Calcium Carbonate 培林企業有限公司

Calcium carbonate is currently chiefly produced via two types of processes: One involves the mechanical crushing of natural limestone to produce calcium carbonate of different finenesses. This type of calcium carbonate is known as heavy calcium carbonate; its quality is determined by the quality and fineness of the natural limestone.
