Calcium Carbonate Milling Equipment

Precipitated calcium carbonate is produced using the most economic process existing today. Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900буC. To ensure a high level of purity, the calcination process is carried out using natural gas. After the calcined lime has been slaked with water, the resulting milk of lime is purified and carbonated with the carbon dioxide obtained from the calcination process.

Calcium Carbonate Production Plant

In calcium carbonate production line, the raw material will be first mined from the deposit. After quarrying, further treatment is required to process natural calcium carbonates (and dolomite, which is very similar) of the highest quality, known generically as Ground Calcium Carbonate.

Calcium carbonate processing includes crushing, grinding, washing, sorting of undesirable contaminants, size classification of particles and possibly drying. Depending on the circumstances and intended uses, the order and necessity of those different steps vary. At the outlet of the process, the material is delivered in bags or in bulk when dry, or as bulk tankers for slurries by road or rail.

Calcium Carbonate Milling Equipment

Milling the important stage in calcium carbonate producion process, it is the size reduction operation and consists of crushing and grinding applications. A wide range of mills has been developed for particular applications.

SBM design and manufacture a comprehensive line of grinding mills and entire grinding systems for mining, industrial minerals industry, coal and cement, including classifiers and related accessories for both wet and dry grinding systems.
