can be used, and the appropriate process is selected according to specific needs.

　　5. Filtration and washing: The resulting calcium carbonate slurry is filtered and washed to remove impurities and dissolved substances.

　　6. Drying treatment: The washed calcium carbonate slurry is dried to obtain a solid calcium carbonate product.

　　7. Crushing and classification: The dried calcium carbonate product is crushed and classified to obtain 400-mesh ultrafine heavy calcium carbonate.

　　Process flow:

　　1. Raw material preparation and crushing and pulverization: The limestone ore is pre-treated to make the particle size suitable for further processing.

　　2. Pretreatment: The limestone is washed, screened, and pretreated to remove impurities.

　　3. Carbonation reaction: The pretreated limestone is carbonated with carbon dioxide.

　　4. Filtration and washing: The calcium carbonate slurry is filtered and washed.

　　5. Drying treatment: The washed calcium carbonate slurry is dried to convert it into a solid calcium carbonate product.

　　6. Crushing and classification: The dried calcium carbonate product is crushed and classified to obtain 400-mesh ultrafine heavy calcium carbonate.

　　The above is a detailed introduction to the preparation method and process flow of 400-mesh ultrafine heavy calcium carbonate. Hope it helps you.
