DEVICE FOR MANUFACTURING SUPER-ACTIVATED CALCIUM CARBONATE SUPERFINE PARTICLE

摘要

PURPOSE:To pulverize the aragonite based calcium carbonate lump into superfine particles by providing a circular tube, an inlet door of feeding the aragonite based calcium carbonate slump provided on this circular tube and the inlet and outlet of N2 provided on this circular tube and N2 running means to executes running force to the relevant aragonite based calcium carbonate lump so as to rotate in this tube therein. CONSTITUTION:The aragonite based calcium carbonate lump is charged into the relevant tube from charging door 2. Inlet and outlet of gaseous nitrogen 3 are provided on the circular tube and N2 is charged into the tube 1. The running means 4 of the aragonite based calcium carbonate imparts running power so as to the aragonite base calcium carbonate lump is rotated in this tube 1. Since by the rotation of gaseous nitrogen the pulverization afford at low temp. and also by the friction between the particles themselves the lump goes to superfine particles, the superfine particles are manufactured without loosing the specific properties of the aragonite based calcium carbonate.
