Calcium Carbonate Granulation is a food-grade granulated form of calcium carbonate designed for direct-compression tablet manufacturing.We supply bulk Calcium Carbonate Granulation sourced from leading China manufacturers, available in granular form to meet global food industry demand. Our Calcium Carbonate Granulation is widely used in direct-compression calcium tablets, chewable calcium supplement tablets, multivitamin/mineral tablets, antacid tablets and pharmaceutical solid-dose forms.
Calcium Carbonate Granulation is produced by wet or dry granulation of fine calcium carbonate powder to create uniform granules with superior flow, compressibility and content uniformity for direct-compression tablet production.
Eliminates the need for separate granulation steps in supplement manufacturing.
