Heavy calcium carbonate powder is the powder made only by grinding greda, limestone, and calcite. The white powder contains CaCO3, with stable chemical property. It is also the raw material of glass and concrete. It can also act as filler for rubber, paint and plastic. Moreover, it plays an important role in paper-making due to its whiteness.

Concentrated (e.g. above 72% by weight) dispersions of calcium carbonate ground to a particle size such that at least 87% by weight of the particles are less than 2 μm in size have a tendency to gel on standing. In the invention this tendency is minimized or eliminated by using, as dispersing agent, a copolymer of from 5 to 75% by weight AMPS and 95 to 25% by weight …

Alphastone factory is one of the most important factories which grinds and packs calcium carbonate. And the process of processing and classifying the different degrees of calcium carbonate in the factory is done according to its uses in various industries. Some industries use softness less than 4 microns while others are greater than 10 microns.
