Patent ID: 7695528

Claim:
A process for preparing a calcium carbonate granulation comprising the steps of: (a) mixing, in a mixer capable of creating high shear, a composition comprising: (i) calcium carbonate powder having a median particle diameter between about 10 to about 12 μm; (ii) between about 5 to 20% by weight water based on the weight of said calcium carbonate powder; and (iii) one or more excipients selected from the group consisting of diluents, binders, glidants, lubricants, disintegrants, colors, flavors, sweeteners, solubility retarding agents, and combinations thereof; and (b) drying the composition to a water content of less than about 1% by weight in a drier selected from the group consisting of a tray dryer, a vertical fluidized bed oven, a horizontal fluidized bed oven, a spray dryer, and an impingement oven; to provide a calcium carbonate granulation having sufficient cohesiveness and compactability for compression into pharmaceutical or nutraceutical supplement tablets.
