Procedure for the Compaction of the particles of zinc oxide from its original State in powder formA device for applying Said method and Granules, zinc oxide thus obtained.

摘要

The.Procedure consists in subjecting the zinc oxide Powder mixed with a Plurality of beads made of a rigid material.A Movement of a Rotary Drum helicoidaldentro Tilted down slightly in the sense that it goes from an Inlet end to an outlet end of the Drum.The rotation of the drum and the inclination of the same cause of dust particles and the Balls are drawn and elevated until, poraccion of gravityThe particles start to fall and crowd.Some of the beads Slide down along the Wall of the Drum, produciendoun kneading effect which promotes the Agglomeration of the Powder particles.Other Balls REACH a height up verticalmentesobre agglomerated particles causing a Hammering effect that increases the consistency of the same.The Rotary drum is interiormentedividido sections Progressive Compaction of PowderBy means of a Plurality of annular fins with Small holes for the passage of particles from each section to the Next.Finally, the obtained zinc oxide Granules, whose size is of the Order of 5 times greater than original particles, increasing the apparent density.
