stone powder and toothpaste

Toothpaste consists of abrasives, fluoride, surfactants, antibacterials agents, flavorants, reminerlizers and misceelaneous compoments.
 
For abrasives, it mostly use nature calcium carbonate, like calcite powder, barite powder, limestone powder, etc. These powder must be more than 800 mesh, and the flour is about 70 mesh, you can image the fineness of 800 mesh. For such fine powder, we have to use a large industrial ultra fine vertical powder mill, which also can be called vertical roller mill. This type machine use mechanical working principle to grind the stone into ultra fine powders. It may seem like quite easy to process, some laymen may think you can grind the stone into powders by yourself. For 2100 mesh, that is 30 times thinner than the flour we use. In all this process is easy, but also not easy, you can read the working principle details on http://www.vertical-mill.net/mill/vertical-powder-grinding-mill.html.
